Mudjacking typically costs $4 to $9 per square foot, and polyurethane foam lifting $8 to $25. A 150 sq ft patio usually runs $600–$1,400, a partial driveway $800–$1,800, and a full driveway $1,800–$4,100 with mudjacking. Expect a minimum charge of $300–$700.
Foundation Repair Baton Rouge lifts sunken driveways, patios, sidewalks, pool decks and garage floors across the Capital Region. Concrete leveling is one of the few repairs where the price is genuinely predictable once the square footage is known.

What changes the price
- Size of the void. Deep voids under a panel take more material. Mudjacking slurry is cheap per yard; foam is not.
- Minimum charges. A single small panel still pays the minimum, so it costs more per square foot.
- Material choice. Foam costs more but weighs a few pounds per cubic foot versus roughly 100 for slurry, uses smaller holes, and cures in minutes.
- Joint sealing. Sealing joints after the lift adds a little cost and prevents a repeat.
- Access. Pump hoses need to reach; long runs to a back patio add time.
When replacement is the better spend
Lifting works when the panel is intact. If it’s cracked into several pieces, badly spalled, or heaved by tree roots, lifting won’t give a good surface and replacement is worth the extra cost. And if the sunken slab is part of the house foundation, not flatwork, you need pressed pilings, not mudjacking.
Making the lift last
Most flatwork in Baton Rouge sinks because water washes out the base — usually a downspout or yard runoff. After the lift, seal the joints and move the water: see foundation drainage. For the pros and cons of each material, read mudjacking vs polyurethane foam.
Bottom line
Expect $4–$9 per square foot for mudjacking and $8–$25 for foam, with a $300–$700 minimum. For a measured, per-square-foot price, call Foundation Repair Baton Rouge.
