Why Choose Us

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

Not every Marinette, 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

Misclassifying a crack is the most common mistake in this trade, and it's the first thing we check on every Marinette, WI job.

2

Fast Local Response

An actively leaking crack rarely waits for a convenient afternoon — we prioritize dispatch for Marinette, WI cracks that are currently letting water in.

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 Marinette, WI

We scope every Foundation Crack Repair job in person before quoting it, since two properties with the same symptom rarely need the same fix.

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

We also check for bowing alongside stair-step cracks, since that combination can point to a bigger structural issue.

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

Foundation Crack Repair Questions We Hear Every Week

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

Crack classification is separate from water contamination — we assess whether the crack is structural or cosmetic based on width, pattern, and any wall bowing.

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?▼

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.

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?▼

Yes — we provide before-and-after photos and a repair summary that Marinette, WI buyers, sellers, and lenders commonly request.
