Cutting Concrete Slab For Electrical Conduit

Step 7 backfill around the pipes.

Cutting concrete slab for electrical conduit.

It also allows future expansion of the electrical system by pulling additional wires through the conduit. Set the diamond blade on the concrete wet saw to a depth of 4 1 2 inches and cut along both chalk lines. Save the piece for later. Installing conduit under or in concrete slabs protects the wires from the weight and corrosion of the cement.

Instead finish the cut with a utility knife. If you have installed any electrical conduit which does not require a pressure test tape the opening to the conduit closed with duct tape to prevent concrete from falling in. In this video we are cutting concrete with a circular saw aka skil saw. Make a second cut inch away and parallel to the first.

Use a chisel and hammer to remove the three scrap pieces. The concrete will ruin your saw blade.
