Benefits of Polyurethane Foam
Why we lift concrete with high-density polyurethane foam — and what it means for your driveway, sidewalk or patio.
Light, strong, waterproof
Polyurethane lifting foam is injected as a liquid, expands to fill the voids under your slab, and hardens into a dense, load-bearing structure in about 15 minutes. Because it’s lightweight, it won’t overload the very soil that settled in the first place. Because it’s waterproof, it won’t wash out like mud slurry can. And because it cures fast, you’re back on your concrete the same day.
It goes in through small, dime-sized ports that we fill and seal, so there’s almost nothing to patch. For driveways, sidewalks, patios, garage and basement floors across the Denver metro, it’s the cleanest, longest-lasting way to get concrete back to level — for a fraction of replacement.
