Unionville, PA's Foundation Crack Repair Specialists: Seal It Before It Widens

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 Unionville, PA Property Owners Choose SGP Waterproofing for Foundation Crack Repair

Not every Unionville, PA 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

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

3

Flat-Rate Injection Pricing

A single crack repair is one of the most predictably priced jobs we do — no surprise scope creep.

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

The Full Scope of Our Unionville, PA Foundation Crack Repair Work

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

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

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.

How It Works

Our Four-Step Foundation Crack Repair Dispatch Process

01

Call & Crack Description

Photos texted ahead of time help us prep for the visit and sometimes speed up scheduling.

02

On-Site Crack Classification

We also check the exterior grading near the crack, since poor drainage is often what caused it in the first place.

03

Written Injection Quote

You'll get a price based on crack length and material — epoxy or polyurethane — before any drilling starts.

04

Injection & Cure Verification

We check the injection ports after curing to confirm the material fully filled the crack before we consider the job done.

FAQ

What Unionville, PA 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?

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?

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?

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