Structural or Leaking? Foundation Crack Repair in Corunna, MI, Classified and Fixed
Low-pressure injection bonds cracks from the inside out, often in a single visit.
Low-pressure injection bonds cracks from the inside out, often in a single visit.
Not every Corunna, MI 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 Corunna, MI cracks that are currently letting water in.
A single crack repair is one of the most predictably priced jobs we do — no surprise scope creep.
We carry both structural epoxy and flexible polyurethane so the crew can match material to the crack on the same visit.
Every Corunna, MI 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.
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.
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."
— Corunna Seller
"Polyurethane injection stopped an active leak the same day they showed up — didn't expect it to be that fast."
— Corunna Homeowner
"Had two cracks — one needed epoxy, one needed polyurethane. They matched material to each one instead of using the same thing on both."
— Corunna Customer
"Stair-step crack in our block wall had us worried about the whole foundation. Turned out to be isolated and fixable with injection."
— Corunna Homeowner
Active leaks get flexible polyurethane regardless of classification, since stopping water intrusion is the immediate priority.
Catching a crack early with injection usually costs less than waiting until it's actively leaking.
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.
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.
