What Is Commercial Concrete Leveling?
Commercial concrete leveling is the process of lifting settled, unlevel concrete slabs back toward their original elevation 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 raises settled slabs by placing expanding material beneath the concrete instead of removing and replacing the existing slab. The process can also close underlying voids and restore support under the repaired area.
For business owners, property managers and public agencies, concrete leveling can provide 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 soil beneath a slab can no longer provide consistent support. Poorly compacted fill can settle, drainage or leaking lines can wash out soil, freeze-thaw cycles can shift the ground, and repeated forklift or truck traffic can compress the grade in Nashville.
Those changes can create trip hazards and safety risks, 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 relies on expanding polyurethane foam injected through small holes in the slab to fill voids, lift sunken concrete and help stabilize the underlying soils. The lightweight foam allows for controlled lifting with little disruption, making it a good fit for commercial and municipal concrete repair.

For sealing cracks and joints against water infiltration
NexusPro® Joint Sealant
Where open cracks or joints exist, water can reach the soils beneath the slab and contribute to future settlement. NexusPro® is a flexible, long-lasting sealant used to close these openings and help shield the surrounding concrete and soils beneath it.

How Commercial Concrete Leveling Works
Instead of removing and replacing sunken concrete, PolyLevel raises the existing slab in place, which helps reduce costs, downtime and disruption.
1. Inject the polyurethane
Small injection holes are drilled through the concrete, and a two-part polyurethane is injected under the settled slab.
2. Raise and stabilize the slab
The polyurethane expands under the concrete, filling voids and building controlled pressure that lifts the slab toward the desired position.
3. Put the area back in service
The polyurethane cures quickly, letting the repaired concrete carry full loads in as little as 30 minutes after injection.
