How PolyLevel® Concrete Lifting Works

The causes of uneven concrete are the same for most walkways, driveways and slabs. As soil underneath a concrete slab shrinks, settles or washes away, this leaves empty space (or voids). Because the soil is no longer supporting the slab, this causes the concrete to sink.

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 mud jacking and other common concrete repair methods.

PolyLevel Step 1

Step 1: Small 5/8" holes are strategically drilled in the slab.

PolyLevel Step 2

Step 2: Injection ports are installed.

Poly Level Step 3

Step 3: Polyurethane foam is injected beneath the concrete to fill voids and raise the slab.

PolyLevel Step 4

Step 4: Holes and control joints are sealed.

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.
