I recently had to jack hammer out a small section of my basement floor (about 1 1/2 feet tall by about 5 feet wide) in order to install new sewage lines for a bathroom.
When I go to replace the concrete floor, should I add rebar in order to help hold the old concrete to the new concrete or should I just use a bonding agent? The concrete is about 4 inches thick and has a sand base followed by clay. Any ideas?
