Hello,
I'm doing a bathroom renovation and found some fist-sized divots in the concrete slab once the old vinyl floor was removed and the trim off. Two of those divots are near pipes - one's a copper hot water heater pipe for a baseboard heater, and one is a larger (presumably) sewer pipe.
The sewer pipe is "in the wall" and I'm tempted to leave it alone and not try to fill it. The copper pipe has some paper around it (insulation?). The paper is down to the concrete, but I'm thinking that I need to use some insulation if I want to patch the hole? What's best to put around the copper pipe here? Obviously, I can't remove the existing heater or pipe to add plastic. Is foam insulation sufficient, then fill the hole with patching cement?
The hole is essentially in the corner of the room, so I can't lay tile until I solve this. The house was built in the late 60s.
Thanks!
