Basement Waterproofing

Your home is possibly the largest investment you may make and needs to be protected from water. Because water can enter a home in many different ways, basement waterproofing can sometimes require a multi point approach.

Foundation Cracks

Not all foundation leaks are created equal. Even just a hairline crack in your foundation will allow water to flood your basement. For this reason there are a few things you may need to do to ensure your foundation is waterproof and ready to face the elements.

Almost every basement foundation wall has cracks. Most of these foundation cracks are normal and form when concrete shrinks as it cures. However, left alone, water can penetrate even hairline foundation cracks and cause mold or other problems. Waterproofing your basement is the only way to ensure your home or building stays dry and mold free.

Interwest’s polyurethane injection system seals large or small cracks to prevent water from entering. A specially engineered polyurethane resin is injected into the crack. As the resin contacts and reacts with the water in the crack it expands up to 500% to prevent further foundation leaks. In addition, the polyurethane remains soft enough to allow for normal expansion and contraction that extends the life of your basement waterproofing project.

Basement Systems

When waterproofing foundation cracks isn’t enough, you may need to install a drainage system to keep your basement from flooding. As sub surface water levels rise they can enter your home through floor joints next to the foundation wall. By adding a floor drain system to your flooding basement, water is collected in drain pipes and directed to a sump pump. At the moment water levels reach a pre specified level, the sump pump switches on and water is pumped from the basement and relocated safely away from your home.
