Wall cracks are very common in concrete foundation walls. To solve the problem, you need a solution that can adapt to future wall movements, because products that become rigid will crack again or lose their adhesion to concrete. This process will start again as long as the problem is not resolved with the right solution. The FlexiSpan solution seals the crack and provides a second repair strategy in the event that the sealant fails. FlexiSpan Sealant is a rubber-like liquid that allows the material to adapt to the movement of the crack. It is flexible and will not peel off concrete. It blocks water permanently.

Job Stories From Saint-denis-sur-richelieu, QC
A sagging house in Saint-Denis-Sur-Richelieu, Qc

This homeowner had a house in Saint-Denis-sur-Richelieu noticed that he had wall cracks on his wall foundation, which also started to crack!

In order to solve this problem, he contacted us to express his concerns, and we sent our specialist who recommended the installation of galvanized steel Push Pier support piles,   the FlexiSpan sealant for the repair of this crack and the SupportWorks support pillars which are the best solution to move the house back to its original position.

The PushPiers system allows the weight of the house to be transferred to pillars that sit and are fixed to the solid bedrock. Thus, the foundations are stabilized permanently.

As for the FlexiSpan, it is an injected liquid which, once dry, becomes rubbery and adapts to the movements of the floor and wall.

 This installation project requires only minimal disruption and is completed quickly compared to other solutions.

 Moreover, our client’s the problem is solved once and for all.
