Epoxy and polyurethane injection for vertical, horizontal, and hairline foundation cracks. Permanent repairs with a lifetime warranty — done in one visit.
Foundation cracks are the most common source of water infiltration in Calgary homes. Our city's expansive clay soils and aggressive freeze-thaw cycle — with temperatures crossing 0°C over 100 times per year — create relentless pressure on concrete foundation walls. The result: cracks that start as hairlines and widen every winter.
Not all cracks are treated the same way. Epoxy injection is a rigid, structural-grade repair ideal for dry cracks where restoring load-bearing integrity matters. Polyurethane foam injection is flexible and moisture-activated — ideal for actively leaking cracks. We assess each crack individually before choosing a material.
We repair the crack from the interior — no excavation, no jackhammers, no landscaping destruction. Most foundation crack repairs are completed in 1–3 hours. The repaired crack is sealed through its full depth, and our lifetime warranty means if it ever leaks again, we return and fix it at no charge.
How long does the repair take? A single crack typically takes 1–2 hours. Three to four cracks in the same visit takes a half day.
Do I need to leave the house? No. All work is done from inside the basement with no disruption to other areas of the home.
Will the repair be visible? The ports are removed and the surface is patched flush. Once painted, the repair is essentially invisible.
Is the repair permanent? Yes — properly injected epoxy or polyurethane bonds chemically to the concrete and does not deteriorate. Our lifetime warranty backs every repair.
Professional injection seals a crack through its full depth — creating a bond stronger than the surrounding concrete.
