What Is Commercial Concrete Leveling?
Commercial concrete leveling is a repair method that lifts sunken, uneven concrete slabs back toward their original elevation without removing and repouring the existing concrete. It can be used to correct uneven warehouse floors, walkways, parking areas, loading docks and other commercial or municipal concrete surfaces.
Polyurethane concrete leveling raises settled slabs by placing expanding material beneath the concrete instead of removing and replacing the existing slab. The process can also fill underlying voids and restore support beneath the repaired area.
For businesses, facility managers and public agencies, concrete leveling can offer a less disruptive alternative to replacement when the existing slab is still in repairable condition.

Why Commercial Concrete Sinks and What It Costs You
Commercial concrete sinks when the soils under a slab can no longer offer consistent support. Loosely compacted fill can settle, drainage or leaking lines can wash out soil, freeze-thaw cycles can shift the ground, and years of forklift and truck traffic can compress the grade in [Target Location].
These conditions can create trip hazards and safety concerns, accessibility concerns and pooling water, while also preventing dock doors from sealing properly.

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

For sealing cracks and joints against water intrusion
NexusPro® Joint Sealant
Where open cracks or joints are present, water can reach the soils under the slab and contribute to future settlement. NexusPro® is a flexible and durable sealant used to seal these openings and help protect the surrounding concrete and soils below.

How Commercial Concrete Leveling Works
Instead of removing and replacing sunken concrete, PolyLevel raises the existing slab in place, helping cut costs, downtime and disruption.
1. Inject the polyurethane
A series of small holes is 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. Return the area to service
The polyurethane cures quickly, which allows the repaired concrete to support full loads in as little as 30 minutes after injection.
