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 Delphi, 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 Delphi, IN job.
An actively leaking crack rarely waits for a convenient afternoon — we prioritize dispatch for Delphi, 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 Delphi, 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.
Polyurethane cures even in the presence of water, which makes it the right call for a crack that's actively letting water through.
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.
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.

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.

"We were selling the house and the inspector flagged a foundation crack. They came out within two days, injected epoxy, and gave us documentation for the buyer's lender."
— Delphi Seller
"Polyurethane injection stopped an active leak the same day they showed up — didn't expect it to be that fast."
— Delphi Homeowner
"Appreciated the before-and-after photos for our records in case we ever need them for a future sale."
— Delphi Customer
"Fast, clean work — no mess left behind after the injection ports were patched."
— Delphi Homeowner
Crack classification is separate from water contamination — we assess whether the crack is structural or cosmetic based on width, pattern, and any wall bowing.
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 Delphi, IN buyers, sellers, and lenders commonly request.
