Concrete Leveling

For most jobs, yes. Polyurethane foam weighs about 2 lbs per cubic foot vs. 100+ lbs for mud slurry, so it doesn't add load to the already-weak soil that caused the settlement. The injection holes are dime-sized vs. quarter-sized. Foam is waterproof and won't wash out. And foam cures in 15 minutes — you can drive on a lifted driveway the same day.

Foot traffic: about 15 minutes after injection. Vehicle traffic on driveways: same day, usually within 2 hours. Heavy equipment or pool refilling: next day. The polyurethane reaches 90% of its final strength within minutes of injection — that's the main advantage over mudjacking, which needs days to cure.

Replace when the concrete itself is structurally failed — spalled badly, crumbling at the edges, or cracked into multiple separated pieces that no longer act as a slab. Lifting works on intact slabs that have settled. If we inspect and replacement is the better call, we'll tell you straight; we don't push a foam job that won't last.

No, when it's done by an experienced crew. We map utilities and pool plumbing before drilling, use ports far from the concerned areas, and control foam expansion in real time. Foam injected near pools and patios doesn't damage liners or coping when placed correctly.

When the underlying cause is addressed, polyurethane foam leveling is a long-term fix. The foam is waterproof, doesn't wash out, and won't lose volume the way old mudjacking slurry can. For most driveways, patios, and walkways, a properly lifted slab stays level for many years.

Almost always. Leveling typically costs a fraction of tear-out and replacement, is finished in hours instead of days, and lets you use the surface the same day. Replacement only makes sense when the concrete itself is severely cracked or crumbling beyond repair.

Driveways, sidewalks, patios, pool decks, garage floors, basement floors, porch steps, and interior slabs. If a slab has sunk, settled, or developed a trip hazard, polyurethane foam injection can usually raise it back to level.
