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.
Cutting concrete slab for electrical conduit.
The blade that i am using is a bosch db741c 7 inch premium segmented diamond blade.
It also allows future expansion of the electrical system by pulling additional wires through the conduit.
Installing conduit under or in concrete slabs protects the wires from the weight and corrosion of the cement.
Save the piece for later.
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.
Step 7 backfill around the pipes.
The concrete will ruin your saw blade.
Instead finish the cut with a utility knife.
Next cut out the exposed strip of plywood or osb that covers the slab but don t go all the way through.
