It costs more than mudjacking — here's when that's worth it. [Call (504) 517-8336](tel:+15045178336) [Get a free estimate](#estimate) Last updated: September 24, 2026 [New Orleans Concrete Leveling](https://concretelevelingneworleans.com/) connects property owners with independent local contractors for foam jacking in New Orleans — also called polyjacking or polyurethane concrete lifting. A two-part polyurethane is injected under a sunken slab, expands to fill the void, and lifts the concrete back to grade. [HomeGuide](https://homeguide.com/costs/mudjacking-cost) puts it at **$8–$25 per square foot**, roughly double mudjacking, with holes about **5/8 inch** wide and a cure time of about **15 minutes**. We don't sell one method. Foam is the better choice for some slabs and the more expensive choice for others. This page explains how it works and where it fits, so you can judge a quote that recommends it. ## What happens on the first visit When a contractor recommends foam, the estimate should explain: 1. **Why foam and not slurry** for this slab — soil, access, timing or finish. 2. **Which foam density** will be used and what it's rated for. 3. **Where the holes go** and how they'll be patched. 4. **Whether soil stabilization** is planned under the lift. 5. **The written price**, including patching and joint sealing. ## Where foam earns its price in New Orleans **Soft, compressible soil.** Foam weighs a few pounds per cubic foot; cement slurry weighs roughly a hundred. Across drained-marsh neighborhoods where the [City of New Orleans](https://ready.nola.gov/hazard-mitigation/hazards/subsidence/) says organic soils keep compacting, adding less weight under the slab is a real advantage. **Same-day use.** A driveway, garage floor or storefront walk lifted with foam can usually take traffic the same day. **Finished surfaces.** Holes about 5/8 inch wide are easier to hide on stamped, stained or coated concrete, and on interior floors. **Wet areas.** Cured foam doesn't wash out, which suits pool decks and slabs near downspouts. ## Where foam isn't worth it On a firm, well-drained base with one large open void — a common driveway or sidewalk case — **[mudjacking](https://concretelevelingneworleans.com/mudjacking/)** often does the same job for about half the price per square foot. On a slab that's shattered or crumbling, neither method helps; that's a replacement.

About $8–$25 per square foot based on HomeGuide's mudjacking cost data, with a typical contractor minimum of $300–$700. That's roughly twice the per-foot cost of mudjacking. ### How long does polyurethane foam leveling last? HomeGuide gives mudjacking five to ten years or longer and describes cured foam as waterproof and erosion-resistant, with no fixed figure. Longevity mostly depends on the soil below and whether drainage problems are fixed. ### Is foam jacking better than mudjacking? Not always. Foam is lighter, faster to cure and uses smaller holes, which suits soft soil and finished surfaces. Mudjacking costs less and works well on firm ground with large voids. ### Can you drive on it right away? Usually, yes. Foam cures in about 15 minutes, so most driveways and garage floors can take a car the same day. ### Who does the work, and are they licensed and insured? New Orleans Concrete Leveling is a free service that connects you with an independent local contractor. We ask every contractor we work with to carry a license and insurance — and we recommend confirming both before work begins. Louisiana requires a state license for residential jobs over $75,000 and home improvement registration from $7,500 to $75,000, so most leveling jobs fall below both — which makes insurance the check that matters.
