PolyLevel concrete leveling typically costs about $5-$25 per square foot, with many residential projects landing near $10-$15 per square foot. The final quote depends on the slab area, amount of settlement, foam volume, access, regional labor rates, and whether the contractor must seal holes or address drainage problems.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| PolyLevel price per square foot | $5 | $10-$15 | $25 | Small, simple slabs cost more per sq ft when minimum charges apply. |
| Small residential repair | $500 | $1,200 | $2,500 | Often a walkway, landing, or small patio. |
| Driveway or garage slab | $1,500 | $3,000 | $6,000 | Price varies with slab area and settlement. |
| Foam injection work | $5 per sq ft | $10-$15 per sq ft | $25 per sq ft | Contractors may price by slab, injection volume, or minimum service fee. |
What PolyLevel costs for common concrete slab sizes
For a straightforward repair, a 100-square-foot walkway or patio may cost about $700-$1,800. A 300-square-foot garage slab often falls around $1,800-$4,500, while a 600-square-foot driveway section can reach $3,000-$8,000 if several areas need lifting. These totals assume polyurethane foam injection, standard residential access, and no major concrete replacement or drainage work.
A per-square-foot price is only a starting point; project minimums and foam volume can matter more on small repairs. A contractor may charge a minimum mobilization fee even when only a few square feet need correction. Larger slabs can have a lower unit rate when the work is continuous, but extensive voids or multiple injection points can raise the total.
Quotes may cover only the portion of the slab that needs lifting, rather than the slab’s full footprint. For example, if a 400-square-foot driveway has a settled 120-square-foot corner, the estimate may be based on that repair zone and the amount of foam required. Ask whether the quote measures the whole slab or only the affected area.
Assumptions: Typical U.S. residential labor, ordinary concrete access, and standard polyurethane foam; local minimum charges and site conditions vary.
How foam, labor, drilling, and sealing shape the quote
PolyLevel estimates combine materials, injection labor, equipment use, and job setup. The foam is injected through small drilled holes to fill voids and raise the slab. Contractors may also include surface preparation, hole patching, cleanup, and a service or mobilization charge. These items are not always listed separately, so a detailed written estimate helps compare bids on the same scope.
| Quote component | Typical range | What it covers | Common price effect |
|---|---|---|---|
| Polyurethane foam | $2-$10 per sq ft of repair area | Injection material and volume used | More voids or deeper settlement require more foam. |
| Labor | $75-$150 per crew-hour | Drilling, injection, monitoring, and cleanup | Complex lifting or multiple zones take longer. |
| Equipment and setup | $100-$500 per visit | Specialized pump, hoses, transport, and mobilization | Small jobs feel this minimum most strongly. |
| Drilling and hole sealing | $3-$10 per injection hole | Small access holes and patching after injection | Hole count depends on slab layout and repair plan. |
| Removal or disposal | $0-$800 per project | Limited cleanup or removal of loose concrete | Major demolition is usually outside basic leveling. |
Confirm whether the estimate includes drilling, hole patching, cleanup, and a minimum service charge. The contractor may quote one bundled amount rather than separate line items. A low headline rate can exclude setup or additional foam, while a higher all-in quote may include those costs. Ask for the number of repair zones, approximate injection volume, and any charges that could change after work begins.
Why slab thickness, lift height, and void depth change price
Settlement is not priced by surface area alone. A 200-square-foot slab that needs a small correction over a shallow void may require less foam and labor than a 100-square-foot slab that has dropped several inches over a large unsupported area. Contractors assess where the slab has settled, whether it can be lifted safely, and how much material is likely to be needed.
The depth and distribution of the void usually affect material use more than the visible crack length. A lift of less than 1 inch may be relatively simple if the slab is intact and the soil support is consistent. Lifting 2 inches or more, or correcting several separate low spots, can require more injection points, careful staged lifting, and additional foam. Those conditions commonly push estimates toward the higher end of the range.
Slab thickness also matters. A 4-inch walkway is generally a different injection job from a 6-inch driveway or garage slab, which weighs more and may need a larger or more controlled lift. Reinforcement, joints, nearby foundations, and the risk of damaging an attached structure affect the repair plan. Concrete that is badly cracked or crumbling may not be a good candidate for lifting.
Access can change the labor portion. A clear driveway lets the crew position hoses and equipment efficiently. A backyard slab reached through a narrow gate, stairs, or a long hose run may take longer. If the crew cannot reach the area with its standard equipment, ask whether additional setup or access charges are included.
What regional labor rates and access add to PolyLevel prices
Local pricing commonly differs from a national estimate by about 10%-25%. In high-cost metro areas, labor, insurance, travel, and operating expenses can push a quote above the national midpoint. Rural customers may see lower labor rates but higher travel or mobilization charges, especially when the contractor is far from the job site. These differences are estimates, not fixed regional price rules.
Compare quotes from contractors serving the same local market, not just online per-square-foot averages. In a dense city, parking restrictions or limited equipment access may add time. In colder regions, frost-related movement and seasonal scheduling can affect when repairs are practical. In areas with expansive clay soils or frequent freeze-thaw cycles, contractors may recommend correcting drainage alongside lifting, which adds scope and cost.
Some companies have a minimum charge of roughly $500-$1,500 for a visit. This can make a small local patch seem expensive per square foot, even when the crew is on site for only a few hours. A contractor traveling a long distance may quote a separate trip fee, while a larger combined job can spread that expense across more repair area.
How long a residential foam leveling crew typically works
Many residential PolyLevel jobs take about 2-6 hours on site, including setup, drilling, injection, and cleanup. A small walkway correction may take 1-3 hours, while a driveway with several settled sections can take most of a day. The actual schedule depends on the number of injection points, foam volume, access, and how carefully the slab must be raised.
Labor time is usually shorter than a concrete replacement project, but the crew must raise the slab gradually. Fast lifting can create stress, widen cracks, or push one portion higher than another. The crew may pause to check elevation and distribute foam beneath the slab in stages. If multiple sections need different corrections, the process takes longer than a single, uniform lift.
Contractor labor rates can range from about $75-$150 per crew-hour when quoted separately, although many firms price the job as a package. Ask whether the crew’s travel, setup, and cleanup time is included. Concrete can often be used again soon after the repair, but the contractor should specify any limits on vehicle traffic, heavy loads, or use of the surface.
Three sample quotes for a walkway, garage, and driveway
The following examples show how area and job scope affect totals. They assume ordinary access, no structural concrete replacement, and typical U.S. labor. Actual quotes can fall outside these ranges if the slab has deep voids, severe cracking, drainage issues, or unusually difficult access.
| Project | Scope and rate | Labor estimate | Illustrative total |
|---|---|---|---|
| Walkway section | 80 sq ft at $9-$15 per sq ft, plus a small-job minimum | 2 workers for 2-3 hours | $700-$1,500 |
| Garage slab corner | 250 sq ft affected at $8-$16 per sq ft | 2 workers for 3-5 hours | $1,500-$3,500 |
| Driveway sections | 500 sq ft affected at $10-$20 per sq ft | 2-3 workers for 4-7 hours | $4,000-$9,000 |
These totals are planning ranges, not guaranteed bids. The walkway example includes the effect of a potential minimum charge. The garage example assumes one corner and nearby voids can be lifted without replacing concrete. The driveway example allows for multiple injection zones and more foam; a simple, shallow correction could cost less.
Which repairs and add-ons can push the estimate higher
PolyLevel raises and supports concrete, but it does not automatically solve every cause of settlement. Poor drainage, leaking downspouts, erosion, or unstable soil may continue to affect the slab. Correcting grading or extending a downspout might cost about $200-$1,500, depending on the work. French drains or more extensive drainage changes can cost several thousand dollars and are normally quoted separately.
Separate slab lifting from drainage correction, crack repair, and concrete replacement in the estimate. Crack sealing may add roughly $100-$500 for a limited residential repair, while extensive crack work varies with crack length and condition. Removing and replacing a damaged slab can add $8-$20 or more per square foot, including demolition and disposal, depending on access, thickness, reinforcement, and local concrete rates.
Removal is not always necessary when a slab is stable enough to lift. However, foam injection may not be appropriate if the concrete is badly broken, too thin, or unable to move as a unit. A contractor should explain whether the proposed repair addresses the actual problem and what signs would make replacement a better option. Avoid paying for unrelated upgrades unless the scope and expected benefit are clear.
How to lower a PolyLevel quote without shrinking the repair
Start by asking each bidder to price the same marked repair areas and identify the expected lift. Compare the number of areas, included minimum charge, hole patching, cleanup, and any drainage work. A quote based only on total square footage is difficult to compare if one contractor includes more of the slab or assumes a larger lift.
Keep the scope consistent before comparing the per-square-foot rate. Combining nearby walkway, patio, and driveway repairs into one visit may reduce repeated mobilization fees. If the work is not urgent and the slab is stable, scheduling during a less busy period may improve availability, though discounts are not guaranteed. Ask whether a weekday appointment or flexible date changes the price.
Prepare access by moving vehicles, planters, furniture, and other obstacles before the crew arrives. Clear access can reduce setup delays and may prevent extra labor charges. Share photos and measurements when requesting estimates, but do not rely on a remote quote as a final price when the contractor has not inspected settlement or slab condition.
Get at least two or three itemized estimates from contractors experienced with polyurethane concrete lifting. Ask about warranty coverage, exclusions, and whether it applies to future soil movement or only the repair work. A lower quote is not necessarily a better value if it omits necessary areas or has narrow warranty terms. Skip optional cosmetic work unless it is needed to protect the repair or restore safe use.
