Foundation Crack Repair & Crack Injection
Cracks that leak, spread, or keep coming back after a patch — sealed at the source with injection built to flex and hold.
What It Is
Foundation Crack Repair & Crack Injection
For homeowners with a cracked or leaking foundation wall: we inject and seal the crack itself, so water and movement stop where they start.
Foundation crack repair fixes the crack at full depth instead of skimming the surface. Active, water-bearing cracks in poured concrete take a flexible polyurethane resin that fills the entire thickness of the wall and stays elastic enough to move with seasonal shifts. Structural cracks that need the concrete re-bonded take a rigid epoxy that knits the two faces back together. Matching the resin to the crack is the difference between a repair that holds and a patch that reopens.
A surface patch fails because it never reaches the cause. Across Kansas, Oklahoma, Missouri, and Arkansas, expansive clay soils swell when wet and shrink when dry, and that constant movement — plus water pressure against the wall — is what drives cracks open again. We diagnose why the crack formed before we seal it, so the fix addresses the source, not just the symptom.
Signs you need crack repair
- A crack that leaks or weeps after heavy rain
- A patched crack that has reopened
- Vertical or diagonal cracks in a poured wall
- White mineral crust (efflorescence) around a crack
- A visible gap, daylight, or draft through a crack
- A crack that has widened over months
How We Fix It
How we seal a foundation crack
| Your situation | What we do |
|---|---|
| Active, leaking crack in poured concrete | Flexible polyurethane injection that fills the full depth of the wall and flexes with seasonal movement. |
| Structural crack that needs the concrete re-bonded | Rigid epoxy injection that knits the two faces of the crack back into one wall. |
| Crack driven by soil pressure against the wall | We treat the cause too — injection paired with drainage or wall stabilization when the wall is moving. |
| Recurring crack a surface patch didn't hold | Full-depth injection from the inside, not a cosmetic skim that cracks again next season. |

Frequently Asked Questions

Call or text (620) 719-7366Will crack injection stop a leak for good?
When the crack is the water's path, a full-depth polyurethane injection seals it and stays flexible enough to hold through seasonal movement. If outside water pressure or poor drainage is forcing water against the wall, we address that too — sealing the crack without relieving the pressure only sends the water to the next weak point.
Epoxy or polyurethane — which does my crack need?
It depends on the crack. Polyurethane stays flexible and is the usual choice for active or leaking cracks that still move. Epoxy is rigid and bonds the concrete back together where the crack needs structural strength. We assess the crack on site and use the resin that matches it.
Do you repair cracks in block walls, not just poured concrete?
Yes. Block and poured walls crack differently and are sealed differently, and some block-wall cracks signal soil pressure rather than a simple crack. We identify what the wall is doing before recommending injection on its own or paired with stabilization.
Is a foundation crack serious?
Some are cosmetic and some signal movement. A hairline vertical crack is often shrinkage, while horizontal cracks and cracks that widen or leak deserve prompt attention. Our free consultation tells you which kind you have — no pressure, just a straight answer.
