Low-pressure injection bonds cracks from the inside out, often in a single visit.

Not every Minneapolis, MN foundation crack needs the same material or approach. A vertical settlement crack behaves differently than a stair-step block crack, and we adjust injection technique and material to match what's actually happening in the wall.
Our technicians are trained to tell a cosmetic hairline crack apart from one that signals structural movement, before recommending a fix.
An actively leaking crack rarely waits for a convenient afternoon — we prioritize dispatch for Minneapolis, MN cracks that are currently letting water in.
Pricing is based on crack length and injection material, quoted in writing before we drill any injection ports.
Polyurethane expands to fill voids behind an actively weeping wall; epoxy is reserved for cracks that need structural bonding.

Every Minneapolis, MN Foundation Crack Repair job starts with an inspection, not a generic package — here's what that typically includes.
Epoxy-injected cracks regain much of their original structural strength, which matters for load-bearing foundation walls.
Polyurethane cures even in the presence of water, which makes it the right call for a crack that's actively letting water through.
Stair-step cracking in block foundation walls needs a different injection port pattern than a vertical crack in poured concrete, and we adjust technique accordingly.
We document crack width and location with photos before and after injection so you have a record of the repair.
Fast turnaround matters during a real estate transaction, and we prioritize scheduling for time-sensitive pre-sale repairs.

Photos texted ahead of time help us prep for the visit and sometimes speed up scheduling.
We also check the exterior grading near the crack, since poor drainage is often what caused it in the first place.
We explain why we're recommending one material over the other so the choice isn't a black box.
Most single-crack injections are completed in a few hours, start to finish, in one visit.

"Crack in our basement wall had been leaking for a year before we finally called. Injection took less than an afternoon and it's been dry since."
— Minneapolis Seller
"Polyurethane injection stopped an active leak the same day they showed up — didn't expect it to be that fast."
— Minneapolis Homeowner
"Had two cracks — one needed epoxy, one needed polyurethane. They matched material to each one instead of using the same thing on both."
— Minneapolis Customer
"Fast, clean work — no mess left behind after the injection ports were patched."
— Minneapolis Homeowner
Crack classification is separate from water contamination — we assess whether the crack is structural or cosmetic based on width, pattern, and any wall bowing.
We repair cracks of nearly any size — hairline cracks are often the easiest and cheapest to seal before they widen further.
We make the call on-site after inspecting the crack, not before we've seen it.
Most single-crack injections are completed in a few hours during one visit.
A properly injected crack is unlikely to reopen at the same spot, and our work comes with a written warranty covering exactly that.
Yes — we provide before-and-after photos and a repair summary that Minneapolis, MN buyers, sellers, and lenders commonly request.
