Basement Floor & Wall Crack Repair in the Province of Quebec

Repair Flooding, Leaking Cracks in Your Basement or Crawl Space

When water starts to leak through your basement walls or floors, it can quickly lead to a very serious flood in your home.

At Systèmes Sous-sol Québec, we provide a variety of repair products and techniques -- each designed specifically to take on a different source of leaks in the foundation walls and basement's concrete floors.

Our Crack Repair Services

The crack repair systems we use are based on the time-tested best practices in the industry.

Several of our warrantied methods are patented and/or award-winning techniques that have been used in thousands of homes worldwide.

These methods include polyurethane injection, which seals the cracks inside-out, and FlexiSpan®, which seals the crack as a secondary line of defense and provides a hidden drain channel should any leakage reoccur. In our experience, a combination of polyurethane injection and FlexiSpan® is the ultimate solution.

Polyurethane injection goes deep into the cracked wall, unlike methods that merely patch the wall surface. It involves boring injection holes at 45° so the borings intersect with the crack about halfway through the wall. Injection ports are installed and polyurethane resin is pumped through the depth of the crack to the soil outside.

FlexiSpan®, a system that your technician may use in combination with polyurethane injection, offers additional security against future leaks. In the event of minor seepage that manages to penetrate the poly injection seal, a foam strip and durable coating over the crack create a surface channel that transports moisture to a perimeter drainage system.

Our Services Include:

Repairing Leaking Cracks

Water can enter your home at any point where there is an opening in the foundation. This includes not only cracks in the walls and floors, but around pipes as well.

Our solutions provide lasting results that are compatible with your perimeter drainage system and will not crumble, flake off your walls, or fail due to the natural expansion and shrinking of the concrete.

We service Quebec, including Montreal, Quebec City, Laval, Joliette, Gatineau, Longueuil, Sherbrooke, and nearby areas. Contact us today for a free wall crack repair quote!
