Foundation Crack Injection Process

Here's Exactly What We Do

First, we inspect your foundation to identify all problem areas, not just the obvious ones. We look for the root cause, not just the symptoms you can see.

Next, we prepare each crack by cleaning out loose material and debris. Then we inject professional-grade polyurethane or epoxy resin under pressure. This material expands to fill the entire crack and creates a flexible, waterproof seal.

The repair cures within hours, but we recommend waiting 24 hours before any heavy moisture exposure. You’ll have a permanent repair that moves with your foundation and keeps water out.

More Than Just Crack Filling

You get a complete foundation assessment, not just a quick fix. We identify why the cracks formed and address underlying drainage issues when needed.

Our crack injection uses commercial-grade materials designed for Long Island’s soil conditions. The repair comes with a warranty because we use methods that actually work long-term.

We also handle basement wall crack repair, foundation leak repair, and structural integrity issues. If your foundation needs more than crack repair, we’ll tell you upfront and explain your options clearly.

Most foundation crack repairs take 2-4 hours depending on the number and size of cracks. The injection material cures quickly, but we recommend waiting 24 hours before exposing the area to moisture. You can use your basement normally right after we finish, but avoid pressure washing or flooding the area for a day. The repair reaches full strength within 48 hours.
A properly done crack injection creates a seal that’s actually stronger and more flexible than the surrounding concrete. The repair moves with your foundation as it settles, preventing new cracks from forming in the same spot. However, if underlying issues like poor drainage aren’t addressed, new cracks can form elsewhere. That’s why we always check for root causes during our assessment.
Foundation crack repair costs depend on the number, size, and location of cracks. Most homeowners spend between $300-800 for typical crack injection repairs. Structural cracks or those requiring excavation cost more. We provide upfront pricing after inspecting your foundation, so you know exactly what you’re paying before we start work. No surprise charges or hidden fees.
DIY crack fillers from hardware stores are temporary patches that typically fail within 1-2 years. They can’t be injected under pressure and don’t bond properly with concrete. Professional crack injection uses commercial-grade materials and specialized equipment to create permanent repairs. Attempting DIY repairs often makes professional repair more difficult and expensive later.
Not all foundation cracks indicate serious structural issues. Small settling cracks are normal in most homes. However, horizontal cracks, stair-step patterns, or cracks wider than 1/4 inch can signal structural problems that need immediate attention. We evaluate each crack’s pattern, size, and location to determine if it’s cosmetic or structural, then recommend appropriate repairs.
Epoxy injection works best for structural repairs and dry cracks. It’s rigid and creates a very strong bond. Polyurethane is better for active leaks and cracks that might move slightly, as it stays flexible and expands to fill gaps. We choose the right material based on your specific crack type, whether water is present, and your foundation’s movement patterns.
