Problem: This century-old home had the challenge of mixed foundation types as well as varying levels. The basement leaked even during moderate rainfall which caused excess humidity and all the problems associated with an excessively humid environment.

Solution: With our interior waterproofing process, we were able to successfully and permanently fix this leaky basement. We waterproofed the leaking walls, improved the drainage in the space and also installed a sump pump more than capable of helping to keep the basement dry.

We installed a new liner, lid and pump at this sump location in a St. Thomas home. There was also floor-wall joint seepage present, so we installed our WaterGuard drainage system, which takes groundwater seepage to the sump pump. Our ThermalDry vapour barrier in seen on the walls. 

Great work Jefferson, Jose and Nathan!

My issue is a leaking basement - water leaks into the basement in very heavy rainfall . I believe through the foundation walls at the back of the building and one side of the building. The building has two sump pumps but water leakage is still occurring in very heavy rainfall.

We are concerned about mould in our church basement office. Last spring we had water seep into our basement office on the carpet. It was dried up quickly and the issue appears to be fixed (overflowing eavestroughs) but there is a lingering mildew smell especially if the office is closed up for a day or two. We plan on replacing the carpet but were concerned about exposing our volunteers to mould.
