Foundation Crack Repair in Niagara
Assessment and repair of vertical, diagonal and stair-step foundation cracks in poured and block walls.
How It Works
Free Crack Inspection
We inspect the crack from inside the basement, check for signs of movement or structural concern, and confirm whether injection is the right repair before anything is booked.
Crack Preparation
The crack is cleaned along its full length, surface ports are set at regular intervals, and the face of the crack is sealed with epoxy paste so the injection material stays inside the wall.
Injection
Epoxy or polyurethane is injected port by port from the bottom up until the crack is filled through the full thickness of the wall, not just at the surface.
Verification & Warranty
We confirm the crack is filled end to end, remove the ports, and walk you through the finished repair. Your injection is backed by a written warranty against leaking.
Frequently Asked Questions
Are foundation cracks normal?
Hairline shrinkage cracks are common in poured concrete foundations as the concrete cures. Most are not structural, but any crack that leaks, widens over time, or runs in a stair-step pattern through block or brick should be assessed by a professional.
When is a foundation crack a structural problem?
Warning signs include horizontal cracks, stair-step cracks in block walls, cracks wider than a few millimetres, walls that bow inward, and cracks that keep growing. These point to soil pressure or settlement and need an assessment before any cosmetic repair.
Can a cracked foundation be repaired without digging?
Yes, in most cases. Cracks in poured concrete walls can be injected from inside the basement with epoxy or polyurethane, filling the crack through the full thickness of the wall with no excavation.
Will the crack come back after repair?
A properly injected crack is filled through the full depth of the wall and should not leak again, and our repairs carry a written warranty against leaking. New cracks can form in other areas, so we inspect the full foundation while on site.
