New Orleans Concrete Leveling connects businesses, property managers and HOAs with independent local contractors for commercial concrete leveling in New Orleans — lifting settled slabs, aprons and walks back to grade by injecting material under them. Commercial work is quoted on site because slab thickness, loads, access and downtime vary widely. As reference points, HomeGuide lists mudjacking at $4–$9 per square foot and polyurethane foam at $8–$25, and HomeGuide puts mudjacking at 30–50% less than replacement.
For a business, the bigger number is usually downtime. Replacing a loading apron or a section of warehouse floor means demolition, forms, a pour and a week or more of cure before it takes a truck. Foam leveling can often be done overnight, with traffic back on the slab the next morning.
What happens on the first visit
A commercial walkthrough covers the slab and the operation around it:
- Every uneven joint and trip edge, measured and mapped — useful for your records as well as the quote.
- Loads the slab carries: forklifts, racking, trucks, dumpsters.
- Slab thickness and condition, usually from a test hole or drawings.
- Work windows — nights, weekends or between shifts — and how traffic will be routed.
- Method and a written scope and price, often phased by area.
Where commercial slabs fail in the metro
Loading docks and aprons take the heaviest point loads and the most water. When the apron drops away from the dock, trailers ride over a lip and the joint breaks down faster. Dumpster pads sink under repeated impact loads and wash out from runoff. Warehouse floors fail at joints, where forklift wheels pound the edges and a small drop becomes a rocking slab. Storefront walks and parking lot curb areas become trip hazards for customers.
The ground makes it worse in industrial areas. NASA's radar study of the region found subsidence rates up to 2 inches a year in industrial zones such as Michoud in New Orleans East and Norco (NASA JPL).
Trip hazards and liability for property managers
A raised or sunken edge on a walk that customers or tenants use is a liability question. The 2010 ADA Standards (§303) allow a vertical change in level of up to 1/4 inch; changes between 1/4 and 1/2 inch must be beveled, and anything over 1/2 inch must be ramped. Leveling the low slab back flush removes the change entirely rather than just grinding a bevel. See trip hazard repair for walk-focused work.
Foam, slurry and soil stabilization for heavy slabs
Most commercial lifts use polyurethane foam: high-density formulations are made for heavy loads, cure in minutes, and add little weight to soft soil. Mudjacking can make sense for large voids under lightly loaded slabs. Where the soil itself is soft to depth, contractors may inject deeper first — see soil stabilization.
Ask for the product's rated compressive strength and whether the contractor will stabilize soil beneath the lifted area. The contractor hiring guide lists the questions to ask.
Scope, licensing and pricing
Commercial jobs are priced from a site walkthrough and are often phased so different areas can stay open. The reference ranges are $4–$9 per square foot for mudjacking and $8–$25 for foam, before any soil stabilization.
Louisiana requires a commercial contractor license for commercial projects where the full contract price exceeds $50,000. Larger lifts, or work bundled with joint repair and resurfacing, can cross that line. Check licensing on bigger scopes — see does a concrete leveling contractor need a license in Louisiana? — and ask for a certificate of insurance naming your company.
What a proper commercial concrete leveling job includes
- Mapped survey of uneven joints and edges
- Load and slab-thickness check before pricing
- Work scheduled around your operating hours
- Written scope, phasing and price
- High-density foam where loads demand it
- Lift monitored with a laser across joints
- Holes patched and joints sealed
- Certificate of insurance on request
DIY patch vs cheapest operator vs proper commercial concrete leveling
| Factor | DIY patch or topping | Cheapest operator | Proper leveling job |
|---|---|---|---|
| Fixes the void under the slab | No | Sometimes | Yes |
| Actually raises the slab | No | Yes | Yes |
| Drop measured at every joint first | No | No | Yes |
| Method chosen for your soil | n/a | Whatever rig they own | Yes |
| Written price before drilling | n/a | Rarely | Yes |
| Holes patched, joints sealed | n/a | Holes only | Yes |
| Drainage cause addressed | No | No | Yes |
| Carries liability insurance | n/a | Ask | Ask — and verify |
| Typical life | Cracks as the slab keeps moving | Short if the cause isn’t fixed | 5–10+ years (mudjacking) |
| Typical cost, 150 sq ft patio | Materials only | Lowest bid | $600–$1,400 slurry · ~$1,200–$3,750 foam |
Proper-job cost and life from HomeGuide's mudjacking cost data; foam range calculated at HomeGuide's $8–$25/sq ft. Resurfacers and self-leveling toppings cover the surface; they don't lift the slab.
