Is Polyurethane Foam Lifting a Permanent Fix for Sinking Concrete Slabs?

Under the right conditions, Polyurethane Foam Lifting can provide a durable, long-term solution for sinking concrete slabs. Our experience shows that when the underlying soil is stable and the slab is not exposed to ongoing moisture or erosion, this method can function as a permanent fix. Unlike traditional mudjacking, which uses a heavy slurry that can wash out or add weight to the soil, polyurethane foam is lightweight, non-porous, and naturally resists erosion.

While polyjacking is highly effective, its longevity depends on a few key factors:

  • Superior Durability: The closed-cell foam we use is impermeable to water, which eliminates the freeze-thaw damage and moisture erosion that often undermine other repair methods.
  • Immediate Stability: The material cures in minutes and provides immediate load-bearing capacity, meaning there is no downtime for your property.
  • Expert Installation: As a family-owned and operated business since 1996, we emphasize that a truly permanent fix requires a professional soil assessment. In some cases, if settlement is caused by deep structural failure rather than surface-level soil voids, we may recommend Helical Piers instead of foam lifting.
