What Does Concrete Leveling Involve?
Concrete leveling is the process of lifting a sunken concrete slab back to its original position by filling the empty space beneath it. Most of the time, the concrete is still structurally sound on its own—the real problem is that shifting soil, erosion or poor drainage has created voids underneath. All across TN, freeze-thaw cycles, heavy rainfall, shifting soils and changing moisture levels are among the most common causes of settled concrete. When the soil under a slab shifts or washes away, the concrete loses support 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 the hidden voids, lifts the concrete with precision and helps stabilize it for long-lasting performance.
Why PolyLevel® Is Different
Not all concrete lifting methods deliver the same long-term results. PolyLevel® was engineered specifically to lift and support load-bearing concrete slabs, from driveways and walkways to patios and garage floors. Its lightweight, closed-cell polyurethane foam won’t take on water or wash away, and it’s installed through small 5/8-inch injection ports that leave a cleaner finish than traditional mudjacking.
For homeowners in Nashville, long-term performance matters just as much as lifting concrete. When PolyLevel® is paired with NexusPro® joint sealant, open joints are sealed against water intrusion to help reduce future soil washout—creating a full concrete repair system that protects your investment long after the slab has been leveled.
Our Concrete Leveling & Protection System
For lifting and supporting sunken concrete slabs
PolyLevel®
PolyLevel® is our proprietary polyurethane foam concrete lifting system, engineered to precisely lift and stabilize settled concrete. Injected beneath the slab, the foam expands to fill hidden voids, brings the slab back toward its proper position and cures quickly so most surfaces are ready for normal use the same day.
For sealing concrete joints and safeguarding your repair
NexusPro®
Once your 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 stop water from washing away the supporting soil beneath your concrete, cutting down the risk of future settlement.

Inside the PolyLevel® Lifting Process
When Does Concrete Leveling Make Sense?
Most uneven concrete doesn’t need to be replaced. If the slab is structurally sound and settling soil or erosion beneath it is the cause, PolyLevel® can restore the concrete for a fraction of the cost and disruption of replacement.
If your concrete has extensive structural damage—like severe cracking, widespread spalling or a compromised base—replacement may be the better long-term solution. During your free inspection, your The Foundation Specialists Design Specialist will determine whether concrete leveling or replacement is the right option for your property in Nashville.
