Wall Crack Repair

Foundation cracks are a common—and leaky—problem. We seal them permanently from the inside with professional injection, no digging required.

The Solution

Permanent crack sealing without tearing up your yard.

Foundation cracks let water seep in and, over time, can widen and worsen. We repair them using professional polyurethane or epoxy injection—a process that fills the crack completely, from the inside face all the way through the wall.

Polyurethane injections stay flexible, sealing against water while allowing for the natural movement of your foundation. Epoxy injections restore structural strength to the wall. We choose the right material based on the type and cause of the crack.

The entire repair is done from inside your basement, so there's no excavation, no landscaping damage, and no lengthy disruption. Most crack repairs are completed in a single visit.
