Concrete Lifting
Restore Sunken Concrete Without Removal or Replacement
Sunken or uneven concrete is usually caused by soil movement beneath the slab—not because the concrete itself failed. When soil erodes, settles, or washes out, concrete loses support and begins to sink, tilt, or separate. Left uncorrected, this can lead to trip hazards, drainage problems, cracked slabs, and costly replacement.
Poly Lift USA provides a fast, effective solution to lift and level settled concrete using high-density polyurethane foam. Our process raises sunken slabs, fills hidden voids, and restores stable support—without tearing out concrete or disrupting your property. Most concrete lifting projects are completed in just a few hours and cost 50–75% less than full replacement.
Concrete lifting is commonly used to correct uneven slabs, eliminate trip hazards, and restore proper drainage across residential, commercial, and industrial properties.
What Is Concrete Lifting?
Concrete lifting is the process of raising sunken or uneven concrete slabs back to their proper position by injecting expanding polyurethane foam beneath the surface.
Instead of removing the slab or excavating soil, small access holes are drilled through the concrete. Polyurethane foam is injected underneath, where it expands to fill voids, stabilize the soil, and gently lift the slab into place.
This approach restores the function and safety of existing concrete while addressing the real cause of settlement—loss of support beneath the slab.
Common Signs You Need Concrete Lifting
You may need concrete lifting if you notice:
- Uneven or sunken concrete slabs
- Raised edges or trip hazards
- Cracks forming near slab joints
- Water pooling where concrete has settled
- Slabs that tilt or slope toward structures
- Gaps forming under steps, sidewalks, or driveways
- Hollow sounds when concrete is tapped
These are clear indicators the concrete has lost support below the surface.

Why Concrete Slabs Sink
Concrete doesn’t usually sink on its own—the soil beneath it changes. Common causes include:
- Soil erosion from rain, runoff, or plumbing leaks
- Poor soil compaction during construction
- Expansive soils that swell and shrink with moisture
- Downspouts and drainage directing water under slabs
- Organic material breaking down beneath the concrete
- Utility trenches or disturbed soil near slabs
When soil weakens or shifts, concrete loses uniform support and settlement begins.
Problems Concrete Lifting Helps Fix
Concrete lifting helps resolve and prevent:
- Trip hazards and uneven walking surfaces
- Pooling water and drainage issues
- Slab separation and cracking
- Vehicle and equipment instability
- Accessibility concerns
- Ongoing settlement
- Costly concrete replacement
Lifting restores both safety and function without unnecessary demolition.
Our Fix: Fast, Clean Concrete Lifting with Poly Foam
Poly Lift USA lifts concrete using expanding polyurethane foam—a clean, precise alternative to mudjacking and concrete replacement. The foam fills voids, stabilizes weak soil, and raises slabs evenly with minimal disruption.
This process allows homeowners and property managers to restore sunken concrete without excavation, heavy equipment, or long cure times.
Poly Lift USA is trusted across Florida, Georgia, Texas, Tennessee, and Alabama for dependable concrete lifting solutions. Our experience with soil conditions, erosion, and settlement patterns allows us to lift a wide range of concrete structures safely and efficiently.
How Concrete Lifting Works
Our concrete lifting process is simple and effective:
- Small 5/8-inch holes are drilled in targeted areas of the slab
- Injection ports are installed
- High-density polyurethane foam is injected beneath the concrete
- The foam expands to fill voids, stabilize soil, and lift the slab
- The slab is carefully adjusted to the proper height
- Ports are removed and holes are cleaned and patched
In most cases, concrete is ready for normal use the same day.

Polyurethane foam lifting works on most concrete structures.
Concrete Lifting FAQs
Concrete driveways rest on subgrade, which is a fancy term for the earth below. When the subgrade begins to weaken and settle, the driveway loses its support. This can be caused by a variety of factors…weather, rain, leaks, excess weight to name a few. While the root causes may vary, the end result is always the same. Structural damage.
Over time, often in months, driveway slabs begin to stress, then crack and, eventually, break apart and sink. This leads to trip hazards, unsightly appearance and a reduction in property values. This damage is structural – not cosmetic. Neither patching nor a new surface will solve the problem.
At Poly Lift USA we offer customers an environmentally safe, affordable, long-term resolution.
Our Foamjection technology has enabled thousands of property owners in Florida, Georgia, Texas and Alabama to repair their damaged driveway and save thousands in replacement costs. Our typical repair is well under 50% less than cost of replacement.
Here’s how Foamjection technology works:
- Penny size holes are drilled through the damaged slab at 5-foot intervals.
- Specially formulated polyurethane foam is pumped through the slab reaching the subgrade underneath.
- The liquid foam fills voids and expands rapidly to compact the earth beneath the slab.
- As the foam hardens it locks the slab in place. We call this stabilization.
- When lift is required, additional foam is pumped using carefully calibrated pressure gauges until the slab is raised to the desired height.
- Drill holes are filled with sanded concrete.
All Poly Lift USA repairs come with a 10-year, transferable warranty.
