The causes of concrete settlement and sinking are the same whether it's a driveway, walkway, patio, garage floor, or pool deck. As soil underneath a concrete slab shrinks, settles or washes away, this leaves empty space, or voids, beneath the slab. With the soil no longer supporting the slab, the concrete will sink, creating an uneven surface.
PolyLevel uses a high-density polyurethane foam to fill voids and stabilize and lift sinking concrete slabs. The expanding properties of the two-part urethane formula allows for accurate leveling of the slab. The result is a waterproof repair that's much more permanent than mudjacking and other common concrete repair methods.

NV Waterproofing & Foundation Repair has the expertise and equipment to quickly raise and level many types of slab-on-grade concrete, so you can use those areas around your home without worry.

If you have a driveway that's sunken or uneven, replacing it might not be the most cost-effective option. We can use PolyLevel to raise the concrete, creating an even surface and preventing further sinking and cracking. Our driveway leveling process can eliminate unsafe conditions and improve the curb appeal of your home. The life of your driveway will also be extended for years without the need for replacement.
An uneven sidewalk not only looks bad, but it creates a tripping hazard. If the concrete slab is still intact, don't waste your money on replacing the concrete. With PolyLevel, we can raise your sunken sidewalk, allowing you to walk on the sidewalk within an hour. Our sidewalk leveling process saves you time and money.
You shouldn't have to worry about tripping on uneven concrete when relaxing on your patio. You might also notice your table and chairs wobbling because of uneven concrete. Concrete leveling can eliminate these issues and provide a safe, even surface.
If your home has sloped floors, cracks in floor tiles, gaps below baseboards, gaps at the tops of walls or sticking doors, you might have a concrete settlement problem. Our use of polyurethane foam for concrete floor leveling is a long-lasting alternative to self-leveling treatments.

Before PolyLevel, there were two basic options for lifting and leveling concrete: mudjacking and slab replacement. Both approaches have limitations and disadvantages. PolyLevel offers many advantages over traditional concrete leveling methods:
| PolyLevel Foam Injection |
Mudjacking or Slabjacking | |
| Cure Time | 15 minutes | 24 hours or more |
| Material Weight | 2 lbs per cubic foot | 100 lbs per cubic foot |
| Hole Size | 5/8" (size of a penny) | 1" (size of a quarter) |
| Waterproof | Yes | No |
Replacing a concrete slab is both expensive and disruptive. Concrete slabs can take days - or even weeks - to cure. Pouring new concrete over bad soil often delays future problems and leaves unsightly patchwork. PolyLevel material is lightweight, so it won't add weight to weak soil. Best of all, PolyLevel allows for use of concrete within hours, not weeks.
If your concrete is structurally-sound, why replace it? Replacing the concrete won't fix the soil problem that's causing the settlement. Concrete leveling is the answer.
