What Is Commercial Concrete Leveling?
Commercial concrete leveling is the process of raising sunken or uneven concrete slabs back toward their original position without tearing out and replacing the concrete. It can be applied to correct settled warehouse floors, sidewalks, parking areas, loading docks and other commercial or municipal concrete surfaces.
Polyurethane concrete leveling lifts sunken slabs by injecting expanding material under the concrete instead of demolishing and repouring the existing slab. The process can also fill underlying voids and restore support beneath the repaired area.
For commercial owners, property managers and public agencies, concrete leveling can be a less disruptive alternative to full replacement if the existing slab is still in repairable condition.

Why Commercial Concrete Sinks and What It Costs You
Commercial concrete sinks when the soil beneath a slab no longer provides consistent support. Poorly compacted fill soils can settle, runoff or leaking lines can wash away soil, freeze-thaw cycles can move the ground, and repeated forklift or truck traffic can compress the grade in [Target Location].
These conditions can create trip hazards and safety concerns, accessibility problems and standing water, while also preventing dock doors from sealing properly.

Commercial Concrete Leveling Solutions
For lifting and stabilizing sunken concrete
PolyLevel® Polyurethane Injection
PolyLevel works by injecting expanding polyurethane foam through small holes in the slab to fill voids, lift settled concrete and help stabilize the soils below. The lightweight material supports controlled lifting with minimal disruption, making it well suited for commercial and municipal concrete repair.

For sealing cracks and joints against water infiltration
NexusPro® Joint Sealant
Where open cracks or joints are present, water can travel to the soils beneath the slab and add to future settlement. NexusPro® is a flexible, long-lasting sealant used to close these openings and help protect the surrounding concrete and soils below.

How Commercial Concrete Leveling Works
Instead of tearing out and replacing sunken concrete, PolyLevel lifts the existing slab in place, helping reduce costs, downtime and disruption.
1. Inject the polyurethane material
Small injection holes are drilled through the concrete, and a two-part polyurethane material is pumped beneath the settled slab.
2. Lift and stabilize the slab
The polyurethane expands under the concrete, filling voids and generating controlled pressure that raises the slab toward the desired position.
3. Put the area back in service
The polyurethane cures fast, allowing the repaired concrete to support full loads in as little as 30 minutes after injection.
