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 Dunlap, IL 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 Dunlap, IL job.
An actively leaking crack rarely waits for a convenient afternoon — we prioritize dispatch for Dunlap, IL 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 Dunlap, IL 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.
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.
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.
We check the injection ports after curing to confirm the material fully filled the crack before we consider the job done.

We repair cracks of nearly any size — hairline cracks are often the easiest and cheapest to seal before they widen further.
We make the call on-site after inspecting the crack, not before we've seen it.
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.
