Foundation crack repair that moves with the concrete.

Often yes. Polyurethane and epoxy injection are done from inside the basement, take a few hours, and seal the crack through the full thickness of the wall rather than just skinning over the surface. That works well for non-structural cracks in poured concrete. It is the wrong answer when hydrostatic pressure outside is the real cause, because then you are sealing a symptom while the pressure keeps working on the wall.

Epoxy is rigid and structural. It bonds the two faces of the crack back together and is used where the wall needs strength restored. Polyurethane is flexible. It expands on contact with moisture, fills irregular voids, and stays elastic so it can move with the concrete through freeze-thaw cycles without tearing. For most Edmonton water-entry cracks, polyurethane is the right choice specifically because our concrete moves so much seasonally.

A properly injected crack is a permanent repair to that crack. The material bonds through the full wall thickness and flexes with seasonal movement. What is not permanent is the situation around it: if the underlying cause is unaddressed drainage or ongoing settlement, new cracks form elsewhere. That is why we look at the whole picture before quoting a single injection.

Not immediately, but do not ignore it either. Thin vertical cracks in poured foundations are extremely common and are usually concrete shrinkage from the original cure. They matter when they start passing water, when they widen past about 3 mm, or when they grow longer over a season. Mark each end with a pencil and the date. If it moves past your marks, call.

Most single-crack injections in Edmonton fall between $500 and $1,500 depending on the length of the crack, wall thickness, and access. Multiple cracks in one visit cost less per crack. If the inspection shows the crack is a symptom of a drainage or structural problem, we tell you that instead of selling you an injection that will not solve it.

Yes, though the method changes. Poured concrete takes injection. Concrete block cracks along mortar joints and generally needs the joints repointed plus reinforcement or exterior sealing, since injection cannot fill a hollow core effectively. ICF walls need the foam removed locally to reach the concrete. We identify the wall type at the inspection and quote the correct method.
