We classify every crack before injecting it — structural cracks get epoxy, active leaks get flexible polyurethane, and both get a written scope before we start.
Not every Dayton, 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.
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.
Polyurethane expands to fill voids behind an actively weeping wall; epoxy is reserved for cracks that need structural bonding.
Every Dayton, 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.
Vertical cracks are usually settlement-related and often isolated; horizontal cracks can indicate hydrostatic pressure pushing on the wall and get flagged for further evaluation.
Selling a Dayton, MN home with a flagged foundation crack? We can inspect, repair, and provide documentation for the buyer's lender or inspector.
Tell us the crack's location, whether it's actively leaking, and roughly how wide it is so we can bring the right materials.
A technician measures crack width, checks for wall bowing, and determines whether it's structural, cosmetic, or actively leaking.
You'll get a price based on crack length and material — epoxy or polyurethane — before any drilling starts.
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."
— Dayton Seller
"Polyurethane injection stopped an active leak the same day they showed up — didn't expect it to be that fast."
— Dayton Homeowner
"Appreciated the before-and-after photos for our records in case we ever need them for a future sale."
— Dayton Customer
"Stair-step crack in our block wall had us worried about the whole foundation. Turned out to be isolated and fixable with injection."
— Dayton 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.
Epoxy is better for structural bonding on a non-leaking crack; polyurethane is better for a crack that's actively weeping since it cures even with water present.
Most single-crack injections are completed in a few hours during one visit.
If new movement occurs elsewhere in the wall, that's a separate issue we'd assess independently.
