Concrete cutting purpose

It’s an unfortunate fact that concrete and asphalt can crack when they dry. This can be caused by the excessive water content of the concrete mix, drying too fast, thermal expansion and contraction, among other causes. 

For homeowners, cracks in concrete can be an eyesore. What’s more, it can also deteriorate the concrete which can become very costly and inconvenient to rectify. 

If you do have cracks on your driveway, or worse, your walls, you will have to use fillers and paint to fix the problem. 

For a commercial building, cracks on your walls, floors, and driveways can be a safety concern. Fixing them can cost you hundreds if not thousands of dollars. Therefore, prevention is better than cure. 

Concrete Sawing

Concrete sawing helps control cracking and will save you from expensive repairs and maintenance however, timing is very important in cutting. If you saw-cut too soon, you will spoil the integrity of the concrete. If you cut too late, it will defeat the purpose of cutting. 

For concrete, depending on the local weather conditions, cutting can be done within four to 12 hours after the concrete is poured. In hot weather, cutting can be done within one to four hours after the concrete is poured. 

Cuts should be about one third the depth of the concrete. Once you start cutting, you must make sure that you continue the process and finish as soon as possible before the concrete temperature falls. 

It should be done when the concrete has set enough to tolerate the sawing but not set too long that it cracks even before cutting. 

Asphalt Sawing

Cutting asphalt is necessary for fixing cracks, asphalt replacement, repairs, and maintenance. Asphalt deteriorates because of soil movement, wear and tear, and many others. 

Unlike concrete, asphalt requires a specific saw blade for cutting. Asphalt is softer compared to concrete, so soft-bonded blades will not cut it. A diamond blade with a hard bond is more effective. 

Two types of blades are used for cutting asphalt – wet and dry blades.
