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 Knightstown, IN 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 Knightstown, IN job.
An actively leaking crack rarely waits for a convenient afternoon — we prioritize dispatch for Knightstown, IN 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 Knightstown, IN 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.
Cracks that are still weeping get flexible polyurethane, which expands into voids and stays flexible enough to handle minor seasonal movement.
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.
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 Knightstown, IN home with a flagged foundation crack? We can inspect, repair, and provide documentation for the buyer's lender or inspector.
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.
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."
— Knightstown Seller
"They explained why our crack was structural and not just cosmetic, which the previous contractor never bothered to check."
— Knightstown Homeowner
"Had two cracks — one needed epoxy, one needed polyurethane. They matched material to each one instead of using the same thing on both."
— Knightstown Customer
"Stair-step crack in our block wall had us worried about the whole foundation. Turned out to be isolated and fixable with injection."
— Knightstown 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.
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.
Turnaround is usually fast enough to fit within a typical closing timeline.
