Which Should You Choose Concrete Cutting or Concrete Drilling?

What is concrete cutting?

Concrete cutting encompasses not only the actual cutting of concrete but also its drilling and removal. For the actual cutting segment of this material, concrete saws are used for this specific job requirement. These saws, based on their modern technology, have greatly replaced the jack hammer in many instances. They have the capability of making precise cuts and leaving a smooth clean finish. They also greatly reduce the dust that comes with concrete cutting.

There are various ways of cutting a concrete. These include slab cutting or sometimes referred to as flat sawing. There is core drilling and wall sawing. There are many different tasks within the construction industry that completely involve concrete cutting. It might be for the purposes of partial removal of a foundation or addition to existing building including residences.

Cutting concrete slabs is another common requirement in any construction job. No matter what the task at hand, it will surely demand the need for the right type of concrete cutting equipment. And this should only be done by an individual who has the training and skills to operate this type of equipment.

What is concrete drilling?

Concrete drilling involves digging of a hole in a certain concreted area. These holes are dig for many different purposes. It may be used when something has to be anchored in the concrete, such as large shelving units or other components. It may also be needed for electrical requirements and for mechanical or plumbing purposes.

The equipment used for this job requirement is called a diamond core drill. This has been designed to drill precise holes in a certain piece of concrete. It has the shape of a cylinder that can cut a precise and accurate circular hole. The size of the hole made depends on the drill bit being used and the depth it is required to cut. The drill bit is capable of removing the core of the cement hole being created.

There are different makes and models of diamond core drills. There are also different sizes of bits. Concrete drilling should be carried out with wet or dry concrete drilling techniques. These options will depend upon the job that is being required.

The basic diamond core drill is composed of the following:

  • Motor
  • Spindle connection
  • Locking switch
  • Gearbox
  • Handle

There are also other models of diamond core drill that may have additional compositions which include:

  • Dust extraction
  • Water supply
  • Electronics

The size, make and model of the core drill will depend on the type of job it is required for and how often it will be used. Some confusion will come into play if the layperson is not familiar with concrete drilling and which type of bit to use.

There are two most common types of equipment for concrete drilling. These are the diamond drill bits and the carbide. The type of concrete you are going to work on will determine which type of drilling equipment you are going to use. The depth of the drilling required also matters and whether you are going to be drilling on wet or dry concrete

The proper completion of concrete drilling usually requires that the holes being made are perfectly round. These holes can range anywhere between 1” to 12”. For commercial needs, they could be up to 60” round or even more. They also require the expertise of a highly trained person in the proper drilling of concrete.

There are a lot of judgement calls and selections of concrete drilling equipment to be made. This can be dependent on the project manager if this type of task isn’t present on a constant basis.

Conclusion

Doing any type of concrete cutting or drilling even if it is a small job can sometimes be difficult. It is not a forgiving task and when you make a mistake you simply need to start over again. Cutting too much or too little of the concrete or drilling a hole that is too big or too small can create a lot of extra work to try and fix the error.

The best and sure-fire way to ensure that the concrete is being cut or drilled precisely is to utilise a company that is specialising in this field. You can always find a reliable service provider in Melbourne, Australia such as Megasaw. They can guarantee that your required tasks are going to be done quickly, and effectively both in the requirements and cost.

They highly stand on reliability and performance, which are a much needed aspects in the construction industry.

8 Easy Steps for Cutting, Breaking and Removing Concrete

Cutting and removing concrete would sound like a very formidable task to do. This is true especially with those involving street pavement being broken and demolished to give way to a new concrete pavement. These kinds of construction jobs are usually done by big-time contractors.

But as uncommon as concrete removal may look in the domestic sense, there are actually many household situations where we may find ourselves being confronted by a need to cut and remove concrete. It may be a repair of water or drain leak in your house or yard or a plan to replace the concrete covering in one part of your garden with decorative grasses and plants. In any case, it pays to know what and how to do it, even if you have in mind to hire a contractor to do the job for you.

Below you will find the basic steps in the concrete cutting and removal job. These steps assume that you already have a clear purpose for the activity and that you have identified the area where cutting is to be made.

1. Prepare the Site

Concrete cutting and removal is difficult if surface is dirty and congested. If there are clutters restricting the movement of workers, ensure that the site is cleared of these barriers to movement. It is also important that items which may be damaged by dust or by chipped concrete fragments during cutting are covered with protective mats or sacks. Check also that the passage way for moving the rubbles is clear when the broken concrete is removed from the site.

2. Ready Your Tools

For most concrete cutting jobs in the home, the following are the most common tools needed:

  • Electric circular saw with diamond or abrasive blade
  • Sledgehammer
  • Jackhammer
  • Large pry bar or a pick
  • Shovel
  • Bolt cutters for wire mesh
  • Demolition saw for rebars

3. Ready Your Safety Equipment

Concrete cutting and removal, by its very nature, is a dirty job as it means rousing dust from its compaction inside the concrete. Add water and you’ll have a mess of the mud that is created. It is also a job involving risks as tiny fragments of concrete may fly at different directions. Hence, you need safety tools and protective gadgets to keep you safe from harm. These include:

  • Chalk for line marking
  • Straight-edge piece of wood for guide
  • Thick gloves
  • Goggles
  • Ear protective gear
  • Dust mask or respirator
  • Steel-toe boots or equivalent work shoes
  • Clothes thick enough to cover you from the elements

4. Lay out the Area

Establish the demarcation enclosure using a straight-edge piece of wood long enough for the purpose. Use coloured chalks in lay-outing and make sure that the line marks are wider and will be readable enough even from a distance.

5. Start the Cutting

Set up your concrete saw to cut at 2 inches (50 mm) blade depth over the guide line. This line cut is for making sure that the edges of the remaining concrete are straight and smooth when the new covering is installed. At the same time, it prepares the line-enclosed area for the subsequent concrete breaking procedure. As the cutting is being done, spray the surface area around the blade with soft sprinkles of water. This is in order to lessen the dust and to prevent the blade from overheating. However, be warned not to sprinkle water on the electric saw. After completing the line cut, if you wish to deepen the cut to 4 inches (100 mm), adjust the blade in the cutting saw and repeat the steps.

6. Breaking the Concrete

After the line cut is completed, position the jackhammer to break the concrete starting from an inside corner of the line-enclosed slab. Put the jackhammer on and let it break the concrete. You don’t need to push down on the jackhammer as its weight and movement are enough to break the concrete. You may need to remove the first few broken pieces out right away to make room for the next pieces to fall off. You will find that after the first piece is broken, the next one comes off so easily.

You may find that the concrete is supported by a wire mesh. You may have to cut these wires using your bolt cutter to free the concrete that is stubbornly attached to these hard metals. Also, most concrete that is subjected to traffic would be reinforced with rebars. In such a case, you may also need to cut these but using a demolition saw.

7. Remove the Concrete Fragments

If the cutting site is inside a garden and you need to protect the plants along the way out onto a hired gravel truck, you would need thick gloves to manually load these concrete pieces into carry-able sacks. For the smaller pieces which would be impractical to pick out one by one, use your shovel to scoop these tiny ones into the sacks. If your hired truck is not yet available, you may arrange the sacks abreast of each other in one area close to the pick-up point.

8. Check the Work Done

If you are not satisfied with the depth of your cutting after the area is initially cleared, you may level the area by using the jackhammer again on protruding and unbroken concrete. Repeat this procedure until you are satisfied.

While it is true that the concrete has been removed after the eighth step, you need to complete your job for your own satisfaction. You are not finished until you have cleaned the site, the power tools and the safety equipment. Restore the items that were displaced temporarily. Remove the protective covering on the plants. Clear the site of dust using damp cloth. Remember not to wet electric-powered tools. Clean the gadgets that are washable with water. When you are done, you are now ready to pack up leaving the site ready for the next activity.

Using Power Tools for Cutting a Concrete Slab

Cutting a concrete slab can be a complex task that requires proper skills and equipment. It isn’t a job where short cuts can be taken. Ideally, it should be done by those who have the proper experience and expertise. Highlighted below are some information and tips in using power tools for cutting a concrete slab.

cutting a concrete slab for road

Tip #1: Choosing the Concrete Cutting Equipment

It all begins with the right tools and accessories. The quickest, easiest and safest tools for this job are power tools that are capable to tackle the job at hand.

The Right Saw

The type of cut you will be making determines which saw to use. If you only need to make small rough cuts, you can do this manually with a sledgehammer and chisel. The much faster and more effective method is to use a circular saw with the right choice of blade.

The Right Concrete Cutting Blades

Quality is the key here. You may find some great prices on some of the blades that can cut through this type of material. You need to determine though, what is the cost per cut. If you are only going to get half the cuts completed before having to replace them, then you are wasting time and money.

Many professionals like to use the diamond blades when cutting a concrete slab. If this isn’t a job you need to do all the time, then you can rent these types of blades. You will likely be charged according to the number of inches used on the blade. Some of the inexpensive blades tend to slow down the cutting process. This is because they only allow for shallow cuts during each pass. With constant use, they can create an odour, fine dust and get really hot. When making the choice to use the diamond blades, you will have to choose the appropriate one.

The dry cutting blades are used when you want to make gradual deeper cuts. The blade won’t heat up, but you will create a lot more dust with a dry cut. You can also choose to use a wet cutting diamond blade. This means you will need to use a saw that is able to distribute the water that the blade needs to operate efficiently. This is a great blade for speed and efficiency as well as in keeping the dust down.

Tip #2: Techniques for Cutting a Concrete Slab

In some areas, there are regulations regarding the depth that you can cut a joint. You need to check this out first. The normal cut is at the minimum ¼ of the thickness of the slab. Keep in mind that the deeper the cut, the bigger the chance of cracking in the control joint. Don’t cut down to the level of the steel reinforcement, which should be in the middle of the slab.

Grooving

You need to determine the best time for making the cut. This is determined by the size of the slab. To help you make a straight cut, draw a chalk line on the concrete slab. Or you can use a 2×4 as your guide. Before the concrete becomes hard, groove the control joints. Use a grooving tool that has a blade capable of cutting through a semi solid concrete.

Tip #3: Proper Placement of Joints

Where you place the joints will depend on the purpose the concrete slab is being used for. Sidewalks do well with joint placement with cuts made the same distance as what the width of the walk is. Large slabs are best done by determining the thickness of the slab then double this in feet.

Tip #4: Cutting Concrete Slabs with a Saw

If you don’t want to take the time to hand groove or the concrete has become too hard for this, you can still complete the job with a saw. The concrete should still look a little damp and dark in colour. You should be able to walk on it. If the concrete slab is fairly small, you can use a heavy duty circular saw, fitted with the proper blade. For larger concrete slab cutting, you may want to use a walk behind concrete saw.

Concrete Cutting

You may be faced with the task of cutting through concrete to get at some faulty plumbing or other repairs needed beneath the concrete. These are normally slab foundations and are far thicker than slabs used for sidewalks and other outdoor venues. For this type of job, you would need to rely on the use of commercial concrete saws.

Other Considerations

Personal safety when cutting a concrete slab using power tools is something that must be made a priority. The proper safety gear must be worn. Keeping the dust under control is another issue. Using power tools with the proper skills to avoid personal injury is a must. You must also be aware of the environment around you when taking on the job of cutting concrete slabs.

Time and money has to be taken into account as well. Purchasing the proper concrete cutting power tools can be expensive. They are not cost-efficient unless they are going to be used on a constant basis. Renting them is equally as expensive and there is the risk of improper use. Make sure that the individual who is going to take on the concrete slab cutting job has the proper skills and training in the use of the power tools.

Looking at a concrete cutting slab job at first appears straightforward. However, there are a lot of potential problems that can arise. If an error is made during the cutting process, correcting them may not be easy. A much better alternative to taking on this job yourself if you are in Melbourne or the surrounding areas would be to bring in the experts like those at MegaSaw.

They have the right equipment for every type of concrete cutting task. They also have the expertise in being able to use the different types of hand saws. These are often needed for hard to get at places or when time is of the essence. Concrete hand sawing requires precision working and takes time to be done properly. You also have to consider the cost factor required for this task. Determine the most cost-effective solution. Will it be either buying this type of equipment yourself and then developing the proper skills to use it or using the alternative of being able to rent such equipment and services from reputable providers like MegaSaw.

How To: Cutting Concrete Blocks

A lot of the times whole concrete blocks will not fit into the place where they are intended to fit. Because of this, you are going to have to cut them down to the appropriate size. There are a few ways in which you can go about cutting these types of blocks. The method that you ultimately choose will likely depend on how smooth or rough you want the cut to be. Also, it is going to largely depend on the type of tools that you happen to have at your disposal. Below we will discuss some of the most frequently used tools for cutting these types of blocks.

Frequently Used Tools:

1. Hammer and Chisel

hammer and chisel

One of the most frequently used tools is the hammer and chisel. In order to utilise this tool effectively, you are going to need to be sure that you have the appropriate safety gear. You will want to wear goggles in order to protect your eyes. You will also need to wear gloves to protect your hands.

Below we will discuss the steps that someone is going to need to take in order to successfully cut concrete blocks with a hammer and chisel.

a.) Mark the layout

The first thing that you are going to have to do is mark the layout of the actual cut that you are going to perform. You will want to make the layout all the way around the actual concrete block by using a straightedge in order to keep the line as straight as possible. You should also use chalk in order to make the line visible enough to see in different lighting conditions.

b.) Safety glasses and gloves

As noted previously, you are going to want to be sure that you have the necessary safety gear. For cutting concrete blocks with a hammer and chisel you will need; gloves, safety glasses and a dust mask to keep dust out of your face and your lungs.

c.) Score the block

You will need to score the blog along the line that you created with the chalk. You will want to do this with the chisel tool, as well as a strong hammer. In order to do it effectively, you need to apply strong and swift blows to the concrete. This will ensure that the concrete is penetrated and that it breaks. You should make a score around 1/8 of an inch deep to start.

d.) Strike

The next thing that you have to do is strike along the actual scored line. You need to use the same chisel and hammer that you used in the previous step. This time, you will need to apply strong and swift hammer blows to the line. If done properly, the block should then break into two different pieces with a rough cut along the line that you had previously scored.

2. Power Saw

power saw

The next tool that you should use is a power saw. This is an excellent tool that is extremely powerful and versatile and you can find at just about any hardware store. If you are in need of efficient, effective, and accurate cuts, this is going to be one of your best options available on the market. Below we will discuss some of the steps that you need to take to ensure that you do it properly.

a.) Choose a circular or power masonry saw

The first thing that you need to do is choose either of the saws mentioned above. You will want to carefully look at each option and consider the pros and cons of each. Consider what you are going to be doing with the saw and what features you care most about. Once you have chosen one, you are then going to want to be sure that you outfit the saw with a masonry or diamond blade according to whichever is appropriate.

3. Safety Materials/Tools

safety gears

The next thing that you are going to need to do in order to ensure that you cut the concrete safely is wear safety glasses, ear protection and a good dust mask. All of these are necessary for the safe operation of a power saw because you are going to have a lot of debris flying around and it is also a very loud machine. These safety essentials are going to help ensure that you do not suffer any type of injury that could have been easily prevented.

a.) Set the measurement

The next thing that you must do is set the measurement of the actual saw blade. This is an important step. This is a step that you must do correctly in order to get an accurate cut. Always figure out how deep you want the cut before actually doing it. You should generally use either 1/4 to 1/2 inch deep of a cut.

b.) Cut around the block

Once you have cut around 1/4 to 1/2 deep, you are then going to want to cut around the entire block. You should adjust your blade so that it will cut 1/4 to 1/2 inch deeper than you previously cut. You will be required to make a number of passes through the block until you have actually cut through the entire block. In this case a power saw will be able to produce a much cleaner and accurate cut than chiseling can produce.

4. Block Splitter

concrete block cutting service

A block splitter is another type of tool that you could use in order to cut concrete. You can use this type of tool if you want a very powerful machine that will get the job done fast. Below we will discuss some of the things that you are going to need to do in order to successfully use this type of tool for block cutting.

a.) Rent or purchase a concrete block splitter

Most people are likely to need to rent this type of tool from their local hardware or tool rental store. This is likely to be the case because these tools are fairly expensive. Therefore, it is not really in your best financial interest to invest in one if it isn’t going to be used frequently.

b.) Place the concrete

The next thing that you are going to want to do is place the concrete in the right location. You will need to ensure that the concrete is placed on the platform that is directly located beneath the actual blade for cutting. This will ensure that the blade will slice into the block when it is cutting. In order to ensure an accurate cut, you need to be sure that the block is placed in the exact location of where you want the cut to be made.

c.) Secure the block

The next step involves securing the actual block in place by spinning the wheel that is used for tightening. You should spin the wheel in a clockwise direction in order to tighten it.

d.) Pull the level

The next step involves pulling the splitting level downward and applying enough pressure on the actual level in order to effectively split the concrete. You will know you did this correctly if the tool effectively splits the concrete. The cut is likely to be very precise in terms of cutting it where it was supposed to be cut. However, the cut is likely to be just as jagged as a cut that is made by hand with a chisel.

In order to effectively get your concrete cut in a professional way, you will likely need to hire the job out to a third party. Cutting concrete is something that takes a lot of power and experience to do effectively. For this reason, you are going to want to hire an experienced team that has access to the latest and greatest tools and machinery. This will ensure that you find someone that is going to be able to really deliver the best possible results on your job.

You will also want to ensure that the job is completed on time. Nothing is worse than hiring a company only to see them miss their deadline. In order to find a reputable company in this industry, you need to ensure that you do the necessary research in order to find one that has a good and solid reputation within the industry. You will also want a company with competitive rates in order to get the job done efficiently.

How to Control Dust When Cutting Concrete

Construction workers are exposed to dust when dealing with concrete that might be harmful to their health. The three main types of construction dust are:

Silica dust

Usually present in sand, granite or sandstone, Silica is a natural mineral. It’s also found in other materials used for construction such as mortar or concrete. During the cutting, grinding or drilling process, the mineral is broken into fine dust which is referred to as silica dust.

Non-silica dust

Although silica is the main component of most materials used for construction, there are a few that don’t contain the product or the content is very little. These compounds include limestone, cement and marble. There is a chance that these compounds could get mixed with those containing silica so in the end, the fine dust contains silica.

Wood dust

During construction, wooden bars may be used for support for other users. The wood might either be used as softwood or hardwood depending on the type of construction. There are also wood-based compounds often used during the construction process. As such, when the wood is cut using saws, the wood dust is likely to cause harm to the construction workers if preventive measures are not in place.

Health Effects

If you’re not properly protected when handling these types of dust, you need to know the type of damage they are likely to cause. There are many construction workers who have fallen ill due to lung cancer, silicosis, asthma or COPD (chronic obstructive pulmonary disease).

For health risks such as silicosis, a form of lung disease, there is a chance that a few construction workers might experience the side effects later on. However, for those without proper protection, the symptoms set in when the contractor breathes in too much silica dust. When diagnosed at an advanced stage, silicosis is hard to treat but can be managed effectively.

There are recent studies that have estimated that silica dust has resulted in the death of over 500 construction workers each year. Also, COPD has resulted in the death of 4000 construction workers every year. Anyone who works in construction falls into the risk category because of the concrete dust they breathe in when working.

Construction Tasks that Create the most Dust

If you’re a construction worker, you’re likely to experience more levels of dust during the following occasions;

  • When using construction equipment that operate using high energy such as wall chasers, cut-off saws, grit blasters or grinders, which produce lots of concrete dust within the shortest time possible.
  • When clearing the dust using dry sweeping rather than wet brushing or vacuuming, you’re likely to inhale more dust.
  • Also, if you’re working in an enclosed construction space rather than an open air one, the concrete dust is trapped in the space forcing you to inhale it.
  • If you take longer when handling concrete cutting tasks, you will inhale more dust than the people who work for shorter times.

How to Control Exposure to Concrete Dust

dust from cutting concrete

1. Legal requirements

There are workplace regulations in place to prevent exposure to any dust during construction. Other than wearing protective clothing or equipment, there should be control measures in place to reduce the amount of dust. One of the most effective ways to do so is capturing the concrete dust at the source before it spreads into the air. Also, there are environmental regulations in place to prevent dust emissions or to control their contamination using the best possible means.

2. Wet control methods

Concrete cutting saws that are powered by compressed air or combustion engines might use wet systems to prevent further contamination of dust. However, it’s impractical to use these systems on electrical saws. Water is sprayed into the rotating disk used for cutting concrete to reduce emissions. Water can be supplied using a pressurised tank which is portable or from the water mains.

Portable pressurised tanks are supplied by many manufacturers of concrete cutting saws. It’s a simple bottle (made out of polypropylene) that contains at least eight litres of water. Using a narrow tube, the bottle is attached to two jets on each side of the guard. To control the water supply, there is a valve attached to the container. When the construction worker pressurises the tank using his hand, the water is released.

To guarantee dust suppression, the minimum rate of water flow should be about half a litre each minute. Therefore, rates lower than that will ultimately reduce overall performance. On the other hand, higher rates will not guarantee proper suppression of concrete dust rather the portable water tank will need to be refilled frequently.

To maintain the proper rate of water flow, the portable tank should be pressurised regularly. This is the most preferable method since it’s flexible to carry around the site as long as there is a water source for any refills required. On the other hand, when using the water system from the mains, the water flows through the hose to the water jets to allow for dust suppression when cutting concrete.

3. Personal protective measures

When using the wet systems or vacuuming to suppress the dust produced when cutting concrete, there are many things that can go wrong. Therefore, when this happens, it’s important to have some protective equipment such as masks to prevent further inhalation of dust. There are different types of masks for different tasks so it’s important to consult with your employer to get the best mask for the task in hand.

Note that, wearing masks or any other protective gear alone will not provide the protection you need. This is because:

  • There are many tasks that can produce too much dust which clogs the filter making it hard to breathe.
  • A mask only protects the wearer alone. Other individuals at the construction site are at risk of inhaling dangerous dust.
  • There is a chance that you might choose the wrong mask which means that you’re not completely protected.

Therefore, regardless of whether you are wearing a mask or not, it’s important to include all the other protective measures to ensure you have the best chance of staying safe when working in this kind of environment.

A Step By Step Approach in Concrete Cutting Leads to Greater Safety

The requirement to cut concrete is not something that comes up very often, and is an activity that is carried out normally only by builders or contractors. When such needs do come up, the right equipment to use is a concrete saw.

Concrete saws have the power and blades to cut through very dense materials and besides concrete, may even be used to cut stone or tile. Regular cutting tools will find it difficult to deal with these materials. Most concrete saws are power tools and will use pneumatic, hydraulic, electricity or gasoline-powered engines for the huge strength requirement of cutting through concrete. Concrete saws are available in many different sizes and can be hand held or table mounted, or may even have chain saws that facilitate very large and complex cuts. Some machines may be large enough to walk behind and guide while they perform the cutting operations.

Saw blades need to run very fast in order to cut through concrete, and this causes a lot of friction and heat. Most machines use water or other cooling substances to cool the blade, which can otherwise cause it to get damaged. A common accident while using concrete cutters occurs when blades break off due to the heat. These blades have tips made of hard substances like titanium, so that they can stand the constant abrasion caused by the cutting process.

Check your Blades

Before you start any concrete cutting, it is necessary to check the condition of the blades and replace them if they are worn out or have any segments missing. The core blade must not have any cracks. The blades must fit correctly and firmly into the blade holder. The saw should be run to ensure that the blade is properly aligned and there are no distortions in the movement. Raise the blade from the working surface before you do this, as otherwise you may find that you have started cuts you do not want to make.

If you are using gasoline powered engines, make sure that you have enough fuel so that the operation is not interrupted. Ensure that you put on all the necessary safety gear like goggles, dust masks, boots, ear protection and other gear. Make sure the blade faces away from you before you start the motor, and that you have firm control over the machine. Do not lower the blade onto the surface to be cut, unless the blade has reached its optimum speed.

Mark the cut that you want to make by using chalk or paint, so that it is visible to you at all times, while the sawing operation is in progress. Initially, before the cut commences, the surface of the concrete must be completely dry. Now you can lower the blade onto the surface that you want to cut, and make sure it is aligned to the cut line. There will be a lot of dust generated when you first start the cutting operation and also afterwards, and you must be prepared for this. Very large operations may use water or oil to cool the blade and also control the dust.

Tight Grip

 

cutting concrete road using

The equipment must always be grasped firmly and pressure exerted on the cut, so that it bites into the concrete and progresses further. Constantly check on whether the cut is proceeding on the required alignment by raising the blade and examining the cut, after you clear it of the dust with a blower or water. All saws will have guards and you must never raise this, without stopping the engine or switching off the power. A concrete saw is just a sturdier version of any cutting tool, and all the precautions you need when you operate smaller cutting tools, like wood saws, have to be followed even more stringently. Some saws allow you to adjust cutting depths with the simple use of adjustable flanges which need to be set to the correct depth. These flanges are normally mounted on either side of the saw, and rest on the surface being cut, to serve as a guide to the cutting depth.

Once you have completed the cutting operation or need to stop work for the day, raise the saw blade before you cut off power or stop the engine. Allow the blades to cool down and examine them for any damage that may need to be rectified or corrected. Cutting of concrete surfaces must only be taken up after the surface is cleared of all loose material, as this can fly off the fast operating saw and cause injury to others. It always makes sense to ensure that large cutting operations are properly fenced off and unauthorized personnel kept away from the cutting site.

Tips on Safe and Efficient Concrete Cutting

Concrete construction frequently requires cutting into cured concrete. This is a specialised job that requires quality equipment and well-trained workers. As with many skills in the construction industry, concrete cutting has a lot of specialised safety considerations. Here’s a brief overview:

How concrete gets cut?

Concrete cutting is a significant part of construction work in both commercial and residential applications. It’s also commonly required in civil engineering projects and road work.

Cutting concrete is a job for heavy-duty power tools. Hand-held concrete cut-off saws exist, but the most common tool for significant cutting jobs is a walk-behind saw. Today, most concrete saws use diamond blades, although abrasive wheels are a less-common option.

Concrete sawing can be done either “dry” or “wet,” with wet sawing making up the majority of the work. Water helps to cool the saw blade and reduces the impact of dust created by cutting (see below).

Basics About Equipment

Matching the cutting gear to the job is extremely important if work is to be done safely and efficiently. Manufacturer’s recommendations provided by both the makers of the saw and the makers of the blade should be followed at all times.

Different blades are made for different materials, and also for different cutting depths. The composition of the concrete to be cut – aggregate fill, reinforcement, and density – must be ascertained before picking the right blade to do the job. As covered in greater depth below, it’s important to ensure that the saw’s blade is in good working order before starting to cut. This is a skill that’s essential for any trained concrete cutter.

Safety Gear

Appropriate clothing must be worn by all workers using a concrete saw. Exposed skin must be avoided if at all possible. Eye protection is a must, as is hearing protection. (Concrete saws are extremely noisy while operating.) For road work, a high-visibility vest is an essential part of the concrete cutter’s working outfit. As with all power tools, concrete saws should only be operated in properly-posted environments with adequate first aid supplies within easy access.

Precautionary Checks

Every concrete saw has a full start-up checklist to run through prior to cutting. It’s important for concrete cutters to be thoroughly familiar with the exact equipment they’re using and to make each appropriate check before starting operations.

For all concrete saws, verifying the condition of the diamond blade is a must. Cutters must check for any cracks, missing blade segments or other signs of wear and remove blades that are in any way damaged. Experienced cutters also know how to look for signs of discoloration (commonly blue-black) that can indicate heat stress and a possibly weakened blade.

Safe Operations

Patience and certainty are very valuable traits for concrete cutters. Despite their amazing cutting power, diamond saw blades are surprisingly fragile. Forcing them beyond their normal operating conditions can easily result in damage or injury.

In most concrete cutting jobs, cuts should be laid out with a string or chalk line in advance and lined out for the cutter with a clearly-visible wooden board. It should be easy for him to follow a straight line in order to minimise blade wear due to twisting and turning.

“Pilot” cuts are frequently employed to make concrete cutting easier; these are shallow (usually quarter-inch) cuts laid out at the start of a job to identify where deeper cuts are needed. When cutting begins in earnest, cutters will let the tool do the work. The blade should be allowed to settle to the proper cutting depth on its own and then moved at its own pace.

Dust Control

Aside from the threat of physical injury, the most important safety concern in concrete cutting is probably dust control. Most concrete contains plenty of crystalline silica, and the act of cutting it creates respirable crystalline silica, commonly known as RCS.

RCS is a severe irritant and can be so fine as to be almost invisible. Water-assisted concrete cutting reduces the production of dust but does not eliminate it. Most concrete saws except the smallest hand-held models have an on-board ventilation system to further reduce the creation of airborne RCS dust. Concrete cutters (both saw operators and assistants) should wear respirators at all times.

While concrete cutting is a complex, skilled job with a lot of potential dangers, it’s not hard for properly-trained cutters to stay safe while they work. As in many professions, a level-headed concrete cutter is one who always keeps safety in mind. With that mindful attitude, cutters can easily get their jobs done without putting themselves or their co-workers at risk.

Do You Need Concrete Cutting and Repairs? Heed These Warning Signs

A hazard is defined as any change in vertical over quarter of an inch or greater than that at any crack or joint. Since Australian authorities demand every region to comply, it is the duty of MegaSaw to manage the concrete cutting and repair services professionally. We are experts in cutting and drilling services in Australia. We can handle both home and commercial concrete structures that require maintenance and replacements regularly. Remember, regular maintenance is better than to wait and replace those broken structures.

Peter H. Emmons of the Structural Group and Alexander M. Vaysburd, who is a concrete expert for over 30 years have provided this detailed summary about concrete repair and maintenance. The points they highlight are as follows.

Concrete Behaviour

This is where any concrete construction is expected to have a lifespan according to the quality and mixture used during the making. Concrete behaves in reaction to an action. The forces of nature such as weather and human activity determine its life. Rain and cold weather causes contraction, while warm environment causes it to expand. Over the duration of time, concrete expands and contract daily and it becomes weak. It then cracks and may divide and break completely. This observation suggests that replacing or regular repair of concrete construction is necessary.

Evaluating Concrete Problems

Concrete evaluation is necessary all throughout the making process. The durability and strength to endure effects is measured during that time. Concrete experts can tell the strength of a concrete structure even after ten years depending on how it was manufactured. The whole process entails measuring the ratio components of the products used to make the concrete.

Surface Repair

Professionals have a way of repairing; it is either by replacing parts or the entire affected concrete area. It is necessary to be carried out as it may affect the other parts if not attended to promptly. For example, a public walking surface may crack, and if not repaired, the area extends and becomes larger with time. Once noticed, the experts use equipment such as a handheld saw. This is a special type of saw that cuts through cracked concrete to avoid the spread. Then the area is filled with fresh concrete material and joined to the older remaining part.

Stabilisation and Strengthening

This is where concrete is enhanced by adding other materials during construction. They help to compact the entire part together until it dries. This builds a stable wall or surface that is resistant to breakage due to use of heavy materials on the surface. It makes the surface stronger and long lasting such that it takes many years serving before it is affected by adverse weather conditions.

The final stage after building a strong and stable concrete surface is to protect it. An application of another layer will serve as a protection. This ensures that the underlying concrete surface is not exposed. Most of the pressure is on the protected area. This protective function is also known to prevent breakage. It should be resistant to the weather, can absorb great pressure and cannot be peeled off easily.

Concrete cutting and repair is necessary when the surface is in specific conditions. This includes residual areas, home and commercial places. The following conditions are suitable time to carry out the concrete maintenance practice:

1. When the Surface Has a Crack

There are times when concrete becomes weak and cracks. This peels off the top part and exposes the inner layer. It can injure any road or floor user. That is why it is a risk residing in an old and under maintained apartment. Small cracks may seem minor to avoid, but it is through them that water and other objects will get into the concrete.

2. Seepage Conditions

As said above, cracked surface will allow flowing water in, small objects can cause enlargements of the crack plus the inner part is exposed to adverse weather.

3. Leaking Walls

Leaking walls, for instance, those in the kitchens or those in the bathrooms should never be ignored. They are the major cause of weakness in any structure. Water, especially rain has acid in it that corrodes the concrete and makes it weak. Regular leaking leaves weak lines in the surface and the whole structure may collapse over time.

4. Scaling

This is where the measurements are not aligned to as required and you find some are side higher than others. If this happens to a footpath is can cause injuries to pedestrians and accidents which could have been avoided.

5. Discolouration

A discoloured concrete surface is as ugly as an old, unpainted one. Leaking surface will wash away the original colour of the surface. Whether painted or not, this will leave a semi-permanent mark. Solving this problem is an extra cost incurred. If it was better done from the beginning, it would have cost less.

6. Curling

How to Avoid or Treat the Above-Mentioned Conditions

One of the steps a contractor has to do is to grind the floor and the concrete surface. This is done by use of a heavy machine that is made to grind concrete. It vibrates and compacts the surface while still wet. By the time it dries, it is kept cool by covering the surface with a cold material of water material.

Removal and Demolition of the Affected Part

This is where concrete removers extract the entire affected area and separates it from the intact part. It is perfectly done by extending the affected part to some extent in the stable part. This is to avoid risks of unseeing penetration of the affected area.

The other step is to carry out concrete sawing and drilling. Drilling removes the affected part, and also the vibration serves to remove any remaining bad part on the surface. This leaves a strong well-cut and levelled surface unlike, the removed part.

Another thing to do to avoid concrete failure is to apply the masonry tiles. This is done as a topping after a perfect surface is ready. The tiles give protection to the floor and pavement in the commercial building. This serves more in the commercial areas where heavy object can be dragged causing floor surface damage. Hardscape and tile saw are used to shape and fit tiles to the surface perfectly to ensure no spaces are left to chance.

Dust Extraction

There are special sets of equipment that are used to extract dust from the wall or floor surface. Most of these units are vacuum operated, and they can suck even the minor dust particles. A well-dusted surface lasts longer because there are no chances of dirt penetration and accumulation between the tiles.

Concrete Floor Polishing

This is done during and after the surface is dry. It is done in two parts. To leave a surface that has the set standards is to remove the entire surface and to rebuild it a fresh. But the MegaSaw experts give you an alternative by restructuring the surface then polishing if. It saves time and space. On sidewalks, a well-done repair or restructuring is better as compare to another concrete surface as it is less destructive.

Warning Signs that Show that Concrete Cutting and Repair are Required

Incorrect alignment

The surface should always be aligned to each other and in most cases straight. When you find that some or the entire surface has upwards and downwards movements, it should be an alarm that it requires repair and other maintenance measures. The surface should be attended to before it becomes worse to the extent of falling apart and leaving part of it exposed. At a later stage, pot holes can emerge. Cutting and installing a new concrete will take less time to align it.

Discolouration

A discoloured concrete region shows that there is a leakage underneath that is not observable from the top. In that case, it should be cut, dug and corrected. Filling and polishing the area will easily restore it to the normal state.

Extreme Roughness

This sign shows wearing off, and the surface will not be serving much longer. Anytime, it will progress to peeling off stage and eventually pot holes. A complete new structure is required to restore it and align it to the rest of the surface.

After rainfall and there is stagnant water in parts of the surface after other parts drain

This too shows that there is a problem with the alignment of the surface. At MegaSaw, concrete cutting and repair service of such parts is a simple task. With the use of hand machines, we can drill even your house floor and leave the drainage moving to one direction as required. For the commercial houses, much bigger and faster tools are used. This is to ensure that your business premises continue as scheduled.

Reasons to Hire a Professional Concrete Cutting Team for Your Project

Concrete cutting within both domestic and commercial settings requires a certain level of professionalism that is hard to attain without requisite skills in place. This is one of the major reasons for hiring a professional concrete cutting team. Let’s look at the top ten reasons for choosing a professional team over amateurs.

Concrete cutting is a task that requires meticulous attention to detail, and where a professional is going to safely and efficiently cut through concrete. The best professional concrete cutting services are those able to do this task as efficiently as possible while ensuring that all risks are minimised as these can be among the biggest hurdles along the way.

1. Efficient

Efficiency is crucial as it helps to reduce the amount of wasted time while you are waiting for the project to move along. Meanwhile, a bad concrete cutting job company will more likely bring the entire project to a halt. For this reason, it is imperative to work with competent companies.

2. Quick

The results always have to be as quick as possible for those who want the best and want to get moving along with their project. There are far too many individuals who do not understand this until it is too late, and their entire project has stopped moving along. The best service is always quick but still can maintain the highest standards to ensure quality results.

3. Proven

A proven track record speaks volumes about the quality of a professional concrete cutting service. It all comes down to choosing the right contractor who can deliver on their promise.

4. Safe

Safety tools When Cutting Concrete

Imagine having a contractor come in and start cutting concrete only to notice that the job isn’t safely done. This is one of the biggest issues clients fail to see until too late. Is the job being done as safe as it should be? With a concrete job, this is one of the biggest concerns, and those who do not pay attention to this will regret it down the road.

5. Courteous

This is something most people do not look for until it is too late. It comes down to considering the person as a whole. Going with any contractor is a big mistake because you have to judge how they are as a person. If an individual is not courteous, then he is not worth your time or your money.

6. Organised

This is given, but the best professional services are always ensure that an individual is getting an organised professional who knows what the best approach is. They won’t fiddle around in order to find the right solution because they already have a plan in place that is going to do the trick as required. This is the best type of service and the only one you should be going with.

7. Have Plan B in Place

This is another factor that is a part of life and can come under the concept of being organised. There are many individuals who assume that the contractor knows what the best approach is, but there are going to be moments where things are not as simple as they should be. This is where a professional will come in handy because they always have a plan B in place, which can be a lifesaver in the long run. It all comes down to knowing that anything can happen, and most professionals will have enough experience to deal with these problems head on.

8. Understanding

Let’s imagine that the concrete cutting project is taking place, and all of a sudden an issue arises that is hard to ignore. Let’s imagine that you want to change something that is being done, and this is spoken about halfway. True professionals can understand and realise that their client has a specific requirement. And understanding professionals will make sure that you get your way.

9. Meticulous

Concrete cutting can often come down to those important details that can make or break the entire process that is in place. Those who do not work with meticulous professionals will be left wanting, and that is not a good place to be in. A meticulous professional always know that being attentive to every detail will make the concrete cutting experience flawless as it should be in this day and age. Anything short of this is going to be mediocre.

10. Patient

The final reason for going with professional concrete cutting services comes down to how patient they can be when you want them to be. This means, let’s assume that you have specific requests that have to be met, only a patient professional will be able to deal with them and present a solution that works.

Secrets to Hiring the Best Concrete Cutting Solution Provider

If you have concreted areas on your property that need to be removed or remodelled, then you will need a qualified concrete cutting solution provider. Most providers are experts in breaking down large chunks of concrete into manageable pieces. But prior to hiring a certain company for this task, you need to consider a few things. Be sure to hire someone who can accomplish the task for you safely and of the best quality.

Search Through the Internet

There are likely various contractors working in your city who offer these services. You can begin your search by looking online for those near you. Look at the top several results in your search. Check out if their sites provide their contractors’ contact number for your state. You do not want someone who does not have the proper qualifications for your State, right? So, always go for the best.

Look for Bonded/Insured Company

In addition, you should look to see if the company or contractor is bonded and insured. Both of these are essential to protect you financially, should anything go wrong. If the company does not have insurance, you can be liable for damages. Your homeowners insurance may or may not cover it. If they do, it is likely that your rates will go up due to the claim. They should also be bonded in case of theft or other forms of liability that the company may be responsible for.

Read Customers’ Reviews

Once you have a list of several potential concrete cutting solution providers, you need to research a range of consumer review websites. This is to find out about the experiences of others with the company. It is vital that you make certain these are legitimate consumer review sites. Be aware that some sites may be sponsored by these companies or their competitors. If contractors or their affiliates advertise on the page or pay to have it supported, there is a high likelihood that negative reviews will be removed by these sponsors.

Get in Touch & Inquire

Once you have confirmed those with a good reputation, contact the companies. Make a request for a representative to come over your property and provide you with a written estimate. Let them know that you will be contacting other businesses as well. Ask that the quote be broken down so that each service that is needed is clearly listed and accounted for. You should also ask about any additional costs that may be incurred as a result.

Consider Proper Behaviour

If contractors are already at your home, pay attention and take note of their professional demeanour. Reputable contractors should be in proper company attire and present themselves as such. Is their shirt tucked in? Are they wearing a name tag or badge? What is your gut feeling regarding their behaviour? Remember that you will be paying them for the services they will provide. So, do not settle for anything less than a pro.

At this point, you should be able to make a decision based on all of the information you have gathered. This is the best way to hire a concrete cutting solution provider who will get the job perfectly and satisfactorily done for you.
