Why Choose Us

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

Misclassifying a crack is the single most common mistake in this trade — treating a structural crack with the wrong material, or injecting a crack that actually needed a broader drainage fix behind it. We classify before we inject, every time.

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

An actively leaking crack rarely waits for a convenient afternoon — we prioritize dispatch for Berlin, 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 Berlin, 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

We document crack width and location with photos before and after injection so you have a record of the repair.

FAQ

What Berlin, WI Customers Ask Us Most About Foundation Crack Repair

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?▼

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?▼

A properly injected crack is unlikely to reopen at the same spot, and our work comes with a written warranty covering exactly that.

Do you provide documentation for real estate transactions?▼

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