Foundation Crack Repair in Mississauga
Leaking cracks sealed permanently, from inside or from the outside of the wall, depending on what the crack needs.
Stop the Crack From Leaking
Foundation walls crack as they cure and as the ground moves, and every spring thaw pushes water through them. We assess the crack, then seal it the right way: injection from inside, or excavation with repair, coating and membrane on the outside for bigger problems.

Questions
Is my crack serious?
Thin vertical cracks are usually shrinkage. They aren't structural, but they will leak. Wide, horizontal or stepped cracks need to be looked at in person.
Inside or outside repair?
Most single cracks can be injected from inside. If the wall has wider damage, an exterior repair with membrane lasts longer.
How long does it take?
Interior injection usually takes a few hours. Exterior repairs are typically done in a day or two.
