Step 7 backfill around the pipes.
Cutting concrete slab for electrical conduit.
In this video we are cutting concrete with a circular saw aka skil saw.
Installing conduit under or in concrete slabs protects the wires from the weight and corrosion of the cement.
The blade that i am using is a bosch db741c 7 inch premium segmented diamond blade.
Next cut out the exposed strip of plywood or osb that covers the slab but don t go all the way through.
Save the piece for later.
Ridged nonmetallic pvc conduit is the right material for this job because it is watertight inexpensive and easy to work with.
Instead finish the cut with a utility knife.
Use a chisel and hammer to remove the three scrap pieces.
It also allows future expansion of the electrical system by pulling additional wires through the conduit.
Make a second cut inch away and parallel to the first.
