I have a house with a very large hole around the sewer pipe. Pipe is copper, if that matters. the hole is from 2" to 6" around pipe, crudely cut out.
I need to fill this, since I've been getting water through it. I seems too large for hydrolic cement.
I was thinking of wrapping the pipe with rope and some plastic, then filling the hole with regular cement. Once the cement cures, pull out the rope and plastic. this should give me some space between the cement and pipe to seal with a good waterproof caulk (velkum 116, or other) or some hydrolic cement.
I plan on using a bonding agent to help the old and new cement attach better.
Any thought on my plan???
thanks.
