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!

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.

Problem: An unfinished cold storage area is a great place to store items to keep cool, such as canned food, even in the warm summer months. Although closed off from the rest of the house, if there’s water penetrating any area, it creates a damp, humid and unhealthy environment which affects the entire home in what is known as “The Stack Effect”.    

Solution:  We installed a French drain system on the problem walls in the cold storage area, added a powerful sump pump with a battery backup for improved drainage and reliability and finished it off with our BrightWall® rigid basement wall system. Now this cold storage area is dry, heathy and will look fantastic for years to come.

In the unfinished area of the basement, we created an in-floor drain which effectively moves any and all leaking water into their new heavy-duty sump pump system. We then finished the floor with fresh concrete. This area is now a clean and dry space for storage - just what the homeowners wanted!

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.

I just found three separate small puddles in my basement. Two are away from walls. One was at the base of a wall. No water can be seen dripping from above. Bubbles have formed in the floor paint. So, I suspect its water seeping in from below. My wife and I just bought the house. There's evidence of an existing sump pit but I can't identify a pump.
