Low-pressure injection bonds cracks from the inside out, often in a single visit.
Not every Green Lake, WI 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.
Misclassifying a crack is the most common mistake in this trade, and it's the first thing we check on every Green Lake, WI 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.
Polyurethane expands to fill voids behind an actively weeping wall; epoxy is reserved for cracks that need structural bonding.
We scope every Foundation Crack Repair job in person before quoting it, since two properties with the same symptom rarely need the same fix.
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.
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.
Fast turnaround matters during a real estate transaction, and we prioritize scheduling for time-sensitive pre-sale repairs.
Tell us the crack's location, whether it's actively leaking, and roughly how wide it is so we can bring the right materials.
We also check the exterior grading near the crack, since poor drainage is often what caused it in the first place.
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."
— Green Lake Seller
"Polyurethane injection stopped an active leak the same day they showed up — didn't expect it to be that fast."
— Green 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."
— Green Lake Customer
"Stair-step crack in our block wall had us worried about the whole foundation. Turned out to be isolated and fixable with injection."
— Green Lake 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.
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.
If new movement occurs elsewhere in the wall, that's a separate issue we'd assess independently.
Yes — we provide before-and-after photos and a repair summary that Green Lake, WI buyers, sellers, and lenders commonly request.
