How to Cut Concrete Slab Easily and Neatly

You might need to know how to cut concrete slab for any number of reasons. Cutting concrete is necessary for sidewalks, driveways, basement walls, house slabs, and patios. When cutting concrete, remember to wear the proper protective gear to prevent injury.

The first thing you need to do is mark the section you want cut with chalk using a box and chalk line. Create a chalk outline of the area that you need to cut.

Then use a saw to cut through about 2 inches. A 15-amp circular saw would work the best. Use an abrasive or diamond blade to cut. Set the blade depth on the saw to 2 inches and begin cutting. Follow the line of chalk slowly with the saw. You should not go deeper than 2 inches at first because this is necessary for a straight line. Any deeper than 2 inches at first will risk a sloppier, shakier line. It will also give the concrete a clean edge at the top to better combine with fresh concrete.

After cutting the first 2 inches, you may proceed to cut to the correct depth by following the same steps as before. Make sure to go slowly to keep the saw from overheating. Pouring water on the blade can prevent overheating and also keep down dust levels created by cutting the concrete.

For anything less than 4 inches, the circular saw will be adequate to completely cut the concrete. For anything more, however, you should use an electric or gasoline powered cut-off saw.
