Low-pressure injection bonds cracks from the inside out, often in a single visit.

Not every Potwin, KS 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 Potwin, KS job.
An actively leaking crack rarely waits for a convenient afternoon — we prioritize dispatch for Potwin, KS 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 Potwin, KS 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.
We explain why we're recommending one material over the other so the choice isn't a black box.
Most single-crack injections are completed in a few hours, start to finish, in one visit.
