Slabjacking · concrete leveling
Slabjacking & mudjacking cost
Lifting a settled concrete slab costs about $600–$1,800 for a typical job — a fraction of replacing the concrete. Estimate yours below, then see how mudjacking and foam compare.

Two methods, two price points
Both methods lift the slab by injecting material through small holes underneath. Mudjacking is cheaper and proven; foam is pricier but lighter, faster-curing, and more durable. Either way, leveling beats replacement on cost by a wide margin when the slab itself is still sound.
Make sure it’s a slab problem, not a foundation problem
Slabjacking is for flatwork — driveways, patios, garage and basement floors. If your house is settling (sloping floors, cracks tracking through the structure, sticking doors), that’s a foundation issue that needs piering, not slabjacking. Our guide on piering vs. slabjacking lays out which problem is which.
Frequently asked questions
How much does slabjacking cost?
A typical slabjacking or mudjacking job runs about $600–$1,800, depending on the slab size, how far it has settled, and how many injection points are needed. Small single slabs sit at the low end; large driveways or multiple sections cost more.
Mudjacking vs. polyurethane foam (polyjacking) — which is cheaper?
Traditional mudjacking pumps a cement-and-soil slurry and is usually cheaper upfront. Polyurethane foam (polyjacking) costs more but is lighter, cures in minutes, resists washout, and lasts longer. For driveways and high-traffic slabs many homeowners now choose foam despite the higher price.
Does slabjacking fix my house foundation?
No — slabjacking lifts settled flatwork: driveways, patios, garage floors, sidewalks, and basement slabs. It does not repair a settling house foundation; that needs piering or underpinning. Make sure you’re solving the right problem before you book the job.
How long does slabjacking last?
When the underlying soil is stable, both methods can last many years. Polyurethane foam generally lasts longer because it doesn’t wash out or compress. If the soil keeps eroding or settling, any lift is temporary until the soil issue is fixed.
