How Does Concrete Leveling Work?
Concrete leveling is the process of lifting a sunken concrete slab back to its original elevation by filling the voids beneath it. In most cases, the concrete is still structurally sound on its own—the actual problem is that shifting soil, erosion or poor drainage has opened up voids underneath. Throughout SD, freeze-thaw cycles, heavy rainfall, shifting soils and changing moisture levels are frequent causes of settled concrete. When soil beneath the slab shifts or washes out, the concrete is left unsupported and begins to sink.
Compared with traditional mudjacking, PolyLevel® polyurethane foam concrete leveling restores support without adding significant weight beneath the slab. The expanding foam fills hidden voids, lifts the concrete with precision and helps stabilize it for long-lasting performance.
How PolyLevel® Is Different
Not all concrete leveling methods deliver the same long-term results. PolyLevel® was engineered specifically to lift and support load-bearing concrete slabs, from driveways and sidewalks to patios and garage floors. Its lightweight, closed-cell polyurethane foam won’t soak up water or wash away, and it’s installed through small 5/8-inch injection ports that make for a cleaner finish than traditional mudjacking.
For homeowners across [Target Location], lasting performance matters just as much as lifting concrete. When PolyLevel® is paired with NexusPro® joint sealant, joints are sealed against water intrusion to help limit future soil washout—creating a complete concrete repair system that protects your investment long after the slab has been leveled.
Our Complete Concrete Leveling & Protection System
For lifting and stabilizing settled concrete slabs
PolyLevel®
PolyLevel® is our proprietary polyurethane foam concrete leveling system, engineered to precisely lift and stabilize settled concrete. Injected beneath the slab, the expanding foam works into hidden voids, raises the slab back toward its proper position and cures fast so most surfaces are ready for normal use the same day.
For sealing concrete joints and protecting the repair
NexusPro®
Once the concrete has been lifted with PolyLevel®, sealing open joints and cracks helps protect the repair against future water intrusion. NexusPro® is our professional-grade polyurethane sealant for joints that helps keep water from carrying away the supporting soil beneath your concrete, reducing the chance of future settlement.

When Is Concrete Leveling the Right Choice?
Most uneven concrete doesn’t need to be replaced. If the slab is structurally sound and the problem is caused by settling soil or erosion beneath it, PolyLevel® can bring the concrete back at a fraction of the cost and disruption of replacement.
If the concrete has extensive structural damage—such as severe cracking, widespread spalling or a compromised base—replacement may be the better long-term solution.
