Concrete Leveling: PolyLevel® Polyurethane Foam Concrete Lifting

Before replacing uneven concrete, find out whether lifting is an option instead. PolyLevel® raises settled driveways, sidewalks, patios, garage floors and other concrete slabs without the expense, mess or downtime of replacement.

How Does Concrete Leveling Work?

Concrete leveling is the process of gently lifting a sunken concrete slab back to its original elevation by filling the voids beneath it. In most situations, the slab itself is still structurally sound—the real issue is that shifting soil, erosion or poor drainage has created voids underneath. Across FL, freeze-thaw cycles, heavy rainfall, shifting soils and changing moisture levels are frequent causes of settled concrete. Once the soil beneath a slab moves or erodes away, the concrete loses support and begins to sink.

Compared with traditional mudjacking, PolyLevel® polyurethane foam concrete leveling restores support without placing 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.

What Makes PolyLevel® Different

Not every concrete lifting method delivers the same long-term results. PolyLevel® was built specifically to lift and support load-bearing concrete slabs, whether that’s a driveway, sidewalk, patio or garage floor. Its lightweight, closed-cell polyurethane foam won’t absorb water or wash out, and it’s installed through small 5/8-inch injection ports that leave a cleaner finish than conventional mudjacking.

For homeowners throughout Tampa Bay, Orlando, Miami and Largo, long-term 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—and he result is 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 supporting sunken concrete slabs

    PolyLevel®

    PolyLevel® is our proprietary polyurethane foam concrete lifting system, engineered to lift and stabilize sunken concrete with precision. Injected below the slab, the foam expands to fill hidden voids, lifts the slab back toward its original position and cures quickly so most surfaces can be used normally the same day.

    • Lightweight material adds virtually no weight to the supporting soil
    • Lifts and stabilizes driveways, sidewalks, patios, garage floors and other concrete surfaces
    • Won’t wash away, shrink or deteriorate like traditional mudjacking materials
    • Installed through small 5/8-inch injection ports, keeping repairs cleaner with minimal patching
    • No costly tear-out or unsightly patchwork common with concrete replacement
    • Quick-curing formula allows most concrete surfaces to be used the same day
    • Waterproof formula won’t absorb water or break down over time
    • Environmentally friendly, inert material won’t leach into the surrounding soil
    • When paired with NexusPro®, helps reduce soil erosion and future settlement
    • Backed by an industry-leading transferable warranty

  • For sealing joints and protecting your concrete repair

    NexusPro®

    Once your concrete has been lifted with PolyLevel®, sealing open joints and cracks helps protect the repair from future water intrusion. NexusPro® is our professional-grade polyurethane joint sealant that helps keep water from eroding the supporting soil beneath your concrete, reducing the chance of future settlement.

    • Seals up expansion joints and cracks after concrete leveling
    • Helps prevent water from washing away the soil supporting your concrete
    • Helps reduce soil erosion and protect the PolyLevel® repair
    • Flexible polyurethane moves with seasonal expansion and contraction
    • UV resistant to help guard against cracking and deterioration
    • Resists both water and deicing salts
    • Backed by an industry-leading, transferable warranty
How It Works

The PolyLevel® Lifting Process

Step 1

Start with a Free Inspection

Your Design Specialist evaluates the entire concrete surface, maps out low areas, measures elevation changes and determines whether PolyLevel® is the right solution. You’ll leave with a written repair recommendation and estimate before any work begins.

Step 2

Prep the Slab

Our crew lays out strategic injection points and drills small 5/8-inch holes through the concrete—about the size of a penny. We also cover nearby landscaping, walkways and surrounding surfaces before lifting begins.

Step 3

Lift the Slab

PolyLevel® polyurethane foam is injected beneath the concrete, where it expands to fill the hidden voids beneath the slab before gently raising the concrete back toward its original position.

Step 4

Fine-Tune the Elevation

As the work progresses, our crew measures the slab’s elevation using specialized leveling equipment. Additional foam is injected as needed to achieve a smooth, even surface with precise results.

Step 5

Patch & Seal

Once leveling is complete, the injection holes get patched, and expansion joints can be sealed with NexusPro® to help keep water from eroding the supporting soil. Most concrete is ready for foot traffic in about 15 minutes and vehicle traffic within an hour.

When Does Concrete Leveling Make Sense?

Most uneven concrete doesn’t need replacing at all. If the slab is structurally sound and the issue is caused by settling soil or erosion beneath it, PolyLevel® can restore the concrete at a fraction of the cost and disruption of replacement.

If your slab has extensive structural damage—including severe cracking, widespread spalling or a compromised base—replacement may be the better long-term solution. At your free inspection, your LRE Foundation Repair Design Specialist will let you know whether concrete leveling or replacement is the best option for your property in Tampa Bay, Orlando, Miami and Largo.

Frequently Asked Questions

Why does concrete sink? 2026-10-05T15:06:35-05:00

Concrete usually sinks because the soil beneath it changes—not because the concrete itself wears out. Throughout FL, heavy rainfall, poor drainage, soil erosion, freeze-thaw cycles and seasonal moisture changes can open up empty spaces beneath concrete slabs. PolyLevel® fills those voids and brings back support without replacing the concrete. 

Can you level concrete instead of replacing it? 2026-10-05T15:06:08-05:00

In most cases, yes. If the concrete is structurally sound and the problem stems from settling soil rather than extensive damage, PolyLevel® can lift and stabilize the slab without demolition. During your free inspection, your LRE Foundation Repair Design Specialist will determine whether concrete leveling or replacement is the best long-term solution. 

Is concrete leveling a permanent fix? 2026-10-05T15:04:57-05:00

Concrete leveling is engineered to provide a long-lasting repair. PolyLevel® is a waterproof, inert polyurethane foam that resists washing away, shrinking and breaking down over time. It’s engineered to permanently fill the voids beneath concrete slabs and is backed by an industry-leading transferable warranty. 

Can PolyLevel® repair cracked concrete? 2026-10-05T15:01:26-05:00

It comes down to what’s causing the crack. If uneven settlement caused the slab to crack, PolyLevel® can lift and stabilize the concrete before the crack is sealed with NexusPro®. Hairline or cosmetic cracks that have nothing to do with settlement may only need sealing. At your free inspection, we’ll recommend the right repair for your concrete. 

Is PolyLevel® better than mudjacking? 2026-10-05T15:00:39-05:00

For most homes across FL, yes. PolyLevel® uses a lightweight polyurethane foam that won’t put unnecessary weight on the supporting soil or absorb water like traditional mudjacking materials. It’s installed through small 5/8-inch holes, provides precise lifting and is designed to deliver longer-lasting performance in areas with shifting soils and seasonal weather. 

How long does concrete leveling take to complete? 2026-10-05T14:49:20-05:00

Most residential concrete leveling projects take only a few hours, though larger repairs can sometimes take up to a day. Once the last PolyLevel® injection is complete, the concrete is typically ready for foot traffic in about 15 minutes and vehicle traffic within an hour—far sooner than the days new concrete needs to cure. 

What does concrete leveling cost? 2026-10-05T14:48:20-05:00

The cost of concrete leveling depends on the size of the slab, how far it has settled, accessibility and whether additional repairs like NexusPro® joint sealing are recommended. In many cases, PolyLevel® comes in 30–50% below concrete replacement while delivering long-lasting results backed by a transferable warranty. Schedule a free inspection to get a written estimate.
