How Long Does Concrete Lifting Last?

The short answer: with polyurethane foam, effectively forever. Here's what determines longevity — and what doesn't.

Polyurethane foam is chemically inert and waterproof. It doesn't absorb moisture, doesn't break down in soil, and doesn't shrink over time — the same reason it's used as structural fill beneath highways and airport runways. That's a meaningful difference from older cement-slurry methods, as we cover in polyurethane foam vs. mudjacking.

That said, concrete leveling only addresses the void that existed at the time of the repair. If a downspout keeps dumping water against the foundation, or a broken drain line keeps eroding soil, a new void can form somewhere else — our guide to downspouts and slab settlement walks through the fix. Fix the cause and the lift on your driveway lasts.

Every reputable concrete leveling contractor will back their work with a written warranty. Read the terms — the length and what's covered — before signing. Homeowners across Spokane and the surrounding communities can request a free written estimate and review the warranty language up front.
