Uneven or sinking concrete is a common problem for homeowners and business owners alike. Whether it’s a sunken driveway, an uneven sidewalk, or a sloping foundation, addressing concrete settlement issues quickly is essential to maintaining safety and curb appeal.
Concrete lifting—also known as slab jacking—is a cost-effective alternative to complete concrete replacement. But how much does concrete lifting cost? The answer depends on several factors, including the method used (polyurethane foam vs. traditional mudjacking), the size of the repair, and the overall condition of the concrete slab.
What Is Concrete Lifting?
Concrete lifting is a repair technique used to raise sunken or uneven concrete back to its original position. Instead of replacing the entire slab, small holes are drilled, and a specialized lifting material is injected underneath to fill voids and lift the slab.
There are two main methods of concrete lifting:
1. Polyurethane Foam Lifting – Uses expanding polyurethane foam to stabilize and lift concrete.
2. Mudjacking (Traditional Method) – Uses a mixture of cement, sand, and water to raise the slab.
Each method comes with its own costs, advantages, and best-use scenarios, which we’ll discuss below.
Polyurethane Foam Lifting vs. Mudjacking: Cost Comparison
The cost of concrete lifting varies based on the method chosen. Here’s a breakdown of how they compare:
1. Polyurethane Foam Lifting Cost
Polyurethane foam lifting is a modern and more durable alternative to traditional mudjacking. It involves injecting lightweight, high-density foam beneath the slab to expand and lift the concrete.
Average Cost: $5 – $25 per square foot
Typical Project Cost: $1,000 – $3,000 (depending on slab size and complexity)
Factors That Affect Polyurethane Lifting Costs
Below are the primary factors that impact the cost of polyurethane foam concrete lifting:
1. Size of the Area- One of the most significant factors in determining the cost of polyurethane foam lifting is the total square footage of the area that needs to be raised.
2. Extent of Settlement – The deeper the concrete slab has sunk, the more polyurethane foam will be required to lift and stabilize it, increasing the overall cost.
3. Foam Material Costs- Polyurethane foam is a premium material compared to the cement slurry used in traditional mudjacking, making it more expensive upfront.
4. Site Accessibility-The location of the sunken concrete slab plays a major role in the overall labor and equipment costs.
5. Climate and Soil Conditions-Since polyurethane foam works by expanding to fill voids, the underlying soil stability can influence the amount of material needed.
6. Additional Repairs and Finishing Work-While polyurethane lifting corrects the slab’s height, other repairs may be necessary for a seamless restoration, adding to the final cost.
2. Mudjacking (Traditional) Cost
Mudjacking is the traditional method of concrete lifting, involving a thick slurry of cement, sand, and water that is pumped under the slab to lift it.
- Average Cost: $3 – $8 per square foot
- Typical Project Cost: $600 – $2,500 (depending on slab size and complexity)
Factors That Affect Mudjacking Costs
1. Labor-Intensive Process-Mudjacking requires significant manual labor, making it a time-consuming process, especially for larger or heavily settled slabs.
2. Material Costs-One of the primary reasons mudjacking is more affordable than polyurethane lifting is its lower material costs.
3. Settlement Depth-The depth of settlement plays a crucial role in determining the cost of mudjacking.
4. Project Accessibility-If the area requiring mudjacking is difficult to access, additional equipment or labor may be needed.
5. Climate and Soil Conditions- Mudjacking is less effective in regions with frequent freeze-thaw cycles or unstable soil conditions.
Which Method Is More Cost-Effective?
Mudjacking is generally the cheaper option upfront, but polyurethane lifting offers better durability and a longer lifespan, potentially saving you money in the long run.
Pros and Cons of Polyurethane Foam vs. Mudjacking
Advantages of Polyurethane Foam Lifting
- Lightweight and Non-Intrusive – Doesn’t add extra weight to the soil, reducing the risk of future sinking.
- Fast Curing Time – The foam hardens in 15-30 minutes, allowing you to use the area the same day.
- Long-Lasting Results – Resists moisture and doesn’t break down over time.
- Smaller Drill Holes – Less noticeable than mudjacking, making it ideal for driveways, patios, and high-visibility areas.
Disadvantages of Polyurethane Foam Lifting
- Higher Initial Cost – More expensive than mudjacking.
- Not Ideal for All Situations – This may not work well in extreme structural failures.
Advantages of Mudjacking
- Lower Cost – A budget-friendly option for smaller projects.
- Proven Technique – Has been used for decades and is well understood.
- Good for Large Slabs – Works well for sidewalks, driveways, and foundations.
Disadvantages of Mudjacking
- Longer Curing Time – Requires 24-48 hours before the area can be used.
- Heavier Material – Can cause future settlement due to added weight.
- More Visible Repair – Larger holes (up to 2 inches) make the repair more noticeable.
What Affects the Cost of Concrete Lifting?
Several factors influence the overall cost of your concrete lifting project, including:
- Size of the Slab – Larger surfaces require more material and labor.
- Degree of Settlement – Deep voids need extra material, increasing costs.
- Site Conditions – Accessibility, soil conditions, and drainage affect pricing.
- Repair Urgency – Emergency repairs may come at a premium cost.
If you’re unsure which method is best for your situation, getting a professional assessment can help determine the most cost-effective solution.
Signs You Need Concrete Lifting
How do you know if concrete lifting is necessary? Look out for these warning signs:
- Uneven Surfaces – Slabs that tilt or sink in certain areas.
- Tripping Hazards – Raised edges or cracks that pose safety risks.
- Water Pooling – Sunken areas where water collects after rain.
- Visible Cracks – Indicating possible foundation or soil issues.
- Garage or Driveway Sinking – Creating an uneven slope or gaps.
Ignoring these signs can lead to worse structural damage and higher repair costs over time.
Is Concrete Lifting Worth the Cost?
If you’re debating whether to lift or replace your concrete lifting is almost always the better choice due to:
- Lower Costs – Repairing is significantly cheaper than replacing an entire slab.
- Faster Repairs – Most lifting jobs are completed within a few hours.
- Minimal Disruption – No need to tear out and replace concrete.
- Eco-Friendly Option – Uses fewer materials compared to full slab replacement.
For homeowners and businesses dealing with minor to moderate concrete settlement, lifting is a cost-effective and long-lasting solution.

Choosing the Right Concrete Lifting Method for Your Budget
So, how much does concrete lifting cost? The answer depends on the method you choose, the size of the project, and the extent of the damage.
For budget-conscious repairs, mudjacking is a cost-effective solution. For long-term durability, polyurethane foam lifting is the better investment.
Regardless of the method, concrete lifting is a smart alternative to costly replacement, restoring safety and functionality to your property.
