Cutting Concrete Slab For Electrical Conduit
In this video we are cutting concrete with a circular saw aka skil saw.
Cutting concrete slab for electrical conduit. Set the diamond blade on the concrete wet saw to a depth of 4 1 2 inches and cut along both chalk lines. Step 7 backfill around the pipes. Installing conduit under or in concrete slabs protects the wires from the weight and corrosion of the cement. Use a chisel and hammer to remove the three scrap pieces.
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. It also allows future expansion of the electrical system by pulling additional wires through the conduit. Instead finish the cut with a utility knife. The concrete will ruin your saw blade.
Make a second cut inch away and parallel to the first. Save the piece for later.
