When the soil beneath a concrete slab compresses or washes away, the unsupported concrete sinks, cracks, and becomes uneven. This sunken concrete creates an immediate safety hazard and indicates underlying structural instability.
At Elite Moisture Solutions, we provide a fast and durable method to fix this problem without the need to demolish and replace the existing concrete. We use a concrete leveling process that lifts and stabilizes sunken concrete slabs by injecting high-performance, expanding polyurethane foam directly underneath the surface. This closed-cell foam fills the voids in the soil, raises the slab back to its proper position, and forces existing cracks to close. As the foam expands, it seals the cracks from the underside, providing a permanent, waterproof base for your concrete.
Signs Your Concrete Needs Leveling
When the base soil fails, the heavy concrete above it shifts and breaks. If you observe the following physical issues around your property, your concrete requires professional leveling and stabilization:
Settling Slab Foundations: The primary concrete slab foundation supporting your home has sunk or cracked, causing uneven interior floors.
Sunken Driveways: The concrete panels of your driveway have settled unevenly, creating a jarring vertical drop when pulling your vehicle into the garage.
Uneven Sidewalks: Individual sections of your concrete sidewalk have shifted, creating a vertical lip and a dangerous trip hazard.
Sloping Patios: Your exterior concrete patio has sunk and now slopes incorrectly, directing rainwater toward your home instead of away from it.
Cracked Garage Floors: The concrete floor inside your garage has cracked and settled into the underlying soil.
The Advantages of Concrete Leveling Over Replacement
Completely demolishing and replacing a concrete slab is an expensive process that causes major demolition and disruption to your property. Polyurethane concrete lifting foam provides direct structural, financial, and environmental advantages over traditional replacement:
Lower Cost and Minimal Disruption: Foam leveling is available at a lower cost than pouring new concrete. The process requires smaller injection holes, making the repair less invasive, nearly invisible, and eliminating the need for major demolition.
Same-Day Use and Fast Curing: New concrete requires days to cure before it can be used. Polyurethane foam cures fast, meaning the stabilized concrete is ready for traffic in minutes, not days.
Lightweight and Strong: Pouring new, heavy concrete over weak soil often leads to further settling. The foam provides massive lifting power but is lightweight and strong, ensuring it won’t add extra weight to the soil or cause re-settling.
Waterproof Soil Stabilization: The foam is waterproof. As it expands, it fills the voids, seals cracks from the underside, and stabilizes weak soils, preventing future washouts.
Environmentally Friendly: The closed-cell foam prevents moisture infiltration and contamination without the massive waste generated by concrete demolition.
Our Concrete Leveling Process
We use a specific, step-by-step method to raise your concrete and close the cracks safely.
Step 1: Preparation: We drill small holes directly through the sunken concrete slab.
Step 2: Injection: We inject foam through the holes and into the void beneath the slab.
Step 3: Expansion and Lifting: The foam expands rapidly, creating upward pressure. The slab lifts back to its original, level position, and the open cracks in the concrete are forced closed.
Step 4: Soil Stabilization: As the foam expands, it compresses the loose soil below. It stabilizes the base, seals the underside of the closed cracks, and provides a waterproof barrier that prevents the soil from washing away again.
Cost & Financing forConcrete Leveling
The total cost of a concrete leveling project depends on the square footage of the sunken slab and the volume of polyurethane foam required to fill the voids. Leveling is significantly less expensive than a full concrete replacement.
Estimated Cost: Average cost per job ranges from $2,000 to $7,000, depending on the severity of the settlement and the size of the slab.
Flexible Financing: We make concrete leveling affordable. We offer 6-month, 12-month, and 18-month “same-as-cash” options, as well as traditional financing terms through our trusted partnerships with Regions Home Improvement Financing and Greensky.
Frequently Asked Questions About Concrete Leveling
Will the foam wash away if it rains?
: No. The closed-cell polyurethane foam is completely waterproof. It seals the area, fills the cracks from below, and stabilizes weak soils, which actively prevents future washouts beneath the concrete.
Can you level a primary foundation slab, or just sidewalks?
We use this process for both primary and secondary applications. We can lift and stabilize heavy slab foundations, as well as garages, driveways, patios, and sidewalks.
Do I need to seal the cracks on top of the concrete after leveling?
No. The expanding foam physically closes existing cracks as the concrete slab lifts back into its proper position. The closed-cell polyurethane foam is completely waterproof, which prevents moisture infiltration and seals the area from underneath.
How long does it take for the leveling foam to dry?
The polyurethane foam cures fast. The concrete slab is completely stable and ready for traffic in minutes, rather than the days required for new poured concrete to cure.
