I recently had a lead water supply pipe replaced in my 1930's Semi with a MDPE pipe. While running an electrical cable I've had the floor back up and noticed that the sub-floor around the pipe entry is damp. The subfloor doesn't appear to be damp elsewhere - Just around the new pipe: -
I think the hole made in the subfloor/foundation has just been back filled with soil. Not sure how much or a problem this is as the sub-floor is well ventilated and there is an air brick not too far from the pipe entry point.
I'm currently planning on excavating the pipe back out, wrapping it in a bit of DPM and then cementing up the hole in the subfloor. Is this a bad idea?
