Sunken concrete is a common problem for homeowners across Louisiana, especially in areas with shifting soil, heavy rainfall, and humidity. The good news is that you don’t always have to replace your concrete.
Polyurethane foam concrete lifting is a modern solution that raises and stabilizes sunken slabs quickly and efficiently. Instead of tearing out and replacing driveways, sidewalks, patios, or pool decks, professionals inject expanding foam beneath the slab to lift it back into place.
Companies like Hy Tech Concrete Lifting specialize in this process across South Louisiana, helping homeowners restore uneven concrete safely and affordably.
Why Concrete Sinks in Louisiana
Concrete slabs often sink because of soil movement underneath them. Louisiana soils are especially prone to shifting due to moisture changes.
Common causes include:
• Soil erosion from heavy rain
• Poor soil compaction during construction
• Expansive clay soils
• Plumbing leaks underground
• Tree root movement
When the soil supporting concrete weakens or washes away, the slab loses support and begins to sink or tilt.
According to the American Concrete Institute, soil settlement is one of the most common causes of concrete slab movement.

If ignored, these issues can create trip hazards, drainage problems, and structural damage.
What Is Polyurethane Foam Concrete Lifting?
Polyurethane foam concrete lifting is a repair method where a special expanding foam is injected beneath sunken concrete slabs.
Once injected, the foam expands and fills empty spaces beneath the slab. As it expands, it gently lifts the concrete back to its original position.
The foam then hardens, creating a stable base that helps prevent future sinking.
This process is often called:
• Foam concrete leveling
• Polyjacking
• Polyurethane slab lifting
Step-by-Step: How the Foam Lifting Process Works
1. Small Injection Holes Are Drilled
Technicians drill small holes in the concrete slab, typically about the size of a dime.
2. Polyurethane Foam Is Injected
High-density foam is injected beneath the slab through the holes.
3. The Foam Expands
The foam expands and fills voids in the soil, lifting the slab as it grows.
4. Concrete Is Leveled
Technicians carefully monitor the lifting process to bring the slab back to the correct height.
5. Holes Are Sealed
The injection holes are patched, leaving minimal visible repair marks.
Most projects are completed within a few hours, and the concrete can usually be used the same day.
Why Polyurethane Foam Works So Well
Polyurethane foam lifting has become one of the most popular concrete repair methods because it offers several advantages.
Lightweight but strong
The foam is lightweight and won’t add additional pressure to weak soils.
Water resistant
The material does not absorb water, which is important in Louisiana’s wet climate.
Quick curing
Foam cures rapidly, allowing surfaces to be used again the same day.
Minimal disruption
Only small holes are drilled, so landscaping and surrounding structures remain intact.
The U.S. Department of Transportation has even approved polyurethane foam for stabilizing roadways and bridges because of its durability.

Common Areas Where Concrete Lifting Is Used
Polyurethane foam lifting can repair many types of sunken concrete around a home or business.
Common repairs include:
• Driveways
• Sidewalks
• Pool decks
• Garage floors
• Patios
• Steps and walkways
• Concrete porches
In many cases, lifting the concrete costs much less than replacing the slab entirely.
Why Louisiana Homes Often Need Concrete Leveling
Homes in Southeast Louisiana face unique soil challenges. Heavy rain, humidity, and clay-rich soil can cause constant expansion and contraction beneath concrete slabs.
Cities such as:
• Covington
• Slidell
• Mandeville
• Hammond
• Baton Rouge
• New Orleans
frequently experience these shifting soil conditions.
This is why professional concrete leveling services are increasingly common throughout the region.
When You Should Repair Sunken Concrete
If you notice any of the following signs, your concrete may need lifting:
• Uneven sidewalks
• Cracked or tilted driveways
• Water pooling near foundations
• Trip hazards around your property
• Gaps under concrete slabs
Addressing the problem early prevents further damage and helps maintain property value.

Frequently Asked Questions About Polyurethane Foam Concrete Lifting
How long does polyurethane foam lifting last?
When installed properly, polyurethane foam concrete lifting can last many years or even decades, especially when soil conditions are stabilized.
Is foam lifting better than mudjacking?
In many cases, yes. Polyurethane foam is lighter, cures faster, and is more resistant to water than traditional mudjacking materials.
Can all sunken concrete be lifted?
Most concrete slabs can be lifted, but severely broken or structurally damaged slabs may still require replacement.
How long does concrete lifting take?
Most projects are completed within 1–3 hours, depending on the size of the repair area.
Is polyurethane foam safe for the environment?
Modern polyurethane foam used for concrete lifting is non-toxic and environmentally safe once cured.
Final Thoughts
Sunken concrete doesn’t always mean you need expensive replacement. Modern polyurethane foam concrete lifting allows homeowners to restore uneven slabs quickly, safely, and affordably.
For many Louisiana properties, this method provides a long-lasting solution to shifting soils and sinking concrete.
If you notice uneven concrete around your home, addressing it early can prevent more serious damage and restore the safety and appearance of your property.
