Structural or Leaking? Foundation Crack Repair in Centreville, IL, Classified and Fixed

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.

Why Choose Us

Why Centreville, IL Property Owners Choose SGP Waterproofing for Foundation Crack Repair

Not every Centreville, 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.

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 Centreville, IL job.

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 Centreville, IL

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

Crack Repair

Low-Pressure Epoxy Injection

Epoxy-injected cracks regain much of their original structural strength, which matters for load-bearing foundation walls.

Crack Repair

Polyurethane Injection for Active Leaks

Polyurethane cures even in the presence of water, which makes it the right call for a crack that's actively letting water through.

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.

Crack Repair

How It Works

Our Four-Step Foundation Crack Repair Dispatch Process

Call & Crack Description

Tell us the crack's location, whether it's actively leaking, and roughly how wide it is so we can bring the right materials.

02

On-Site Crack Classification

03

Written Injection Quote

04

Injection & Cure Verification

Most single-crack injections are completed in a few hours, start to finish, in one visit.

FAQ

Foundation Crack Repair Questions We Hear Every Week

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?

Multiple cracks or hard-to-access areas can extend the timeline, which we'll flag in the written quote.

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 Centreville, IL buyers, sellers, and lenders commonly request.
