Concrete leveling and slab lifting in New Orleans is the fastest, most cost-effective way to fix sunken driveways, patios, and walkways without tearing out and replacing the entire slab. In a city built on soft backswamp clay and organic marsh soils over a shallow water table, settlement and subsidence are inevitable. Your pile-supported house stays put while the concrete around it sinks away, creating trip hazards and water pooling problems. We use polyurethane foam injection and mudjacking to lift settled slabs back to grade, restoring safety and drainage in a single day, often for a fraction of the cost of replacement. Whether your Garden District patio has lifted under live oak roots, your Metairie driveway has sunk away from the foundation, or your Bywater sidewalk is buckling from shallow-rooted street trees, we have the equipment and expertise to bring it back level.

Why Concrete Leveling Matters in New Orleans: The Subsidence Problem
New Orleans sits at or below sea level on compressible soils that shift constantly. Unlike freeze-thaw damage in northern climates, the dominant failure mode here is uneven settlement caused by soil consolidation, water table fluctuation, and the weight of structures pressing into soft clay. Older homes built on wood piers or shallow foundations settle at different rates than their concrete slabs, leaving driveways and patios cracked, tilted, and unsafe. The city's 60 inches of annual rainfall, near-daily summer thunderstorms, and June-to-November hurricane season accelerate soil movement and moisture-driven subsidence. A sunken slab also disrupts drainage, pooling water against your foundation and accelerating mold growth in our humid climate.
- We lift settled concrete back to original grade without full replacement, saving time and cost.
- Correcting uneven slabs eliminates trip hazards and improves property safety and curb appeal.
- Restoring proper slope directs rainwater away from your home, protecting foundations and preventing mold.
- Leveling concrete extends the life of the slab by redistributing stress and preventing further cracking.
- The process takes hours, not weeks, allowing you to use your driveway or patio the same day.
In a city where subsidence is a fact of life, leveling concrete is preventive maintenance that keeps your property safe and functional.
Key info: New Orleans driveways and patios settle an average of 0.5 to 1.5 inches over 10 to 20 years. Catching the problem early with leveling prevents expensive replacement and foundation damage.

How We Lift and Level Your Concrete: A Fast, Proven Process
Our process begins with a site inspection to assess the extent of settlement, the condition of the slab, and soil conditions beneath. We use polyurethane foam injection or hydraulic mudjacking, depending on the job scope and substrate. Both methods pump material under the slab to fill voids, compact soil, and gently lift the concrete back to grade. The work is clean, fast, and requires minimal disruption to your yard or driveway. Most residential jobs are complete in 4 to 8 hours, with the slab ready to bear weight the same day.
- We drill small access holes through the concrete at strategic points across the sunken area.
- Polyurethane foam or mudjacking slurry is pumped beneath the slab under controlled pressure.
- The material expands and hardens, filling voids and lifting the concrete incrementally to grade.
- We monitor lift in real time using laser levels to ensure the slab reaches the correct height.
- Access holes are sealed with concrete to match the existing surface.
- The slab is ready for traffic within hours, with no curing time required.
This method is far faster and cleaner than excavation, replacement, and finishing, and it preserves the existing concrete while restoring safety and drainage.
Real example: A Kenner homeowner had a 20-by-12-foot driveway that had settled 1.25 inches away from the house foundation, creating a water trap and a 1-inch trip hazard at the street. We lifted it back to grade using polyurethane foam injection in 5 hours. Cost was roughly half of a full replacement, and the driveway was usable the same afternoon. See our concrete driveways service page for more examples.
Concrete Leveling and Slab Lifting Methods Compared
| Approach | Description | Best For |
|---|---|---|
| Polyurethane Foam Injection | Expanding foam is injected under the slab through small holes, filling voids and lifting the concrete with minimal disruption. | Residential driveways, patios, and sidewalks; clean, fast, no heavy equipment needed. |
| Hydraulic Mudjacking | A cement-and-sand slurry is pumped under the slab to fill voids and compact soil, lifting the concrete gradually. | Larger commercial slabs or areas where heavy-duty lift is needed; works well in New Orleans clay soils. |
| Slab Replacement | The old concrete is removed and a new slab is poured to spec, with proper grading and reinforcement. | Severely damaged, cracked, or spalling slabs where leveling alone will not restore safety or function. |
| Combination Approach | Leveling is performed first to restore grade and safety; resurfacing or sealing is applied to extend slab life. | Slabs that are structurally sound but settled or cracked; adds durability and protects against moisture and humidity. |
The right method depends on the slab condition, soil type, and your budget. We assess your situation on site and recommend the most cost-effective solution.
Concrete Leveling and Slab Lifting Cost in New Orleans: What to Expect
Concrete leveling and slab lifting typically starts at $4 per square foot, though the final cost depends on several factors unique to your property and the New Orleans environment. Settlement depth, slab size, soil condition, and access all influence the price. A small patio or ribbon driveway may cost $400 to $800, while a large settled foundation pad or commercial lot can run $3,000 to $8,000 or more. Polyurethane foam injection is generally faster and cleaner, so it may cost slightly more per square foot than mudjacking, but the trade-off is speed and minimal cleanup. Travel is included in our pricing for all of New Orleans and surrounding areas like Metairie, Kenner, and Gretna, so there are no surprise mileage fees.
The best way to understand your cost is to request a free, no-obligation estimate. We inspect the slab, measure the area, and assess soil conditions before giving you a firm quote. Most homeowners get 2 to 3 estimates to compare, and we encourage that approach. For a detailed breakdown of pricing and examples, visit our pricing overview page.

What to Look for When Hiring a Concrete Leveling Contractor Near Me in New Orleans
Finding a reliable contractor for concrete leveling and slab lifting is essential, especially in New Orleans where soil conditions are unpredictable and the work must be done right the first time. Start by asking for proof of general liability and workers compensation insurance. Get at least two or three estimates from different contractors so you can compare methods, materials, and pricing. Check references from past customers in your neighborhood, particularly those who have had work done in similar soil and weather conditions. Ask about any local permitting requirements for your specific job, especially if your property is in a historic district or subject to HOA restrictions. Finally, make sure the contractor you choose explains the process clearly, answers your questions without pressure, and stands behind their work with a warranty.
