Why Choose Us

Why Markesan, WI Property Owners Choose SGP Waterproofing for Foundation Crack Repair

Not every Markesan, 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.

1

Licensed Crack Classification

Our technicians are trained to tell a cosmetic hairline crack apart from one that signals structural movement, before recommending a fix.

2

Fast Local Response

Most crack injection appointments can be scheduled within a day or two of your call.

3

Flat-Rate Injection Pricing

Pricing is based on crack length and injection material, quoted in writing before we drill any injection ports.

4

Epoxy & Polyurethane Both On the Truck

Polyurethane expands to fill voids behind an actively weeping wall; epoxy is reserved for cracks that need structural bonding.

What We Do

Comprehensive Foundation Crack Repair Solutions in Markesan, WI

Every Markesan, WI Foundation Crack Repair job starts with an inspection, not a generic package — here's what that typically includes.

Crack Repair

Low-Pressure Epoxy Injection

Structural cracks that aren't actively leaking get epoxy injection, which bonds the concrete back together rather than just sealing the surface.

Crack Repair

Polyurethane Injection for Active Leaks

Cracks that are still weeping get flexible polyurethane, which expands into voids and stays flexible enough to handle minor seasonal movement.

Crack Repair

Stair-Step Block Crack Repair

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.

Crack Repair

Vertical & Horizontal Wall Crack Sealing

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.

FAQ

Frequently Asked Questions About Foundation Crack Repair

How do you classify contaminated water versus a structural crack repair?

Active leaks get flexible polyurethane regardless of classification, since stopping water intrusion is the immediate priority.

Will you repair hairline cracks or only large ones?

We repair cracks of nearly any size — hairline cracks are often the easiest and cheapest to seal before they widen further.

Is epoxy or polyurethane better for my crack?

We make the call on-site after inspecting the crack, not before we've seen it.

How long does crack injection take?

Most single-crack injections are completed in a few hours during one visit.

Will the crack reopen after injection?

If new movement occurs elsewhere in the wall, that's a separate issue we'd assess independently.

Do you provide documentation for real estate transactions?

Turnaround is usually fast enough to fit within a typical closing timeline.
