Whether it's a crack you patched yourself with hardware-store filler that's already failed, our Foundation Crack Repair team in Spring Park, MN diagnoses the real cause first and quotes a fixed price before any work begins.
📞 Speak With a Specialist
We diagnose every crack by type — vertical shrinkage, horizontal structural, stair-step settlement — before recommending a repair method, because the wrong injection chemistry on the wrong crack type doesn't hold.
Crews dispatched across Spring Park, MN typically reach an active-leak crack repair within a day or two of the call.
If a crack turns out to require carbon fiber reinforcement once opened up, we stop and requote before proceeding.
All injection ports and materials meet ICC-ES evaluated standards for foundation crack repair.
We diagnose before we quote, so the Foundation Crack Repair scope you approve is built around your property, not a generic package.
For cracks that are actively leaking, we install surface injection ports at 8 to 12 inch intervals and pump low-viscosity polyurethane resin from the lowest port upward — the foam expands on contact with water and cures flexible, sealing the full depth of the crack.
Because it cures flexible, polyurethane accommodates minor seasonal foundation movement without the seal cracking again. That precision is what keeps an injected crack from reopening at the same spot next season.

Epoxy fully bonds the two crack faces back into one structural unit, which polyurethane's flexible cure doesn't provide. Getting the chemistry and depth right the first time is what makes crack repair actually permanent.
📞 Get a Free Quote →For block or poured walls showing horizontal cracking or early inward bowing, we install carbon fiber straps anchored at the floor and rim joist — arresting further lateral movement without the cost of full excavation and replacement.
This is paired with crack injection, not used as a standalone water seal, since its job is structural stabilization. It's a step we won't shortcut, because a poorly sealed crack is worse than an untouched one.
📞 Get a Free Quote →Concrete block foundations often leak at the mortar joints rather than through the block itself — we grind out deteriorated joints to a minimum 3/4 inch depth and repack with waterproof hydraulic cement.
This addresses the most common water entry point in older block foundations that a surface coating alone can't fix. We'd rather take the extra time here than have you calling us back about the same crack.
📞 Get a Free Quote →After injection cures, we pressure-test the repair and monitor through at least one rain event where possible, confirming the seal holds before considering the job complete.
Every crack repair is documented with before/after photos as part of your written warranty file. That precision is what keeps an injected crack from reopening at the same spot next season.
📞 Get a Free Quote →Call +1-866-476-1348 and tell us whether the crack is actively leaking, its rough length, and where it's located. That routes the right technician and materials to your job.
Active leaks get priority scheduling across Spring Park; our crews typically arrive within a day or two for urgent cracks and within the week for stable ones.
The technician classifies the crack type, measures width and depth, and quotes a fixed injection price on the spot — no per-foot guessing.
Once approved, we inject the crack, verify the seal, and provide written warranty documentation covering the repaired section.
"Crack in the poured wall had been dry for two years then started weeping after a bad storm. Polyurethane injection sealed it same visit — we've had three heavy rains since with zero seepage.No regrets going with the injection over a patch."
"Had a stair-step crack in the block wall that kept getting a little wider every year. They caught it as early bowing and added carbon fiber straps along with the injection — no movement since.Exactly the fix that crack needed."
"Tried patching a crack myself with the caulk-tube stuff from the hardware store. Failed within a season. Their polyurethane injection is a completely different level — held through a full rainy season now.No regrets going with the injection over a patch."
"Mortar joints on our block foundation were the actual leak source, not a crack at all. They repointed the whole section with hydraulic cement instead of just trying to inject something that wouldn't have worked.Held up through every storm since."
Our Foundation Crack Repair coverage spans Spring Park, MN, with the same certified standard applied whether your property is in Spring Park or just outside it.
