Why is water leaking around a pipe in my basement wall?

Water can leak around pipe penetrations when small gaps form between the pipe sleeve and the concrete foundation wall. During heavy rain or snowmelt, groundwater pressure can force water through these openings and into the basement.

How do you repair a leaking pipe penetration in a foundation wall?

Leaking pipe penetrations are commonly repaired using high-pressure polyurethane injection. Expanding resin is injected around the penetration to fill voids behind the wall and create a watertight seal that prevents groundwater intrusion.

Can a pipe penetration leak be repaired from inside the basement?

Yes. Most pipe penetration leaks can be repaired from inside the basement using injection methods. This allows the repair to seal the leak without the need for exterior excavation.
