Installing conduit under or in concrete slabs protects the wires from the weight and corrosion of the cement.
Cutting concrete slab for electrical conduit.
The concrete will ruin your saw blade.
Instead finish the cut with a utility knife.
Save the piece for later.
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.
Set the diamond blade on the concrete wet saw to a depth of 4 1 2 inches and cut along both chalk lines.
Next cut out the exposed strip of plywood or osb that covers the slab but don t go all the way through.
Step 7 backfill around the pipes.
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.
