Why Are Diamonds Used For Cutting Concrete?

Concrete is an incredibly tough material to cut through. It only makes sense then that the material used for concrete cutting is incredibly tough as well. Typically, this material is a diamond cutting blade. 

Diamond cutting blades are the primary go-to when it comes to cutting concrete and even reinforced concrete. Projects, whether they are large or small, make use of diamond saw blades that are tipped with industrial diamonds to ensure an efficient concrete cutting process. 

Why else are diamonds used for cutting concrete? If you’d like to learn more about this, please feel free to continue reading our article below.

Why Use Diamonds To Cut Concrete?

Diamond saw blades are made of a circular steel disk with segments containing a mixture of diamonds and metal bond powders on the outer edges of the blade. The diamonds and metal bond powders are pressed and heated, tailor-made to the specific cutting application.

Industrial-grade diamonds are incredibly hard substances. When used properly, diamond blades can easily cut through any type of material. Additionally, they are capable of dispersing or transferring heat well, which means that they can withstand high temperatures from large amounts of friction. 

While diamonds are one of the hardest substances on the planet, there are plenty of other reasons why you would use diamonds to cut concrete. Some of these reasons include the following:

1). Speed

Diamond saw blades are incredibly efficient because they can quickly create precise cuts. There are various designs and models of diamond saw blades available. Each model has its own edge for carrying out the job fast while still remaining precise.

For example, there are turbo blades that have a continuous outer rim and a serrated edge. This allows the diamond blade to sustain high speeds and create precise cuts.

2). Durability

Durability is a stand-out characteristic of diamond saw blades. Compared to other blades, they are incredibly durable because they have a circular steel disk with segments situated on the outer edge.

These segments are a mixture of diamonds and metal bond powder that are fused under high heat and pressure. This helps increase the longevity and durability of the diamond saw blade. 

Additionally, because diamonds are naturally the strongest substance on earth, they can last for years without losing their performance. Because of this, diamond blades are also cost-effective concrete cutting tools.

3). Precise Cutting

As previously mentioned, diamond saw blades can create incredibly precise cuts. One reason for this is that diamond saw blades don’t generate a lot of vibration which means that the cutter can position the blade at precise locations. 

Aside from precise cuts, diamond saw blades can create smooth cuts due to the diamond’s high-performance ability. A smooth cut means that the concrete structure will not be as strained compared to when other concrete cutting blades are used.

Additionally, low vibration is another factor in the prevention of increased strain on concrete during the concrete cutting process.

4). Comfortability

Using diamond saw blades is quite comfortable. You’ll be able to not only create a cut without creating as much chipping and breakages, but the blade will produce significantly less noise in relation to other concrete cutting blades. Additionally, diamond saw blades can also remove the excess slurry and reduce dust generation during the cutting process. With this, diamond saw blades are definitely a more comfortable option to use.

Summary

Diamond saw blades are the best concrete cutting blades to choose from. Not only are diamonds, synthetic or natural, the hardest material, but they are infused strategically onto concrete cutting blades to deliver speed, durability, precision, and comfortability. 

Additionally, diamond saw blades are specifically made and designed for different concrete applications so that they will best deliver all the aforementioned advantages. With that, diamond saw blades are the best go-to in the concrete cutting industry over any other type of concrete cutting blades.

How To Select The Best Concrete Cutting Tool For Your Job

Choosing the right concrete cutting tool for your project can be quite challenging given the wide array of tools out there. However, there are a couple of steps you can follow to determine which tool is best suited for your concrete cutting project.

If you would like to learn more about how to select the best concrete cutting tool for your job, here are a few steps to help get you started:

1). Know The Different Types Of Concrete

There are various types of concrete, and the type you’re working with will determine what concrete cutting tool you should use. For example, if your project entails that you work on a small area of concrete, a handheld cutting saw is your best bet. Meanwhile, for cutting jobs that work on bigger areas of concrete, you can consider tools such as concrete saws, core drilling, wire concrete saws, etc.

Choosing the right concrete saw should align with the kind of material you plan to cut. It is important to do research on this beforehand to avoid unnecessary time and energy spent on cutting concrete with an incompatible tool. 

How Select Best Concrete Cutting Tool For Job

2). Know The Different Types Of Concrete Saws

Each concrete saw comes with its own unique functions and features. Therefore, familiarising yourself with each can help you determine if they will be useful for your project. Some examples of concrete saws include the following:

  • Hand Saws. Hand saws are the smallest concrete saws available and can be used to slice concrete, brick walls, and other masonry. They are also lightweight and portable, often used for cutting concrete to install HVAC equipment. 
  • Walk-Behind Concrete Saw. These are conventional concrete saws that are heavier and larger than most concrete saws. They are equipped with high horsepower and can cut concrete extremely fast. 
  • Wall Saw. Wall saws are commonly used to create openings for walls, windows, ventilation ducts, doors, and other similar vertical structures. Mounting it on a wall with a track-mounted system can create clean, precise, and accurate cuts.
  • Wire Saw. Wire saws are known to be cost-effective, flexible, and good at reducing wastage. They are often used for projects that handle large amounts of concrete, capable of accomplishing work no matter how big the concrete area is.
  • Core Drills. Core drills are exceptional at punching through concrete surfaces. They can create cuts of all sizes and can accomplish this accurately.

3). Ensure Power Requirements And Maintenance Are Manageable

Every concrete saw has a power requirement. For example, some saws are electrically powered, while other saws are gas-powered or battery-powered. Understanding these requirements and whether they can be delivered in the project is important in the tool selection process. After all, if you can’t meet these power requirements, you won’t be able to use the concrete cutting tool.

The environment in which your project will be carried out can also be a factor in this step. For example, if you are working in an enclosed area, you might want to opt for an electric concrete saw because it is less noisy, lightweight, and easy to use. They also do not emit fumes or fire hazards which are much more detrimental indoors. 

Meanwhile, gas-powered concrete saws are suited for outdoor environments such as cutting asphalt. Since it does not require electricity, it is suitable for dry cutting and is known to be very durable. 

Maintenance is an important factor in this step. You must ensure that you can maintain the machine which you can do by having operators around who have the necessary knowledge when it comes to maintaining concrete saws.

10 Helpful Tips For Efficient Concrete Cutting

Are you relatively new to concrete cutting? Do you need a few tips and tricks to help you get the best results? Luckily for you, this article provides some tips to give you all the help you’ve been looking for!

Concrete cutting is a dangerous job, so there are a few precautionary measures that you must keep in mind when cutting concrete. All of these measures should be carefully considered before carrying out the job. 

Please keep reading below to learn about our 10 most helpful tips for efficient concrete cutting.

1). Choose The Right Concrete Cutting Saw For The Job

There are multiple varieties of concrete cutting saws, and picking the right one depends on the project at hand. For example, if your project requires the cleanest and most precise cuts, a diamond saw maybe your best choice. 

If your project requires large-scale concrete cutting, a walk-behind saw may be the best option. If your project intends to make sharp cuts in reinforced concrete or create clean corners, a handheld saw might be best. As such, make sure you know what cuts your project requires and what tools can deliver these cuts.

2). Use A Wet Blade To Control Dust

If your project requires cutting concrete in indoor areas, reducing dust is of utmost importance to prevent health and safety hazards. Wet concrete cutting is the perfect solution for dust reduction by dampening dust to prevent its transmission through the air. However, make sure to choose wet saws for the project, and ensure that there is a water source handy.

10 Helpful Tips Efficient Concrete Cutting

3). Check The Amount Of Water 

Make sure to check the amount of water that is flowing into the concrete area you are cutting. Too much water can force the blade out of control and slurries could flood the place. If there isn’t enough water, you may end up wearing out the diamond blade quicker. 

4). Be Gentle

Don’t push the blade too hard into the cement when cutting the edge. Rather, allow the saw to cut on its own as you cut through the concrete. If you use too much pressure, the cement cutting process can actually slow down. The blade will also wear out a lot quicker. 

5). Work With Trained Operators

If you aren’t alone and are working with other people using a concrete saw, make sure that they are trained properly. This is to avoid deadly, dangerous, and expensive mistakes from occurring from people who aren’t skilled or trained enough to safely handle concrete cutting saws. 

6). Check For Possible Hazards

Before cutting, check the worksite and locate possible gas, water, and electrical lines. If there are plumbing and cables, ensure they are disconnected from the mains before cutting concrete. You should also check if there are steel reinforcing bars in the concrete and whether its removal will have an impact on the structure’s stability.

7). Keep A Spare Concrete Saw On Hand

You can never go wrong with having an extra concrete saw in good working condition on hand. This will be helpful in the event that your current concrete cutting saw suddenly breaks down or is damaged. 

8). Have A Few Varieties Of Blades

One blade won’t always do all the work, so having a selection of blades can help match the different concrete cutting phases of the project. These extra blades may even act as substitutes for blades that have broken or are worn down.

10 Helpful Tips Efficient Concrete Cutting

9). Cut A Test Area

Before you use a diamond blade to create precise cuts, try testing it out on an abrasive or inconspicuous area of the concrete. This can help wear out or remove the protecting coating on the blade so that you can create cleaner and thinner cuts. 

10). Inspect The Cement Blade

Don’t make the mistake of using a dull blade. Make sure the blades are in optimal working condition to prevent dangerous accidents from occurring and to give you the best results.

Final Thoughts

Concrete cutting can be tough, but there are multiple ways that you can carry out a safe yet efficient concrete cutting job. With these 10 helpful tips, you can be sure to carry out a concrete cutting project easily, safely, and cost-effectively.

Do’s And Dont’s Of Concrete Cutting

Concrete cutting is no easy task. There can be a lot of hazards associated with it if you don’t take the necessary precautionary steps. Therefore, before cutting concrete, it is important to be aware not only of what to do but also what not to do as well.

If you would like to learn more about the do’s and the dont’s of concrete cutting, feel free to continue reading our article below.

The Do’s Of Concrete Cutting

While there are some mistakes that you can potentially make during the concrete cutting process, there are also a few things you need to get right when cutting concrete. These include the following:

1). Do wear protective gear

Regardless of what type of construction job you are carrying out, it is always important to wear the right protective gear. Some of these items include protective glasses, rubber boots, masks or ventilators, long-sleeves and pants and of course, earplugs/earmuffs.

Do's Dont's Concrete Cutting

2). Do take it slow

Don’t rush a concrete cutting job. Using a concrete saw properly means slow, delicate work that can take hours to accomplish. For best results, it’s best to create several shallow passes when cutting concrete instead of making one deep cut on the first try. If you cut too deep and too fast, you can damage your concrete saw blade and cause your equipment to overheat.

3). Do create proper water flow

Most saws used to cut concrete are wet saws, which means they require a flow of water in order to create precise cuts and mitigate the amount of dust created during the cutting process. While a wet saw is the best saw to use when cutting concrete, it is critical that you have a good flow of water and everything is hooked up properly. Never use a dry saw blade with a wet saw machine.

The Dont’s Of Concrete Cutting

Before cutting concrete, it is important to know what not to do in order to avoid safety hazards and accidents. Here are a few things not to do when cutting concrete:

1). Don’t use damaged equipment

Using damaged equipment is incredibly dangerous and will pose severe safety hazards. Damaged blades will also not be able to create effective cuts. Before cutting, make sure to thoroughly inspect your blade and ensure it is not cracked or missing a tooth. Use a fresh and sharp blade if your current blade is damaged. Make sure to keep the blade guard down before cutting.

2). Don’t work in a poorly ventilated area

Working in a poorly ventilated area can be very toxic especially since most concrete saws that run on gasoline or diesel will create harmful fumes. Fumes and the combination of large amounts of dust will be very toxic if you are not working in an open space.

Do's Dont's Concrete Cutting

If you are carrying out a construction project that has been roofed and framed, make sure to wear a mask and have fans around to circulate fresh air and push away dust. For enclosed sites, try to open as many windows as you can and use the fans to keep airflow consistent.

3). Don’t work without a safe lifting method

Concrete cutters can be very heavy, so you will need to have a lifting and lowering method in order to protect your legs and lower back. If necessary, you can wear a back harness and brace to help keep you steady when you lift and cut concrete, most especially if you are cutting the side of a concrete wall.

Summary

In concrete cutting, there are a few must-do’s that you should perform in order to remain safe during the process: do wear protective gear, do take it slow, and do make sure you have good water flow. Meanwhile, there are certain mistakes that you must avoid in order to prevent safety risks and hazards: don’t use a damaged blade, don’t work in a poorly ventilated area, and don’t work without a safe lifting method.

How To Cut A Trench In A Concrete Slab?

While you may have your reasons for cutting a trench in a concrete slab, this job can often seem daunting and intimidating. However, cutting a trench in a concrete slab – like any concrete cutting job – requires the right equipment, technique, and of course, the proper safety precautions.

So how can one actually cut a trench in a concrete slab? Worry not, because we’re here to discuss everything you need to know! If you would like to learn more about this, feel free to explore our article below.

Required Materials And Equipment 

Depending on the size of your project, there is certain equipment that you will need in order to cut a trench in a concrete slab. 

For example, if you have a small project where you plan to cut concrete slabs less than 6”, a circular saw with a diamond blade is recommended for the job. Abrasive blades may also work, but it is also likely that you will need to replace the blade several times since they can wear out quickly. Diamond blades are much more reliable. 

Meanwhile, if you have a larger project where you plan to cut a trench more than 3-4 metres, a walk-behind wet saw is recommended. Wet saws are also recommended for indoor work as long as there is enough space to use the saw. Wet saws can also reduce the amount of concrete dust that will be created.

Wearing The Proper Safety Gear

Before carrying out the trench cutting job, it is critical that you wear the right safety gear. First, it is important to protect your eyes. Wearing goggles or other eye protection can help keep your eyes from sustaining damage from concrete debris. Sawing concrete is also very loud, so ear protection is another must.

How To Cut Trench Concrete Slab

Aside from eye and ear protection, ensure that you wear a high filtration dust mask to avoid concrete dust from damaging your lungs. Wearing knee pads and shin guards can protect your legs from concrete debris or accidental contact with the saw. 

Heavy-duty boots and gloves are also recommended to wear as a precaution for extreme situations. Steel-capped boots are commonly used in concrete cutting jobs. This will be helpful in case you drop something heavy on your foot or catch an unexpected sharp edge.

Cutting A Trench In A Concrete Slab

The general process for cutting a trench in a concrete slab is relatively similar across projects of different sizes and scopes. The steps presented below highlight the most common method of cutting a trench in a concrete slab. 

Step 1. Choose The Right Equipment

As previously discussed, choosing the right tools is the first step to this concrete cutting job. Make sure that you choose the right cutting tool depending on the scale of your project.

Step 2. Perform Dust Management

Concrete cutting jobs can be extremely dusty, which is harmful for human health. For example, if the job is being done indoors, use plastic sheeting and duct tape to seal off the space before cutting. This is commonly employed as one of the best ways to manage dust. This will also help protect the rest of the area from being covered in dust as well. 

Step 3. Prepare The Concrete Slab

Make sure that the concrete slab is clear of all obstructions. If the concrete has paint or other markings, it is not necessary to remove it unless it obscures you from seeing the cutting lines.

Once you have cleared out the slab, measure and mark the trench that you will be cutting. Chalk is commonly used to accomplish this. Make sure your lines are as thick and bold as possible.

Step 4. Create A Guide Cut

Once you have set your equipment up and put on all your safety gear, you can begin the cutting job. Generally, most saws can adjust the depth of the saw blade, so adjust the saw in such a way that you can achieve a cut half an inch deep.

Cutting a shallow line will make it easier for the saw and for you to control the saw. Do not cut concrete for more than 45 seconds at a time as the blade gets hot very fast.

How To Cut Trench Concrete Slab

Step 5. Finish Your Cuts

After you have made your guide cuts, reset the depth of the blade according to the depth required. Be mindful of the blade overheating. It is recommended to let the blade cool every 30-45 seconds. Go over the guide cuts slowly and ensure that you maintain consistent control over the cut.

Step 6. Remove Concrete From The Trench

Once you have made all of your cuts, make sure to remove concrete in between the cuts. Sledgehammers are commonly used to break up concrete for removal. However, for bigger jobs, you may choose to use a jackhammer.

3 Ways To Control Dust When Cutting Concrete

When it comes to cutting concrete, there can be a lot of hazards that occur in the process. Some of these hazards may involve loud noises or improper equipment handling; however, one hazard that is extremely dangerous is the production of dust.

Dust in concrete cutting can be harmful to human health for a number of reasons. Because of this, there are important precautionary measures one must take in order to protect themselves from dust when cutting concrete.

But how is dust harmful, and what are some ways to control it? If you want to learn more about this, please keep on reading below.

Dust And Concrete Cutting

Cutting concrete produces huge amounts of dust. Crystalline silica is commonly found in concrete; as such, once it is cut, the dust can produce very small particles of silica.

However, when the dust becomes airborne, it can easily lodge itself into our lungs, most especially since dust containing silica is so fine. If you have prolonged exposure to concrete dust, this can lead to irreversible lung damage or illness such as emphysema and chronic silicosis. This can not only affect the quality of life but even lead to death.

Therefore, the importance of controlling dust when cutting concrete is undeniable. Because of this, there are various methods by which dust can be controlled.

3 Ways Control Dust When Cutting Concrete

3 Ways To Control Dust When Cutting Concrete

In general, there are three ways that dust can be controlled when cutting concrete. These methods differ based on the techniques and equipment that are used such as the following:

1). Wet Cutting And Water Suppression

Wet cutting is a dust control method that adds water into the mix in order to reduce the amount of dust that is produced. In fact, it can reduce the dust generated by up to 85% in comparison to cutting dry concrete.

While water is used to control dust, it can also be used to reduce the temperature of the diamond blade used to cut the concrete. This helps keep the blade cool, further expanding its lifespan. A cooler blade in wet cutting can also allow you to make precise cuts especially since you won’t have to wait for it to cool when dry cutting.

Typically, water is directly hosed onto the rotating cutting blade while it is functioning. Continuous water flow is also directly pumped onto the cutting area while the saw is in use.

From here, water mist is sprayed in the air to allow concrete dust to settle more quickly. Water jets are used to suppress dust emission. This takes form as pressurised tanks that contain a minimum of 8 litres of water to produce a ratio of ½ litre of water per minute rate, further controlling dust emissions.

Because you will be dealing with continuous water flow, ensure that you make use of the right equipment that can cope with water containment and the collection of concrete slurry. 

2). Dust Extraction

Dust extraction makes use of systems such as high powered vacuums that have specialist air filters. These are fitted to a tool that can extract dust in the stages of cutting, sawing, or drilling.

Using the proper dust extraction equipment is critical, especially since they are specifically designed to capture all dust. Make sure to give careful attention to the dust collection bags and filters. Empty them, clean them, and change them regularly to avoid clogs or overfilling.

3). Respiratory Protective Equipment

Respirators help give additional protection from airborne particles produced during concrete cutting. They are often used together with another dust control method (whether it be water suppression or extraction). Using the right respirator is important and must adhere to safety requirements.

Summary

Concrete cutting can be a dangerous job. While there are various hazards associated with it, the production of dust is one that can cause irreparable health damage.

As such, employing dust control methods and safety measures is critical when cutting concrete. While water suppression and dust extraction can be classified as dust control methods, using protective equipment such as respirators should also be used in conjunction with these methods.

What Are The Dangers Of Cutting Holes In Concrete Walls?

When it comes to cutting, drilling, or sawing concrete, it can be a very tricky job. There can be some serious hazards if you do not take the proper safety precautions beforehand.

Cutting holes into or sawing concrete walls is no exception to this. It is important that you are aware of what potential hazards might occur if you do not protect yourself before you cut holes into concrete walls.

If you would like to learn more about some of the dangers that come with cutting holes or sawing concrete walls, then let’s explore this in more detail below.

The Dangers Of Cutting Holes In Concrete Walls

Safety should be of utmost priority when it comes to any type of concrete cutting job. There are many hazards that can occur with projects such as these that can pose a real danger to your health, safety, and overall well being.

More importantly, a seemingly simple concrete cutting job such as cutting holes in concrete walls can be deceivingly easy. However, safety should not be neglected from a job such as this. Here are a couple of dangers that you may come across if you do not protect yourself in concrete hole cutting jobs:

1). Flying Debris 

Flying debris is something you will encounter in any concrete cutting, sawing, or drilling job. When cutting holes in concrete walls, you may encounter flying debris such as drywall particles or wood shavings. 

Flying debris is very dangerous because it can penetrate the eye and cause serious damage. The dust from cutting may also cause respiratory problems, which is particularly detrimental for individuals that already have existing issues such as asthma. 

As such, it is important that you wear the appropriate personal protective equipment when carrying out this type of job. 

2). Unmaintained Equipment

Maintaining your equipment is very important. If your equipment is faulty, this will not only compromise the integrity of your project but jeopardise your safety as well. 

For example, you must ensure that the drill or saw is kept dry at all times. This is because if the drill is wet and you accidentally hit an electrical wire, you can experience an intense electrical shock. 

Another example is that drills and saws can burn your skin since they become hot after use. Keep the drill away from pets and children and handle it with caution to avoid injuries. 

3). Electrical Hazards

Electrical dangers are a common occurrence when it comes to cutting holes in concrete walls. When cutting holes, make sure to avoid drilling above, below, or near light switches or electrical outlets. Hitting an electrical wire with a metal drill can lead to electrical shocks.

If you plan to drill a hole into a concrete wall of a two-story house, make sure to take extra precautions in avoiding electrical wiring. This is because it can run above, below, or on either side of a light switch or socket.

Some modern homes may have electrical wiring encased in steel plating. To prevent sustaining an electrical shock, make sure that you should check electrical plans if possible or seek advice from an electrician.

4). Improper Attire

Wearing the right attire is imperative when it comes to cutting holes in concrete walls. Loose clothing or long sleeves can easily get caught in the drill or saw, causing possible injuries to your hands or fingers. Make sure that you are wearing the right attire – that is, anything that is not loose. 

Summary

When cutting holes or sawing into concrete walls, you must make sure to take the necessary safety precautions beforehand. While it may seem like a simple job, there can be potential hazards if you do not protect yourself.

Some of these hazards include sustaining injuries from flying debris, hitting electrical wires, getting clothing caught in the drill, and misusing your equipment. All of these dangers must be considered before you choose to cut or saw holes into your concrete wall.

Types Of Non-Destructive Concrete Testing

There are numerous techniques used to perform non-destructive concrete testing. Here are just a few of them down below:

1). Penetration Tests

There are various means of penetration tests, but the Windsor probe is generally considered the best. It consists of equipment including a powder-actuated gun or driver, loaded cartridges, hardened alloy probes and a depth gauge to measure the penetration of probes.

It functions by driving a probe into the concrete through a precision powder charge. The depth of the penetration indicates the compressive strength of the concrete.

The manufacturer is in charge of providing calibration charts, but the instrument must be calibrated for the type of concrete and the type and size of the aggregate used.

2). Dynamic Non-Destructive Test

Dynamic tests make use of resonant frequency and mechanical sonic and ultrasonic pulse velocity methods. They are able to evaluate the durability and uniformity of the concrete, while also being able to estimate its elastic and strength properties.

The only technique under this test is known as the ultrasonic pulse velocity method. It measures the time it takes for an ultrasonic pulse to pass through the concrete.

Pulses are generated by shock-exciting piezoelectric crystals where similar crystals are also contained in the receiver. The time it takes for the pulse to pass the concrete is measured by electronic measuring circuits. 

3). Pull-Out Tests

A pull-out test uses a special ram that is used to measure the force that is required to pull a specially shaped steel rod from the concrete. In this process, the concrete is also in tension and in shear. The force that is required to pull out the concrete is also related to its compressive strength.

The pull-out technique can therefore quantitatively measure the in-situ strength of concrete if proper correlations are made. Over a wide range of strengths, pull-out strengths have a coefficient of variation that is comparable to compressive strength. 

4). Rebound Hammer Method

The rebound hammer test is primarily used to estimate the strength of concrete for comparative investigation. It does this by measuring the elastic rebound of concrete.

In essence, it is a surface hardness tester that establishes an empirical correlation between strength and rebound number. The only instrument that can carry out the rebound principle is the Schmidt hammer. It has a spring-controlled hammer mass that, within a tubular housing, slides on a plunger.

The hammer is forced against the concrete surface by the spring. The surface may be horizontal, vertical, or angular, but the instrument must be appropriately calibrated in the position. The distance of the rebound that was created is then measured on a scale. 

Usually, several readings are taken, and they must be both well-distributed and reproducible.

5). Radioactive Methods

Radioactive methods of concrete testing can help detect the location of reinforcement, measure concrete density, and determine if honeycombing has occurred in concrete units. 

The equipment used for this method is relatively simple and affordable, but the initial price can be high. Concrete that is up to 18 inches thick can be easily examined with radioactive methods.

Summary

Non-destructive concrete testing actually involves many scientific principles and intricacies. It is not an easy job to do, which is why many skilled and specialized experts help handle jobs such as these.

However, there will be situations when you have no choice but to cut or dig up the concrete depending on what tests are being performed and why. If that is the case, then MEGASAW is here to help.

Common Mistakes When Cutting Or Drilling Concrete

When it comes to drilling or cutting concrete, you may come across a couple of mistakes. These mistakes often come at the expense of your own and others’ safety.

Because of this, it is important that you always come thoroughly prepared before cutting or drilling concrete. Being aware of common mistakes that can occur in projects such as this is an important step towards preparedness and prevention.

If you want to learn more about some common mistakes that occur when cutting or drilling concrete, then please keep reading as we explore this in more detail below.

1). Assuming All Concrete Is The Same

Assuming that all concrete is the same is one of the most common mistakes when it comes to concrete cutting or drilling. It is important to remember that concrete is a mixture of various additives that can affect its strength, density, and other characteristics.

Because there are different mixtures used for, say, a concrete foundation than what there is for concrete driveways, it is important that you do not treat these concrete types the same way. 

This means that you will need to pick appropriate equipment and apply appropriate pressure when cutting concrete. For example, thick concrete may need a rotary hammer to break it up, while a masonry drill can be more suitable for softer concrete

As mentioned, adjusting the pressure of the concrete cut is also important. This is because if you do not adjust the pressure you apply when cutting concrete, this can lead to defects such as cracks.

2). Not Knowing What Lies Beneath The Concrete

This particular mistake can be particularly detrimental for your safety and your coworkers’ safety. For example, if you cut through a concrete wall in a hoe, there could be materials such as plumbing pipes or electrical wires underneath.

Accidentally cutting materials such as pipes or wires can lead to some serious injuries or structural damage to the property. Therefore, it is important to check the property’s blueprints so that you can avoid unnecessary damage.

It is also important to discover if there is rebar beneath the concrete. Rebar is commonly used to strengthen the concrete. As such, you will need different tools like a diamond drill or saw to cut through rebar. 

3). Not Changing Equipment When Handling Different Materials

Using the right equipment is vital when you are handling different materials. For example, masonry bits and blades should only be used to cut concrete, not tiles or asphalt. 

Therefore, if the concrete cutting job has an element of cutting other materials simultaneously, then do not assume that your equipment can cut through concrete and the other material as well. 

Make sure that you change your blades and bits to prevent damage from harder materials and avoid cracked or broken tiles, woods, tempered glass, etc.

4). Not Using Water Properly

Water is actually an important part of concrete cutting jobs because a lot of dust is often created. However, when using water, make sure you do not pour a long stream over your cutting or drilling area. This is because it can create a mess, which can be disruptive for the cutting process.

Rather, pour just enough water so that the dust can be gently rinsed away. Make sure to keep the work area clear. Stop cutting or drilling concrete if you do not see a chalk line or drill bit as you work and wash the area away. Make sure to adjust the water you use accordingly as you work.

Final Thoughts

Concrete cutting can be considered a risky job. There are a lot of potential hazards that can occur if you do not take the proper precautions and preventive measures beforehand.

Therefore, it is important to be aware of what can go wrong if you do not prepare yourself for any type of concrete cutting job. With this quick guide, we hope to have helped in advising you on what you should avoid when cutting concrete.
