If your driveway, sidewalk or patio has sunk, the first question is usually how much it will cost to fix. The short answer: concrete leveling typically runs about $3 to $8 per square foot for mudjacking and about $5 to $25 per square foot for polyurethane foam, which works out to a few hundred dollars for a small repair and a few thousand for a large driveway. Either option usually costs well below tearing out and replacing the slab.
Those are national averages, and Denver pricing depends on your slab and your soil. This guide breaks down what concrete leveling costs per square foot, what pushes a quote up or down, and how lifting compares to replacement, so you can judge any estimate you receive.
Concrete Leveling Cost Per Square Foot
The method you choose is the biggest price driver. Here are typical ranges for the most common options:
| Method | Typical Cost Per Square Foot | Best For |
|---|---|---|
| Mudjacking (cement-based slurry) | About $3 to $8 | Large, flat slabs and tighter budgets |
| Polyurethane foam | About $5 to $25 | Weak soil, faster return to use, long-term results |
The wide foam range reflects differences in lift depth, foam density and job complexity. Prices include labor and materials, and most contractors apply a minimum charge, so very small repairs can cost more per square foot than larger ones.

What Does Concrete Leveling Cost for a Typical Project?
Here is what those per-square-foot ranges look like on common residential projects. These examples are for illustration only and are not quotes.
| Project Size | Mudjacking | Polyurethane Foam |
|---|---|---|
| 100 sq ft (small patio or walkway section) | About $300 to $800 | About $500 to $2,500 |
| 250 sq ft (sidewalk run or driveway apron) | About $750 to $2,000 | About $1,250 to $6,250 |
| 500 sq ft (larger driveway) | About $1,500 to $4,000 | About $2,500 to $12,500 |
To estimate your own project, measure the length and width of the sunken area in feet and multiply them to get square footage. Then multiply by the per-square-foot range for your method. For a more precise number, see our guide to driveway concrete leveling or request a quote.
What Affects the Cost of Lifting Concrete?
Two slabs of the same size can get very different quotes. These are the main factors:
- Method and material. Foam materials cost more than slurry, which is why foam is usually priced higher per square foot.
- Size of the area. Larger jobs cost more overall but often cost less per square foot.
- How far the slab has dropped. A deeper lift needs more material and more time.
- Size of the voids underneath. Large empty spaces take more material to fill.
- Access. Tight yards, gates and hard-to-reach slabs add labor.
- Number of slabs and joints. Lifting several panels and keeping them aligned takes more work than one.
- Underlying cause. If drainage or soil problems are behind the settling, fixing them adds to the project but protects the repair.
Concrete Lifting vs. Replacement Cost
For a slab that is still structurally sound, lifting generally costs far less than replacing it. One widely cited estimate puts mudjacking at roughly 25% to 50% less than replacement, and the gap can be larger once you count everything replacement involves:
- Demolition of the old slab
- Hauling away and disposing of the concrete
- Forming and pouring new concrete
- Curing time before you can use the surface
- Possible damage to landscaping and surrounding areas
Lifting avoids most of that. The slab stays in place, the work is usually done in a single visit, and many surfaces can be used again within a day or less.
Replacement still makes sense when the concrete is crumbling, badly cracked or structurally failed. If you are weighing both options, see our overview of the best concrete repair solutions in Colorado.
Why Denver Projects Can Cost More Than Expected
Much of the Front Range sits on expansive clay that swells when wet and shrinks as it dries, and freeze-thaw cycles add to the movement. If water keeps getting under a slab, a lift can settle again and you end up paying twice. Fixing the drainage problem first, or alongside the lift, is often the smartest money you can spend.

How to Get an Accurate Concrete Leveling Quote
A reliable quote starts with an on-site inspection. Before you hire, ask:
- Is the price per square foot or a flat project price, and what does it include?
- Which method do you recommend for my slab, and why?
- What is causing my concrete to sink, and will the repair address it?
- How long before I can walk or drive on it?
- What warranty do you offer?
Be cautious of quotes that are far below everyone else’s, quotes given without seeing the slab, and contractors who recommend the same method for every job.
Frequently Asked Questions
How much does it cost to level a concrete driveway? Most driveways fall somewhere between a few hundred dollars for a small section and several thousand dollars for a large slab, depending on the method, the size and how far the concrete has dropped.
Is concrete leveling cheaper than replacement? For structurally sound slabs, usually yes. Lifting avoids demolition, disposal and a new pour, so it generally costs significantly less.
How much does it cost to lift a sidewalk slab? Sidewalk repairs are often some of the least expensive jobs because the areas are small. A single slab can often be lifted for a few hundred dollars, though minimum charges apply. See our sidewalk leveling page for details.
Why do concrete leveling quotes vary so much? Quotes differ because of the method, the lift depth, the size of the voids, access and the cause of the settling. Comparing quotes only works if each one covers the same scope.
How long does concrete leveling last? It depends on the material and whether the cause of the settling is fixed. Addressing drainage and soil issues is what makes the repair last.
