What Is Concrete Leveling?

Concrete leveling is when professionals lift and level sinking concrete slabs, patios, driveways, or sidewalks using expanding polyurethane foam. This is called polyjacking, and it’s non-toxic, fast, and stronger than other concrete leveling solutions, such as mudjacking. 

Why Does Concrete Settle?

There are many reasons why concrete settles, including poor drainage, poor compaction, poor site conditions, and tree roots. The most common reason we see concrete settling is when water from gutters and rain washes dirt out from under your sidewalk or driveway. This creates pockets or voids underneath your concrete and allows it to settle. 
 
Another factor is clay-rich soil that expands and retracts according to moisture content.
This clay-rich soil expands when it’s saturated with water and shrinks when it dries out. The change in the moisture content creates unstable soil, which causes the concrete to move and sink.

What Is The Process Of Polyjacking Concrete Leveling?

Step 1: Dime-sized holes are drilled in the affected concrete.
Step 2: Polyurethane foam is injected underneath the slab.
Step 3: The foam will expand beneath the concrete, lifting the slab.

Benefits of Polyjacking

Fast Acting

15 minutes after injection, your concrete slab is ready to walk on or support vehicular traffic.

Minimally-Invasive

Polyjacking does not require any excavation.

Lightweight

The lightweight foam does not contribute to future soil settlement, unlike the heavy material used in mudjacking.

Environmentally Friendly

Polyurethane foam is inert and won't react with soil or moisture; it won't leach harmful chemicals into the ground.

Cost-Effective

Save up to 50% compared with traditional concrete slab replacement.

Waterproof

Once cured, the polyurethane material will not wash away.
