The slab
Start from a common job, then replace every figure with your takeoff. Changing method or access never overwrites a rate you already typed. This prices a lift — not a new pour, and not a basement waterproofing job.
Your crew rates
A $42/h operator loaded at 32% is $55.44. Quoting the raw wage on a published $4.50/sf special is how a four-inch poly backyard hang that looked fine turns into a two-day loss after the first extra hole. Zero void depth still prices — pump hours are the void, not an error.

Where the hours go
Where the cost goes
Transparent arithmetic from your own inputs. Starting hours and material rates are common ballpark figures, not an industry standard or a structural design — replace them with your own takeoff.
Hand the customer a proposal
The price above is for you. This is the page you print or save as a PDF and give to the customer — your details, their details, the scope, the deposit split, and a line for them to sign. Your business details are saved on this device so you only type them once; the customer’s details are never saved.
Everything on the printed page is text you typed or a number this calculator worked out. It contains no warranty, lien, or cancellation wording — those depend on your jurisdiction and your contract, and this tool is not the place to invent them.
Common questions
Why can a competitor advertise “$4.50 a square foot” for slab lifting?
Usually because the special is written around one specific job, and that job is a preset here: an 80 sq ft sidewalk with a 1-inch void, mudjacked, truck parked street-side. It really does price low. What the per-square-foot number cannot see is method, void depth, access, extra holes, and joint sealing. Price your actual slab beside the special and the gap becomes a list of line items you can show the homeowner instead of an argument about who is honest.
Why does polyurethane cost so much more in material than mudjacking, when it’s faster?
They trade material cost for labor and cure time. Mudjacking starts at $7.50 of slurry per cubic foot of void and 0.18 crew-hours per cubic foot. Polyurethane foam starts at $48 per cubic foot — more than six times the material — but only 0.09 crew-hours per cubic foot, roughly half the labor, and it sets in minutes instead of days. Neither number is universally cheaper; the void volume and how fast the customer needs the slab back decide which one wins on a given job.
Why does backyard or interior access add hours if the void volume is the same?
Because moving the pump and hose is not part of drilling the hole. A driveway job with the truck parked at the slab adds no access hours. A backyard job run through a hose or a gate adds 1.6 hours for the extra distance. An occupied interior floor adds 2.8 hours for containment, protection, and working around furniture and foot traffic. All three can lift the exact same void volume at very different total prices.
Is this the same as pouring a new slab, or basement waterproofing?
No. This prices lifting an existing settled slab back toward level with mudjacking or polyurethane — it is not a new-slab pour (that is cubic yards of fresh concrete) and not basement waterproofing (a French drain, a sump pit, and a discharge line). If the slab is cracked beyond repair or the settling is a foundation problem rather than a void under a walk or drive, lifting is the wrong tool and this calculator will still happily price the wrong job.
Is my data uploaded anywhere?
No account and no network requests — the calculator runs entirely in your browser. A share link encodes only the inputs you choose into the address bar and is never sent to us, and the optional usage counter records only which features were used and the day, never your slab size, wages, or prices. Only your business details for the printed proposal are kept in this browser’s local storage so you do not retype them, and the customer’s details are never saved.
What’s the difference between the bid price and the walk-away price?
The bid price already includes your target margin on top of labor, materials, and overhead. The walk-away price is the total cost underneath it — pump hours, access time, slurry or foam, extra holes, and joint sealing — the point below which the lift stops being profitable at all. Typing a price you are considering shows you the margin or the loss before you send it.
