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

Misclassifying a crack is the single most common mistake in this trade — treating a structural crack with the wrong material, or injecting a crack that actually needed a broader drainage fix behind it. We classify before we inject, every time.
Misclassifying a crack is the most common mistake in this trade, and it's the first thing we check on every Prior Lake, MN job.
Most crack injection appointments can be scheduled within a day or two of your call.
Pricing is based on crack length and injection material, quoted in writing before we drill any injection ports.
We carry both structural epoxy and flexible polyurethane so the crew can match material to the crack on the same visit.

Every Prior Lake, MN Foundation Crack Repair job starts with an inspection, not a generic package — here's what that typically includes.
Structural cracks that aren't actively leaking get epoxy injection, which bonds the concrete back together rather than just sealing the surface.
Polyurethane cures even in the presence of water, which makes it the right call for a crack that's actively letting water through.
We also check for bowing alongside stair-step cracks, since that combination can point to a bigger structural issue.
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.
A technician measures crack width, checks for wall bowing, and determines whether it's structural, cosmetic, or actively leaking.
We explain why we're recommending one material over the other so the choice isn't a black box.
We check the injection ports after curing to confirm the material fully filled the crack before we consider the job done.

"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."
— Prior Lake Seller
"They explained why our crack was structural and not just cosmetic, which the previous contractor never bothered to check."
— Prior Lake Homeowner
"Had two cracks — one needed epoxy, one needed polyurethane. They matched material to each one instead of using the same thing on both."
— Prior Lake Customer
"Fast, clean work — no mess left behind after the injection ports were patched."
— Prior Lake Homeowner
Active leaks get flexible polyurethane regardless of classification, since stopping water intrusion is the immediate priority.
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.
Multiple cracks or hard-to-access areas can extend the timeline, which we'll flag in the written quote.
If new movement occurs elsewhere in the wall, that's a separate issue we'd assess independently.
Turnaround is usually fast enough to fit within a typical closing timeline.
