Concrete Repair Done Right

Crack Repair & Injection

Hairline cracks, structural cracks, and active leaks. We use polyurethane and epoxy injection systems plus surface routing and sealing to stop water and stabilize the slab.

Slab Jacking & Leveling

If your driveway, sidewalk, or patio has settled or sunk, we can lift it back into place using polyurethane foam injection or traditional mud jacking — far cheaper than tear-out and replacement.

Spalling, Patching & Step Repair

Surface flaking from salt and freeze-thaw damage, broken edges, damaged steps, and crumbling corners can all be repaired with polymer-modified patching compounds and bonding agents.

Joint Sealing

Failing expansion and control joints let water under your slab — the #1 cause of cracking and settlement. We clean and re-seal joints with flexible, weather-resistant sealants.

Concrete Repair FAQs

How much does concrete repair cost in Janesville, WI?

Small crack repairs and joint sealing typically start around $300–$600. Slab jacking and mud jacking for sunken driveways or sidewalks usually runs $500–$1,500+ per slab depending on lift height and access. Full section replacement is priced per square foot. We provide free, written quotes.

Should I repair my concrete or replace it?

If the underlying slab is structurally sound and the issues are surface-level (hairline cracks, spalling, joint failure, minor settlement), repair is usually 30–50% the cost of replacement. If there's deep structural cracking, severe settlement, or failed sub-grade, replacement is the smarter long-term call.

How long does concrete repair work take to cure?

Most polymer-modified patching compounds and crack injection products are walkable in 4–24 hours and ready for full use in 24–72 hours. Slab jacking with polyurethane foam can typically be driven on within 15–30 minutes. We'll give you specific cure times on your project.

Will repaired cracks come back?

Not when the root cause is addressed. We diagnose what's actually causing the failure — water infiltration, poor drainage, settlement, freeze-thaw — and fix that first, then repair the visible damage. Cosmetic-only patches without addressing the cause are why most repairs fail within a year.
