Most Common Concrete Cutting and Drilling Hazards and Their Solutions

The highly crucial projects involving concrete cutting and drilling come with different risks and hazards. Experienced people dealing with such projects understand those risks very well and are able to resolve them successfully.

Outlined below are some of the most common concrete cutting and drilling hazards along with their solutions:

a) Kick Back

This signifies violent or sudden movement of saws away from cutting surfaces, posing extreme risks for both bystanders and the operators. Different types of injuries may occur, including, bruises, fractures, cuts, and strains. Any contact with blade signifies lethal lacerations. There can be numerous causes for kickback, including the presence of unstable surfaces, embedded objects as pipes or wires, and cutting above the shoulder level.

Some of the precautions to minimise the chances of kickback include appropriate equipment selection and use of scaffold for projects over shoulder height. Careful consultation with the builders plan helps in avoiding embedded objects. Also, keep bystanders at a safe distance, away from an ongoing project and never circumvent or remove guards.

b) Inverted Cutting

It is important to take certain precautions related to inverted cutting to ensure smooth operations and keep hazards at bay. It involves cutting slab undersides, overhang, or floor. One should never undertake to do this using a hand-held saw since this affords little control on cutting machines present over shoulder height. Only, appropriately trained operators should undertake such projects that too using wall track-mounted saws. Never use water-cooled saws for such projects because water will flood inside the motor and create yet another hazard.

c) Noise Generation

Excessive generation of noise at the cutting site is another possible hazard. It may lead to damage of hearing because of extremely loud noise in short periods. Lower noise levels for lengthened periods may also create problems. It is important to implement control measures to keep the chances of damage to the hearing to a minimal.

For minimising or eliminating noise risks use saw noise-reduced blades, quietest blades and equipment, and gain information regarding equipment noise levels prior to purchase. Those who are not related directly to concrete drilling and cutting project should stay at least 7 m away from the job site. Use of hearing protectors is another precaution that can minimise the risks related to generated noise.

d) Gases & Dust

In order to deal effectively with gases and dust generation related to concrete cutting it is important to take the right precautions. While use of equipment for dust extraction and water suppression is ideal, it is not possible to apply them in all scenarios. If possible, use slower masonry and concrete drilling or cutting equipment, which generate minimal dust, if any. It is important to use respiratory guards at such project sites to keep health hazards at bay. Filter particulate respirators are a good choice since it gives protection against,

  • Dust
  • Fibres
  • Lead Fumes
  • Asbestos
  • Silica

Silica dust is a major cause behind silicosis, chronic problem that leads to scarring and stiffening of the lungs. While symptoms are quite slow to appear it ultimately leads to health degeneration of the patient. Carbon monoxide gas emanating from concrete cutting sides is extremely hazardous. This odourless and colourless chemical asphyxiates, causes unconsciousness, rapid coordination loss, and even death. Respirators covered by OSH regulations are ideal for use in such environments.

e) Manual Tasks

Manual tasks related to concrete cutting projects bring with them a variety of hazards such as static or awkward working positions maintained/repeated for long periods of time. Trip and slip hazards or violent reactions of a different equipment are other problems that may crop up anytime. Use of proper support frames can minimise repetitions and holding of static positions. Whenever possible, try using lighter equipment, reduction in movement range, proper safety training for operators, and pre-check blades and different components.

f) Electricity

One cannot emphasise enough the hazards posed by electricity during concrete cutting. Pooled water always increases the chances of electrocution; therefore, its removal with dry or wet vacuum cleaner is necessary. In order to go for wet cutting always use petrol engine, hydraulic, pneumatic powered equipment and try avoid using those powered by electricity. Any electrical portable equipment in use should have protection against Earth leakage. Regular inspection and tagging of equipment with trained technicians is crucial too.

g) Vacuum Pressure Loss

Those who use vacuum assembly for anchoring stands of core drills are open to injuries if slurry, fills in the vacuum pump, leading to vacuum loss so that drill stand breaks free. In order to avoid this the operator should utilise bolt stands at least whenever possible. Use of sound surfaces for use of vacuum attachment is necessary, and so is monitoring of equipment on a regular basis to ensure vacuum pressure maintenance.

How to Control Noise and Dust When Cutting Concrete

Anyone who’s ever tried cutting concrete will tell you that dust and noise are two of the biggest deterrents to the job.

Concrete dust containing silica and a variety of other hazardous materials can lead to severe breathing issues, and the high noise levels can damage hearing.

Fortunately, there are effective ways to control noise and dust associated with concrete cutting.

So what methods work best for controlling noise and dust? Dry cutting as everyone knows gives rise to large amounts of dust laden with silica, which is the single most health-damaging component of concrete dust. These abrasive tiny particles,

  • Damage the lungs of a person
  • Reduce the capacity to breath
  • Leads to chronic breathing trouble

Continuous exposure to silica may lead to lung cancer, tuberculosis, and COPD.

Dust and noise associated with concrete cutting at construction sites are a serious health hazard leading to respiratory illness and hearing loss to the workers.

One of the crucial engineering controls for minimizing the damage and developing a healthy environment for workers is the application of the wet method of cutting concrete. Studies indicate that the use of water in relation to concrete cutting can reduce the concentration of hazardous dust to a staggering 85%.

“The wetter the better” seems to be the motto when it comes to concrete cutting. This is an evidence-based finding, so it is completely dependable.

According to a recent research, respirable geometric mean concentration of dust through dry cutting is approximately 14.396 mg/cubic meter, which is 10 times more than wet cutting projects.
The use of water hose during concrete cutting reduces the amount of silica dust to just under 1.1 mg/cubic meter. Spray control on the other hand, allows only 1.2 mg/cubic meter of silica dust to escape to air.

Studies undertaken in relation to various tools for concrete cutting have thrown up startling results, but all seem to indicate towards one thing.

Based on OSHA regulations, one should never use concrete gas powered saws for dry cutting.
The only exception can be made in cases where the construction firm is ready to take the onus for a sampling to ensure that dust exposure never increases above the allowed limits.

However, by knowing the exposure levels related to various concrete cutting projects as well as in relation to two different types of equipment used, it is possible to take the necessary precautions.
Through the use of the right respirators, it is possible to keep dust and noise exposure levels to a minimum. Regularly using water controls with concrete gas powered saws is an effective and proven way to reduce respirable dust levels significantly.

Aside from ensuring the safety of the workers, firms also need to ensure the well-being of the onlookers and other people present on-site.

In addition to using the right methods for concrete cutting, preferably the wet one, it is important to use the right precautions to ensure complete protection from dust and high decibels.

Here are some protective measures approved by OSHA for ensuring the best results related to concrete cutting projects without compromising the workers health:

A. Use of respirators: Respirators offer the best protection against dust laden with hazardous silica. Proper training related to this protective equipment is necessary to ensure optimal benefits. It is the job of the project manager to ensure effective training.

B. Use of safety glasses: Use of proper safety glasses is extremely necessary to keep the eyes protected throughout the cutting process.

C. Good quality headgear: When you are protecting all the parts of your body during concrete cutting, it is important to consider a good quality headgear too. A hard hat forms a barrier against falling objects, so its importance should never be underestimated.

D. Proper hearing protection: Proper hearing protection, such as earmuffs and earplugs are another must have when it comes to concrete cutting sites. However, it is important to replace them on a regular basis to avoid chances of getting ear infection. Also, proper training in this regard is necessary.

E. Use of proper foot protection: The wearing of proper footgear is extremely necessary for protection against twisted ankles or abrasions of any kind. Over-the-ankle leather solid boots are a good choice.

Studies indicate that the use of wet cutting methods for concrete is the best way to keep workers safe from the hazardous dust.

However, for ensuring better control of noise, it is important to use high-quality equipment and maintain them in good order. This, along with the use of the right protection is a surefire way to maintain optimal construction place conditions.

How to Remove a Concrete Slab for Underground Plumbing or Electrical Work

People who have concrete floor and driveways at their homes or concrete sidewalk around it, may actually need to break up the concrete for underground plumbing, utilities repairing, or maintenance. This can be a daunting job, but here are a few basic steps that will prove to be helpful in this regard.

1.The first step is to determine the exact position where the concrete needs to be broken. Locating the exact area of the problem can save a considerable amount of time and money, and complete the job with greater efficiency.

  • If you are looking for plumbing related problems, locating the area and the depth of the pipes running underground is important. Exterior hose valves or clean outs are pretty helpful for identifying the location and the depth of those pipes
  • For water problems, try to locate areas where water is bubbling up through a crack in the surface of the concrete, or is seeping out from the edges
  • For electrical faults, before you start digging the concrete, you need to locate the conduit outside it, and then dig up a certain length for finding where the rest of it is running to
  • For installation of new utilities or other repairs that require excavating an area of the concrete cover, it is wiser to consult the construction plan and then come out with a design and place to start digging

2. Once you know where you will be digging the concrete, now it is time to determine the thickness of the slab. You can dig the ground at the edge of the concrete cover and take a look at the side of the slab for a more or less precise idea. But some concrete flooring has thicker edges, while others may come with abutting structures and a monolithic foundation that prevent digging. So, it is a good idea to hammer a drill at the place one needs to dig and have an exact idea of the actual thickness or the constructional structure of the slab. Electric clipping hammers are suitable for breaking up concrete slabs around 4 inches thick, but for thicker slabs around or more than 60lb; electric breakers or pneumatic jackhammers would be a better choice.

3.Once the research and homework is done, it’s time to gather the tools for the project. If the concrete is less than 4 inches thick or it is a small project, a sledge hammer is sufficient. But in many cases, power equipment like a demolition saw, a circular saw with dry cut masonry blades, and a chipping hammer may be needed.

4. Mark the digging area clearly, so that you can dig it in a regular shape, and make the finished job look neat and also less evident. Once the area is marked, then saw cut the line as deep as possible. A demolition saw, a circular saw, or even a grinder with a dry cut diamond blade can be used for the purpose.

5.For heavy hammer drilling, you need a rotary hammer or a breaking chisel to chip the concrete. First, break along the edges of the saw line, with the point of the chisel leaning towards the line. This will loosen the edge crack, but will not break the sides. Care should be taken not to chip or spall the adjoining concrete. You need to work around the area to enlarge it, while digging deeper, until the slab is fully penetrated.Until you create a space for the broken concrete pieces to drop in, they won’t be able to come free.

6. While digging a concrete slab, the point of the chisel should always be slanted towards the initial hole, so that it penetratesin the right direction, without breaking any concrete. If one penetrates straight too deep then that piece will be lodged in as a whole, and will not also be easy to remove. By chipping in parallel to the original hole, concrete bits that have lodged can be removed.

7.Try to break out the largest piece while digging, so that the hole becomes large enough. While working on the edge, chipping small pieces is nothing but a waste of time and energy. As the hole grows bigger, simultaneously remove the broken pieces, so that, there is enough space for the subsequent pieces to drop in without getting wedged. This will also help you to dig the spot pipes, reinforcing bars, or electrical wires,as the penetration continues.

8. Once the breaking is complete, use a chipping hammer for chipping the edges. This will fully thicken the repair, and will further prevent cracks from appearing once the patching is done.

9. Once the pipe is located,the digging needs to be done, along the length of the pipe to reach the actual damaged section. It is important not to further damage the pipe, while breaking and digging the concrete. Once the actual location of the damage is identified, breaking vertical concrete chips might be easier, but the adjacent surface must be protected, too.

10. Once the fault is rectified, the debris should be removed,before the hole is patched with graded and compacted fill material and new concrete. One can also use a sand layer to prevent the pipes from being damaged by the movement of the hardening concrete.

Here are a few more tips that you might find useful.

While working close to the pipes or other fragile equipment, it’s a good idea to use smaller tools. If you need to work on an area that is larger than 15-20 square feet, renting a jack hammer or a qualified demolition professional would be wiser.

Large hammer drills or rotary hammers, which are the best equipment for such jobs, are quite expensive. If they are required only for a single project, then renting them can be a better option than buying.

When digging a concrete slab also see to it that the reinforcement bars are not damaged, so that the patch and the original slab will be of the same strength.

Factors to Keep in Mind Before Buying A Wall Mounted Saw

Wall mounted saws are very effective when there is a need to cut concrete at high heights and flat surfaces. Hence, for creating a clean and precise cut, selection of a wall mounted saw packed with modern technical features and featuring a portable design is necessary.  A highly efficient and versatile wall saw, is certainly a worthwhile investment. However, buying a wall mounted saw involves weighing several important factors as discussed below:

Easy Portability and User-friendly Design

An important consideration when buying a wall mounted saw is its design and versatility. It should be lightweight and designed to be portable, and it should also be easy to store when not in use. Read the mounting features very closely and find out the limitations and benefits it offers when it comes to performing concrete cutting on a bench top surface. Mounting features should provide complete flexibility to mount it at various heights. New modular models are easier to install and use, because they have user friendly controls as compared to several models that are bulky and complex to operate.

Power and Efficiency

For optimum performance of the wall mounted saw during cutting, a continuous water supply plays an important role. For this, it is necessary to buy a wall saw with a water cooled electric motor. Wall saws with this feature are very low weight and deliver remarkable power to the spindle. For seamless performance and control, make sure you purchase one which comes with a high performance two-speed water-cooled gearbox

Blade Type

Another important factor to consider is the versatility of the saw. It is easier to make a wide variety of cuts in length with a wall mounted saw that comes with a T-shank jigsaw blade and replacing the blade should be quick and easy.

Type of Motor

When making cuts on materials with different hardness, a variable speed motor provides better productivity since switching to a different speed for each type of material is easy.  These

machines can be used to create a precise cut for door openings, ventilation channels, window openings, dovetail cutting, special cutting, flush cutting and various diverse applications of concrete cutting.

Blade Guard

There are different makes and models of saws available on the market that come with various blade guard settings. Replacing the blade should be relatively easy for contractors. Don’t forget to read the technical specification on the type of blade, which needs to be used with the wall saw. Blades with various diameters should easily fit with the saw to complete cutting in complex places and precise cutting of various material types.

Remote Controller & Display

Don’t forget to check the features of the remote control which gives you complete flexibility in operating the wall saw at a safe distance. Have a look at the technical features and check for the longest distance from where you can operate the saw and examine the size of the LED display. The technical specs are important  in ensuring the you will purchase a machine that will give you complete control over the sawing process as it provides detailed information about the power level, operating time, current, pressure and service period.

Ease of Maintenance

Finally, an important factor to consider is the ease of maintenance of the saw. Unless the saw is long-lasting and resilient, it will not be a good value for money.  For further convenience, it often comes with a dust port that can be attached to the shop vacuum for keeping the space clean and improving visibility. Thus, it should be extremely convenient and simple to maintain and clean a well-chosen wall mounted saw.

Cutting Concrete Inside The Building Or Construction Site?

No one can deny the importance of cutting concrete for construction purposes. Nevertheless, it is necessary to take care of safety measures and precautions.

Construction workers have to make do with limited spaces and cloistered areas when dealing with concrete cutting. This renders the job quite difficult and not to say hazardous. It is necessary to demand ample space and proper ventilation for getting on with such endeavors successfully and without untoward happenings. Here below are some safety measures and precautions to take during concrete cutting.

Consider Ventilation

Experts and experienced campaigners believe that ventilation is the most crucial factor it can be the difference between a safe work environment and a hazardous one. If you are working in a confined space, ensure that there is proper aeration available.

Choosing the Right Equipment

In order to ensure that chances of accidents are kept to the minimum use of identifiable, active minds for cutting concrete is necessary. With the high developments in technology, nowadays such instruments are available that can work successfully and uneventfully even in cloistered spaces. Whether there is restricted ventilation or completely closed environment, you can use them with aplomb and get positive results in a hassle free manner. Not only is productivity high but also you can stay away from unnecessary trouble onsite. Equipments using electrical cutting technology use vacuum or water for dust suppression and this make them ideal for closed space or indoor use.

Use of Wet Cutting Technology

Those who are looking for a cost-effective technology coupled with a secure work process do not have to look beyond wet concrete cutting technology. However, this may not be thoroughly suited for indoor use. Professionals need to consider water damage, prevention measures and most utilize vacuum systems or protective sheeting to ensure such protection.

Using the Vacuum System

Another interesting method of successfully dealing with the waste from wet concrete cutting which is in keeping with the latest technological innovations is use of vacuum systems. This system attaches directly with a concrete hydraulic chain saw. This is ideal for collecting the slurry created from wet concrete cutting. This slurry remains collected in a secure tank, which you can roll around easily on a job site. Today, it is also possible to find a vacuum system containing attached floor squeeze mounted on the tank for ease of use.

Health Considerations

Besides taking care of the job site, condition protection it is necessary to remain aware of the health issues related to concrete cutting. Continuous exposure to concrete dust during cutting can lead to a wide variety of health hazards. For example, contact of wet concrete with skin may lead to appearance of rashes, skin irritations, and burns.

Contact with eyes leads to similar results and it may even need medical intervention. Prolonged exposure to concrete dust while cutting enters the lungs and because of the presence of crystalline silica may lead to such serious conditions as silicosis. This disease has long-term repercussions taking away the ability of an individual to work and lead an active life. High degree may even lead to life-threatening conditions. For the prevention of such occurrences, it is preferable, if you wear gloves during the process along with goggles for giving your eyes adequate protection.

A Quick Guide For Safe And Secure Concrete Cutting

Usually every construction project is engaged in some type of cutting concrete or core boring. Cutting concrete may appear to be simple and easy, but in real practice there are many aspects that need to be considered for a safe and successful concrete cutting.

Safety Measures to Consider

To start with you must understand that concrete dust is potentially harmful to the lung sinuses and eyes. It may also damage nearby finish.

Dust control should be an important aspect that should be given due consideration. The two ideal dust control systems are wet cutting in which the dust is accumulated in the cooling water and another one is pneumatic devices that sucks the dust in an air stream.

When leveraging a diamond cutting blade or any other abrasive disk cutting apparatus, the water work as lubricant and simmers down the temperature of cutting device. You should handle the spillage of water onto the area that is being cut. Specific drainage should be provided or a vacuum system to control the cooling water from spreading.

Proper grounding and insulation is also vital in using electrically driven tools. Some extra precaution should be observed when using core drilling appliances. Several machines work on the suction theory to retain the base in place while the drilling process is on.

How to Cut Concrete

Any surface deeper than 4 inches can be easily cut with hand saw, but with the increase in depth of the surface being cut, the difficulty increases. Cutting concrete thicker than 6 inches warrants a professional expertise and intervention to perform the task professionally and safely.

Lay out the surface to be cut. Draw a chalk line to delineate the exact area of cutting on the concrete. Now take a 15-amp circular saw having a diamond or abrasive blade for cutting the thickness of 2 inches. This saw will work best when working with a sidewalk machine. Set the blade of your circular saw at 2 inches.

Start sawing at the brim of the concrete and gradually saw on the line you have made with your chalk. Keeping the blade wet by dripping water on it can reduce dust and keep the blade smooth and cool.

The thickness of the cut will provide you with a straight brim allowing the concrete to complete breaking the other remaining thickness and a straight edge on the top to combine with a new and fresh concrete.

How to Cut Concrete more than 4 inches Deep

You should put to work a gasoline or electric powered cutoff saw to perform the task when you have to cut concrete that is deeper than 4 inches. The cut-off saw enables you to sink deep up to 6 inches. Most housing platforms, driveways, and basement or concrete walls are found in this range.

You should follow the same guidelines of drawing a straight mark to follow on the concrete slab to ascertain your starting point. Now cut the concrete to the right depth. Progress gradually, maintaining the line of the cut-off saw. Easy going speed enables the saw will not allow the blade to overheat and will not allow the shrapnel type pieces to be flung out into the air from a broken blade causing damage to your health and damaging the well being of nearby areas.

You can also keep an assistant to remove the dust from the chalk line to view the saw cut and keep the dust under control.

Concrete cutting is one of the most vital activities that are found in almost all kinds of construction projects. If you are in the sector of the construction industry and used to perform concrete cutting, you need to keep yourself updated with prominent tips and warnings that you should follow to successfully perform your duties and keep yourself abreast with the latest development and technologies!

Concrete Cutting Techniques, Learn from the Experts

If you are professional dealing in construction sector you would be aware that every construction project requires some type of concrete cutting or core boring. It may be appearing quite simple and straightforward, but practically there are many factors that require attention to execute a safe and successful concrete cutting project.

Concrete cutting calls for sharp and appropriate tools; best equipments in good shape; good supply of cooling water and of course an apt and experienced operator. Concrete operating cutting equipment can be used simply and safely but for this you should be well acquainted with the potential hazards and must be aware of the functions and features of the device you are operating.

You can employ different mechanisms and tools when it comes to cutting concrete. A basic knowledge of concrete-cutting processes can be of the essence for you to perform a project.

Diamond Drilling

Diamond saws work fast and precisely compare to other cutting techniques. You would also need fewer operators and it can also enable you to cut reo bar and other metals that are often required in the construction process. Diamond saws are noiseless and generate least vibration compare to any other type of drilling and cutting tools. At the same time they’re less likely to harm the surrounding parts of the floor or concrete.

Concrete Wall Sawing

This method encompasses a circular blade fixed on a track-mounted tool. This track enables the tools to climb the walls and cut ceilings also. Generally, this technique is facilitated to cut walls that are thicker than 16 inches and seldom those concretes that are 36 inches thick or more. This is entirely a different technique and warrants experience and expertise.

Wire Sawing

It is used when all cutting methods collapse or go to toss. These are mostly used for larger concrete-cutting projects. These saws constitute of multi-strand cable having small diamond segments aligned through an array of pulleys attached to a hydraulic powered wheel. When the wheels pull the cable the wire spins around and cuts the material.

Flat Drilling

Such drilling process is often used for parting flat surfaces, like floors, pavements and bridge platforms. It’s often considered to be slab sawing also. In this method the tools used are kept on a cart that you can push from the rear. Such process can help you reach broken pipes or wiring under a concrete floor, highway, patching or road and cutting plumbing canals.

Core Drilling

This process of drilling is used for making precise circular holes. You can use this for forming exit for pipes, electrical wires or ventilating, heating, or air conditioning vents to fit through. You can also use this drilling machine for collecting concrete samples. These are steel tubes having diamond-tipped bits.


All the above stated tools are highly effective but at the same time there are certain guidelines that should be followed while using these tools. Concrete dust is harmful to the lung, eyes and sinuses. It also becomes abrasive and corrosive damaging the surrounding concretes too.

You need to control the dust erupting out of this drill bits. It can either be controlled by wet cutting in which the dust is accumulated in the cooling water or using pneumatic tools that can suck the dust in an air stream.

When putting in use the diamond cutting blade or any other abrasive disk drilling device like concrete saw, water is used to cool the cutting tools. You must manage the spillage of cooling water and drainage should be offered or a vacuum mechanism like wet vacuum can be attached to monitor spreading of the cooling water.

It also requires proper grounding, insulation and right ground fault protection. You must also be aware of the possibility of machine base rotates violently without warning. You should keep your body away from the possible rotation route of the device base during a core drilling process.
Don’t forget to de-active any power channels that are in the surrounding of the cutting or drilling operation.

These are the mechanisms and techniques that can be facilitated to cut the concrete using various concrete cutting saws and tools. All these tools are meant for different applications given the situation and requirement of the occasion. As every machine manifests certain flaws if not handled properly, it is suggested to get yourself accustomed with the type of tool you are going to use beforehand to get the best output.
