Basement Crack Repair Before & After Photos

Problem: The client who resides in the town of Rosemère had a crack in her foundation and water entered during the period of snowmelt and  when there was rain. She wanted to fix this problem, as it had been going on for a while and she had tried to fix it, but unfortunately it had not worked the way she wanted.

Solution: The solution for this project was to put our product called Flexispan, this product is made from polyurethane that we inject into the crack. We then cover the crack with a polyurethane-based coating to create a beautiful light gray finish to match the coating to the concrete. Finally, we dig a small hole in front of the place where the crack is found and which will have the drainage membrane, in the event that there is water that tries to pass through the Flexispan. However, it will be redirected to the sump pump.

The FlexiSpan system is a reliable and innovative solution designed to permanently seal foundation wall cracks and prevent water from seeping into basements. FlexiSpan's unique two-part design includes a flexible polyurethane sealant that fills the crack, as well as a drainage channel that redirects any potential seepage to a drainage system. One of its key benefits is its flexibility, allowing it to adjust with foundation movement, unlike traditional rigid sealants. Additionally, it provides long-term waterproofing, ensuring that basements remain dry and protected from mold growth and further structural damage. The homeowner in Sainte-Edwidge was very satisfied with the results, knowing that the crack will no longer be a problem. 

We have repaired the wall foundation cracks in Laval against water infiltration with our FlexiSpan method. The wall cracks repaired with the FlexiSpan and the polyurethane injection if both injected, are guaranteed against infiltration for 25 years.

Our client’s basement is now waterproofed against water infiltration.

Problem: The client who lives in Lachine had a crack visible from the outside and he suspected that it was inside as well.

Solution: We injected the crack and added the Flexispan to give a nice finish. Also, we installed CarbonArmor to stabilize the foundation.

A homeowner was experiencing a crack in their foundation wall, creating a potential entry point for water infiltration and basement moisture. To address the issue, Systèmes Sous-Sol Québec repaired the crack using the FlexiSpan® system, which combines a flexible polyurethane sealant with a drainage layer designed to redirect potential water seepage toward the drainage system. This solution accommodates the natural movement of the foundation wall while helping prevent water from entering the basement through the repaired crack. The result is a targeted foundation crack repair that improves basement waterproofing and helps protect the home against recurring water infiltration.
