Hello, This weekend I am going to pour some cement into a small "well" in my in-laws house where currently water leaks into the house pretty severly at times. It is where the service entrance for the water main is. Where the water main enters the house, it was never sealed properly. My question is - cement can cause copper pipe to corrode, so what would be a good product to wrap the pipe in before pouring the cement? At work, we have a product called "Tapecoat", which is used for pipeline corrosion protection below grade. Would this work on a copper potable water line? Thanks.
