Concrete leveling cost calculator

Lifting a sunken 240 sq ft section of driveway costs about $573 – $955 with mudjacking, or $1,045 – $1,742 with polyurethane foam. Tearing it out and pouring new runs $3,408 – $5,680. Enter your own slab below.

Lift is how far the lowest edge has dropped. Leave lift points empty to use a typical spacing for the method.

Mudjacking vs foam leveling

On the 240 sq ft driveway above, foam costs about 82% more than mudjacking ($1,394 against $764 at the midpoint). The extra buys smaller holes, about 5/8 in instead of 1.5 to 2 in, and a fill that weighs far less than cement slurry, so it adds little load to soil that already let the slab sink.

Mudjacking makes sense when the soil underneath is firm and the budget is tight. Foam is worth the premium over soft or wet ground, or where the patched holes will show, like a front walk.

When leveling beats replacement

For the same driveway, mudjacking is about 17% of the cost of replacing it and foam about 31%. Lifting wins when the slab is in one piece and has dropped as a unit: a sunken panel, a tipped walk, a patio pulling away from the house.

Replace instead when the concrete is broken into loose pieces, crumbling at the surface, or has dropped more than 4 in. Lifting a slab like that only raises the damage. The concrete slab cost calculator prices the new pour with tear-out, so you can put the two numbers side by side.

Indoor floor with dips rather than a slab that has sunk? That is poured on top, not pumped underneath: the self-leveling concrete calculator counts the bags.

Hiring concrete leveling contractors

Leveling companies usually quote after a site visit, because they need to see how far the slab has dropped and where the voids are. Ask each one which method they use, how many holes they plan to drill, whether sealing the joints afterwards is included, and what happens if the slab settles again.

A quote well above the calculator's range for your inputs is worth a question, and so is one far below it: the cheapest bids sometimes leave out joint sealing or pump too little material to hold.

Methodology. The void under the slab is taken as a wedge half as deep as the lift. Slurry or foam, drill holes, setup and joint sealing are priced line by line with BLS OEWS May 2025 cement-mason wages, then overhead and profit, with a minimum charge for small jobs. See the methodology page.
