Small drill holes are all it takes. Polyurethane concrete raising lifts sunken sidewalks by injecting foam beneath the slab—no demolition, no mess, and no waiting days to use your concrete again.

Most sunken concrete is not unsafe or “broken”—it’s simply settled.
If your sidewalk, driveway, steps, patio, or garage apron is uneven but not cracked beyond repair, polyurethane concrete raising is usually the faster, cleaner, and far more cost-effective solution than full replacement.

Concrete sinking starts small—tiny gaps, new cracks, or water pooling where it shouldn’t. This guide shows Minnesota homeowners how to identify early signs of slab settlement before it becomes a costly replacement. Benchmark Concrete Raising explains what to look for and when to call for a free evaluation.

Wondering whether to repair, resurface, or replace your concrete driveway? Benchmark Concrete Raising breaks down each option in plain language.
