Basement Crack Repair Before & After Photos

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 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.

If you are concerned like this customer from Candiac because you see signs of efflorescence, moisture, and water seepage and you see a crack in your concrete wall, do not wait too long before you act. The more you neglect the problem, the more it gets worse. Indeed, a crack brought water and water vapor into the subsoil causing the appearance of efflorescence. In addition, sealing a crack with rigid products such as epoxy is not a long-term solution, because as the wall cracks move, the sealant will break and fall or the crack will reappear at another location, and the problem of water and humidity will come up again. To fix the problem, we inject our patented FlexiSpan sealant which is a urethane-based liquid that, and once dry, will be flexible to block the vapors and water infiltrations and resist the movement of the wall crack

Below you can find our before and after pics in this basement in La Prairie.

In the before photo, you can see the danger inside this basement in Montreal incarnated by a big crack causing water infiltration. With walls seemingly under siege by water, the sense of urgency was palpable. Here's where we stepped in. As depicted in the vivid contrast of the after photo, we employed FlexiSpan—a hallmark of durability in our arsenal—effectively turning a damp, worrisome space into a dry, serene sanctuary. Through our dedicated intervention, the nightmare of a leaking basement was transformed into peace of mind.
