Mudjacking or foam — when the cheaper method costs more
On a per-square-foot basis mudjacking starts lower. That is a real difference, and on a thick, well-supported slab sitting on stable ground it is often the right call.
The decision changes when the soil underneath is the problem. Slurry is heavy. Pumping weight into ground that failed because it could not carry weight is how a slab gets lifted twice. Foam weighs a fraction of that, goes in through smaller ports, and cures fast enough to use the surface the same day.
So the honest way to read the two ranges is not “$3 to $9 versus $5 to $20.” It is: what is the chance this slab needs a second visit, and what does a second visit cost? A cheap lift that settles again inside two seasons is the most expensive option on this page.
Minimum charges, and why they exist
A minimum charge of roughly $300 to $550 per visit is standard in this market. It covers mobilising equipment, hose, material and crew to a site regardless of how small the slab is. It is why one sunken step and a whole driveway do not differ in price as much as their square footage suggests, and it is a good reason to bundle the small stuff into one visit.
What drives a job to the high end
Void volume, not slab area
Two driveways of the same size can differ by thousands of dollars. Material fills space, and washout under dispersive soil creates far more space than a simple sag does. The void is the invoice.
An uncontrolled water source
If a downspout, a sprinkler head or a leaking line is still feeding the soil, the honest quote includes fixing that first. Skipping it is the cheapest bid and the worst value.
Lift height and slab condition
A quarter-inch correction and a three-inch correction are different jobs. Thin, unreinforced or already-cracked concrete needs more ports and a slower, staged lift.
Access
A back patio behind a narrow gate, an interior floor, or a pad set well off the road all take longer to reach than a driveway apron at the curb.
Leveling versus replacement
Leveling generally runs 50 to 70 percent below full replacement. It also keeps the slab you already have, which means no demolition, no disposal, no forms and no cure time before you can use the surface again.
When replacement is genuinely the right call
- The concrete is broken into many small pieces rather than a few large ones. Lifting needs a slab that behaves as a panel.
- The surface is spalled or crumbling through its depth, so it is failing as material, not as elevation.
- The slab was poured at the wrong grade in the first place. Lifting it flat still sends water toward the house.
- Repeated lifts have already been done and the underlying water source was never resolved.
We would rather tell you that than sell you a lift that will not hold.
