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.

Precautions

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.
