If you’re dealing with uneven or sunken concrete, one of the first questions you’re probably asking is: “How much is this going to cost?” At Sealtite Insulation & Slabjacking, we know that price is a big factor—but we also know it’s important to weigh cost against value, quality, and long-term performance.
Let’s break down what you can expect to pay for polyurethane foam concrete lifting (what we call slabjacking) here in Central Illinois, and what goes into those costs.
💵 Average Cost of Concrete Lifting in Central IL
In Central Illinois, the average cost for residential polyurethane foam concrete lifting ranges from:
$8 to $15 per square foot
(or roughly $500 to $2,500+ per project)
This can vary depending on a few key factors:
📊 What Affects the Price of Concrete Lifting?
1. Size of the Area
A small sidewalk section may cost just a few hundred dollars, while larger patios, garage floors, or driveways will cost more.
Example: Lifting a small sidewalk might cost around $400–$800, while a driveway could be $1,200–$2,500+.
2. Extent of the Settlement
Deeper or more uneven settling requires more foam, which increases the material and labor cost.
3. Accessibility
If the area is hard to reach—like behind landscaping or under a structure—it might take longer to complete, increasing labor time.
4. Void Fill & Stabilization
Sometimes it’s not just about lifting, but also filling empty spaces beneath the slab. This may require extra foam to ensure the surface doesn’t settle again.
5. Residential vs. Commercial
Larger commercial jobs often benefit from volume pricing, but may require heavier-duty foam (and more equipment), which can also affect price.
🆚 How Does This Compare to Mudjacking or Replacement?
| Service | Cost Range | Lifespan | Notes |
|---|---|---|---|
| Polyurethane Foam | $8–$15/sq ft | 10–20+ years | Light, long-lasting, fast cure |
| Mudjacking | $5–$9/sq ft | 2–5 years (avg.) | Heavy, can resettle |
| Concrete Replacement | $10–$25/sq ft | 20–30+ years | Most expensive and disruptive |
While mudjacking is slightly cheaper up front, it tends to fail sooner due to its weight and water-based composition. Concrete replacement, on the other hand, is much more expensive and time-consuming, often requiring demolition, disposal, and curing time.
