Leaking and Wet Basement Walls

Cracked, leaking basement walls decrease the comfort, value  and safety of your home. Water will have an easier way through these cracks to create moisture problems in your basements, contributing to foundation damage, mold growth and other related issues. 

Materials that are porous or let water in, like concrete walls, act like sponges in that water and vapor can seep and sink through the porous material and into your basement. If you've had concrete that was damp and a few days later dried, this has happened to you.

Our basement leaking solutions

A waterproof seal. Prevent future leaks with our basement window sealing system.

• Floor cracks: Water can rise directly through the porous concrete of your floor slab, a problem that's exacerbated when there's a crack. When you have water coming through the floor, the first step is installing a perimeter drain system. We can also install a direct drainage channel, which will help direct any water that comes through the crack into the drain and your sump pump. Finally, we will backfill the crack with stone and cover it with fresh concrete to prevent future leaks.
• Wall cracks: The soil around your foundation is filled with water, and even the smallest crack will allow this groundwater to seep into your basement. Much like with floor cracks, the first step to repairing a leaky wall crack is installing one of our drainage systems. We then use an innovative polyurethane sealant called FlexiSpan® to seal the crack. This flexible sealant will never dry or crack and can flex to the natural movement of your foundation wall, ensuring a completely waterproofing seal.
• Leaky windows: Window frames break down over time, creating separation and allowing water to seep past seals. Once again, the first step for repairing window leaks is a drainage system that funnels the water to your sump pump. We will then create a small hole in the wall under the window with a plastic fitting that directs any water into the drainage system. This is then sealed with a polymer injection for a clean, waterproof finish.
