Polyjacking typically costs $1,000-$3,000 for a residential concrete-lifting job, with larger or more complex projects reaching $5,000 or more. The total depends on slab area, how far it must be raised, access for the crew, and local labor rates; small-job minimums can make per-square-foot prices misleading.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Residential polyjacking project | $500 | $2,000 | $5,000+ | Small repair through multi-slab work |
| Concrete lifting rate | $5/sq ft | $12/sq ft | $25/sq ft | Varies with lift height and access |
| Single walkway or step repair | $500 | $900 | $1,500 | Often subject to a minimum charge |
| Driveway section | $1,000 | $2,500 | $5,000+ | Depends on area and number of slabs |
Polyjacking prices for a typical driveway or slab
For a standard residential job, expect about $1,000-$3,000 to lift one or several settled concrete sections. A small porch, walkway, or garage-floor repair may cost $500-$1,500, while a broad driveway or multiple areas can run $2,500-$5,000 or more. These estimates assume sound concrete that can be lifted rather than replaced.
A common planning figure is roughly $12 per square foot, but contractors may use minimum job charges instead of a simple area rate. Polyurethane foam is injected through small holes to fill voids and raise the slab. The contractor’s quote should state which slabs are included and whether sealing injection holes is part of the price.
Assumptions: Typical U.S. residential labor rates, standard polyurethane foam, normal access, and no major drainage or concrete replacement work.
What crews charge for foam, drilling, and labor
Foam and labor are the main expenses, with equipment and mobilization contributing to the total. The following ranges are approximate portions of a residential quote, not guaranteed line-item charges; many contractors bundle them.
| Quote component | Typical range | Pricing basis | What it covers |
|---|---|---|---|
| Polyurethane foam | $3-$10/sq ft | Area and injected volume | Material used to fill voids and lift concrete |
| Labor | $75-$150/hour per technician | Crew time | Drilling, injection, leveling, and cleanup |
| Equipment and mobilization | $150-$500 | Per visit or job | Pump, hoses, truck, and site setup |
| Hole patching and cleanup | $50-$250 | Per project | Filling injection holes and removing debris |
| Drainage correction | $300-$2,000+ | Separate scope | Optional grading or water-management work |
Labor is only one part of the estimate; injected foam volume and the contractor’s minimum charge can matter just as much. A rough labor calculation is . A two-person crew working 3-5 hours at combined rates of $150-$300 per hour would represent about $450-$1,500 in labor before materials and mobilization.
How slab size and lift height change the quote
Area is important, but the volume of foam needed depends on the void beneath the concrete. A 100-square-foot slab with a 1-inch lift may need less material than the same slab requiring a 3-inch correction. Slabs needing more than 2 inches of lift, or with large uneven voids, commonly move toward the upper end of the per-square-foot range.
Ask whether the quote is based on slab area, estimated foam volume, or both. Concrete thickness, cracking, soil condition, and whether the slab can be raised without damaging nearby steps or walls also affect the contractor’s approach. If the concrete is badly fractured or the underlying soil keeps shifting, lifting may not be a durable fix.
How long polyurethane concrete lifting takes
Most straightforward residential jobs take about 2-6 hours on site, often with a two- or three-person crew. A single small walkway may take less time, while a driveway with several slabs, tight equipment access, or careful height matching can take most of a day. The quote may include a trip or mobilization fee even when the injection work itself is brief.
Confirm when the repaired concrete can be used again. Polyurethane foam cures quickly, but contractors may give different guidance for vehicle traffic, especially after a large lift. Extra site preparation, moving stored items, or coordinating access can add time and may affect the price.
Polyjacking versus mudjacking for sunken concrete
Polyjacking often costs more per square foot than traditional mudjacking, which commonly falls around $3-$8 per square foot. Polyurethane foam is lightweight and requires smaller injection holes; cement-based slurry is heavier and may be a lower-cost choice where added weight is not a concern. Actual bids vary by location, slab condition, and the amount of material needed.
Compare the full repair scope rather than choosing by the material rate alone. Ask each contractor how the method handles the existing voids, whether the slab is likely to stay level, and what warranty applies. Neither method fixes a continuing drainage or soil problem by itself.
Three residential polyjacking quotes by project size
| Example job | Scope and labor | Estimated total |
|---|---|---|
| Front walkway | 50 sq ft, about 1-inch lift, 2 technicians for 2 hours | $700-$1,200 |
| Garage slab edge | 120 sq ft, about 1-2-inch lift, 2 technicians for 3-4 hours | $1,500-$2,800 |
| Driveway and front steps | 300 sq ft across several slabs, 2-3-inch correction, 3 technicians for 5-7 hours | $3,500-$6,000 |
These examples assume usable concrete and ordinary access, with no major drainage repairs. The per-square-foot equivalent falls as project size grows in some quotes because mobilization is spread across more area, but a greater lift height can offset that savings.
Regional labor rates shift polyjacking prices
Prices in high-cost metro areas and parts of the Northeast or West Coast may run about 10%-25% above a national-style estimate. Lower-cost rural markets may be 5%-15% below it, although fewer nearby contractors can increase travel or mobilization charges. Demand, local competition, and crew availability affect quotes as much as state lines do.
Compare bids from contractors serving the same local market and covering the same slabs. A low quote may exclude hole patching, cleanup, or a second trip, so check the written scope before comparing totals.
Where homeowners can trim a polyjacking estimate
Combining nearby slabs into one visit can reduce repeated mobilization charges. Clearing vehicles, planters, and stored items before the crew arrives can also avoid paid preparation time. When a small repair is below a contractor’s minimum, ask whether other settled areas can be assessed and priced together.
Keep the repair limited to necessary lifting, but do not ignore the cause of settlement. Compare at least two or three written estimates with matching scope, foam type, hole patching, and warranty terms. Avoid paying for a larger lift than needed, and ask whether grading or drainage work is essential now or can be handled separately.
