Poly leveling, also called polyurethane foam lifting, typically costs $600-$2,500 for a residential concrete repair, with many projects averaging about $1,200. The final price depends on the slab’s size and settlement, how much foam is needed, access for drilling and equipment, and local labor rates.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Small walkway or step | $300 | $650 | $1,200 | Limited lifting, often under 100 sq ft |
| Patio or garage slab | $600 | $1,400 | $3,000 | Price varies with voids and slab movement |
| Driveway section | $800 | $1,800 | $4,000 | One or more panels; full driveways cost more |
| Typical per-area rate | $5 per sq ft | $12 per sq ft | $25 per sq ft | Estimate based on treated area, not always the full slab |
Poly leveling prices for common concrete slabs
Contractors commonly charge about $5-$25 per square foot of treated surface. Some instead price by the job, the number of injection locations, or the amount of foam required. Because a few injection points may stabilize a large slab, multiplying the full slab area by a per-square-foot rate is a rough budgeting method, not a guaranteed quote.
A small walkway repair may start around $300-$600 when the slab is accessible and needs only a modest lift. Raising a sunken patio or a few garage panels often falls between $800 and $2,000. More extensive driveway work, multiple settled sections, or deep voids can push the total to $2,500-$4,000 or more.
A practical planning figure is about $1,200 for a straightforward residential repair. That estimate assumes standard polyurethane foam, ordinary site access, moderate settlement, and no major drainage correction or concrete replacement. Rates are often higher in high-cost metro areas and lower in less expensive markets.
Poly leveling fills voids beneath existing concrete and lifts or stabilizes the slab through small drilled holes. The quoted scope usually covers the contractor’s crew, foam, injection equipment, and basic cleanup. It does not necessarily cover sealing joints, correcting a water source, repairing damaged edges, or replacing concrete that has cracked beyond practical repair.
Assumptions: U.S. residential pricing, standard two-part polyurethane foam, normal access, and a localized repair rather than a full slab replacement.
What the foam, labor, and drilling add to a quote
Most estimates combine materials and labor into a project price, so line-item amounts may be approximate. Foam use is affected by the size of the void, the slab’s weight, and how far it must rise. Labor includes assessing the settlement, drilling injection holes, lifting in controlled stages, and patching the holes after the slab is stable.
| Quote component | Typical price | What changes the charge | Common billing basis |
|---|---|---|---|
| Polyurethane foam | $2-$8 per sq ft of treated area | Void volume, foam density, and lift height | Material allowance or included |
| Labor | $75-$150 per crew hour | Number of injection points and setup time | Hourly or bundled into job total |
| Drilling and injection setup | $100-$400 | Hard access, thick concrete, and hole count | Per project |
| Hole patching and cleanup | $50-$250 | Number and size of drilled holes | Included or added line item |
| Travel or minimum charge | $100-$350 | Distance and small-job scheduling | Per visit or project |
Labor pricing can be hard to compare because a contractor may quote a flat rate that includes equipment, travel, and materials rather than separate hourly charges. For reference, a two-person crew working 3-5 hours at an effective $75-$150 per crew hour represents roughly $450-$1,500 in labor value, before foam and other project costs.
Ask whether the bid includes foam, mobilization, hole patching, and cleanup before comparing totals. A quote that appears cheaper may exclude work that another contractor has included.
How slab size and lift height change the foam bill
The surface area helps estimate the scale of a job, but slab dimensions alone do not determine foam use. A contractor must fill gaps below the slab and apply enough upward pressure to raise it without overcorrecting. A small slab with a deep void can use more material than a larger slab that has settled only slightly.
Lift height is one important threshold. A slab needing less than about 1 inch of correction may require less foam and fewer adjustments than one needing 2-3 inches. Raising a slab several inches, especially where soil has washed away, may require staged injection, more foam, or a separate plan to address the underlying soil.
Concrete thickness and panel size also matter. A 4-inch sidewalk panel is generally lighter than a 6-inch driveway slab or a thick garage floor, but the contractor still has to account for reinforcement, loading, and where the concrete bears on the ground. Large or irregular panels may need more injection points to achieve an even lift.
Access can add time and expense when equipment cannot park close to the work area, gates are narrow, or the slab is inside a building. A long hose run, landscaping obstacles, or a need to protect finished surfaces may add roughly $100-$500, depending on the site and contractor. Limited access can also make a small project subject to a minimum service charge.
Ask the estimator to identify the treated area and expected lift height, not just the slab’s total square footage. Those details make it easier to understand why two similar-looking projects have different foam allowances.
Do driveway and patio quotes vary by region?
Local labor, travel distance, contractor availability, and business overhead affect poly leveling prices. As a broad comparison, quotes in high-cost coastal cities and dense metro areas may run 10%-25% above a typical national planning estimate. Smaller towns and lower-cost regions may come in 5%-15% below it, although a limited number of specialists can reduce the savings.
Regional differences are not a reliable substitute for project details. A rural property far from the contractor’s service area may incur a trip charge even where hourly wages are lower. In a city, parking restrictions, access rules, and scheduling around traffic can increase setup time. Ask whether the quote includes travel and whether the company has a minimum charge.
Climate and drainage can affect the scope, too. Freeze-thaw movement, heavy rain, and poorly directed downspouts may contribute to repeated settlement. Poly foam can lift a slab, but it does not automatically correct the water or soil condition causing movement. A quote for a lift alone may therefore be lower than a quote that includes joint sealing, drainage adjustments, or other repairs.
Compare at least two local estimates that describe the same panels, lift target, and included work. A percentage comparison between cities is less useful if one contractor is pricing only an isolated slab and another is including adjacent sections or drainage work.
How long a residential foam lift takes
A straightforward repair covering a few panels often takes about 2-5 hours on site, including setup, injection, and cleanup. A larger driveway or a project with several separate slabs may take most of a day. The slab can often be used soon after the foam has cured, but the contractor’s instructions should determine when vehicles or heavy loads can return.
Most of the time is not simply spent pumping foam. The crew checks the slab’s elevation, drills holes, injects material in controlled amounts, and monitors the lift. Moving too quickly can raise one edge unevenly or lift a panel beyond the intended height. Hard-to-reach work, multiple elevations, or a slab that needs careful adjustment can extend the visit.
Labor time affects price most on small jobs with a service minimum. A short repair may still require a crew, specialized equipment, and a round trip, so its total will not fall proportionally with square footage. Larger jobs can have a lower effective price per treated square foot when the crew can work continuously at one site.
Confirm the expected arrival window, working time, and vehicle-use restrictions in writing. If a contractor needs additional visits or charges a separate mobilization fee, that should appear in the estimate.
Polyurethane foam versus mudjacking for settled concrete
Polyurethane foam leveling commonly costs about $5-$25 per treated square foot. Traditional mudjacking, which pumps a cement-based slurry beneath concrete, often runs about $3-$15 per square foot. Mudjacking can be less expensive for large, accessible slabs, while foam is lighter, cures quickly, and can be practical where drilling small holes and limiting added weight are priorities.
| Method | Typical installed rate | Typical project range | Price consideration |
|---|---|---|---|
| Polyurethane foam | $5-$25 per sq ft | $600-$2,500 | Material and equipment can raise the starting price |
| Mudjacking | $3-$15 per sq ft | $500-$2,000 | Often economical for larger areas with suitable access |
| Concrete replacement | $8-$20 per sq ft | $1,500-$5,000 for a small area | Demolition, hauling, forming, and new concrete are included as scope requires |
These ranges overlap because job size and local labor can outweigh the choice of method. Mudjacking adds heavier material beneath the slab, and the injection holes are often larger. Foam uses specialized material and equipment, which contributes to its higher starting price. Neither approach is suitable if the concrete is badly fractured, unstable, or no longer structurally sound.
Replacement may be the better value when a slab has extensive cracking, crumbling edges, severe unevenness, or repeated movement. A contractor can price lifting and replacement separately so the homeowner can compare the cost of correcting the current slab with the cost of removing and repouring it.
Choose based on slab condition and the source of settlement, not the lowest rate alone. Ask each bidder to explain whether the proposed method will address the actual failure and what work is excluded.
When removal, drainage, and crack repairs add charges
Basic foam lifting may not include related repair work. Sealing joints or cracks can add approximately $1-$5 per linear foot, depending on the sealant, joint condition, and preparation. Small surface patching may cost $100-$500, while extensive edge or concrete repairs can require a separate contractor or a replacement estimate.
Drainage corrections are another separate budget item. Redirecting a downspout or extending a discharge line may cost about $150-$600. More involved grading or drain installation can range from $500 to several thousand dollars, depending on length, excavation, and where water can legally be discharged. These improvements may help limit future soil washout but are not automatically part of a leveling quote.
Most poly leveling jobs do not require removing the existing slab, which is one reason they can cost less than replacement. If concrete must be cut or removed, disposal and hauling may add $2-$6 per square foot or more. Difficult access, thick reinforced concrete, or hazardous conditions can push removal prices higher.
Have the estimate separate lifting from optional sealing, drainage, and concrete repairs. That breakdown shows the price of the core work and makes it easier to prioritize problems that directly affect stability.
Three sample quotes for different slab sizes
These examples show how treated area, foam volume, labor, and access can produce different totals. They are planning examples rather than fixed market prices; contractor minimums and regional rates may change the final quote.
| Project | Scope and assumptions | Estimated total | Approximate treated-area rate |
|---|---|---|---|
| Front walkway | 60 sq ft; lift under 1 inch; 2-person crew, 3 hours | $550-$850 | $9-$14 per sq ft |
| Garage apron | 180 sq ft; 1-2 inch lift; moderate voids; 2-person crew, 4 hours | $1,200-$2,000 | $7-$11 per sq ft |
| Driveway panels | 360 sq ft; uneven settlement; multiple injection points; 2-person crew, 6 hours | $2,200-$3,800 | $6-$11 per sq ft |
The walkway example has the highest per-square-foot range because setup and travel are spread across a small repair. The driveway estimate has a larger total but may benefit from continuous work across several panels. If the driveway needs substantial void filling or has difficult access, its cost can exceed the example range.
Each example assumes that the concrete is suitable for lifting and that no major drainage correction, replacement, or structural repair is required. Ask contractors to state how many panels and injection points are included, and whether the quoted total changes if they discover larger voids during the job.
Use the examples to check whether a quote’s total and treated-area rate are plausible for its scope. They are not a substitute for an on-site assessment, especially when settlement is uneven or the cause is unclear.
How to lower the poly leveling quote without cutting corners
Start by defining the essential repair. If only one panel is creating a trip hazard or preventing a garage door from closing, ask whether that area can be stabilized without lifting every adjacent slab. A smaller scope can reduce foam use and labor, provided the remaining panels are not contributing to the problem.
Get two or three written estimates from contractors who perform concrete lifting regularly. Request the same details from each: treated area, anticipated lift, foam or method, included patching, travel or minimum charges, and warranty terms. A low bid that leaves out hole patching or mobilization may not be the lowest completed price.
Ask whether bundling nearby work changes the total. If a patio and walkway both need lifting, doing them during one visit may reduce repeated setup or travel charges. This is most useful when both areas need repair soon; adding unnecessary work just to reach a discount can increase the bill.
Address visible water sources before settlement worsens. Clearing clogged gutters, extending downspouts, or correcting a simple discharge issue may cost less than repeated leveling, although major grading or drainage work may require a separate estimate. Avoid requesting a larger lift than needed, and do not pay for premium material or an extended warranty without understanding what it covers.
The most reliable savings come from limiting the scope to necessary panels and comparing complete, equivalent quotes. For heavily cracked or unstable slabs, compare lifting with replacement rather than paying for a repair that may not last.
