Most homeowners pay an average of $1,229 for mudjacking services, and most projects fall between $662 and $1,867.
The average mudjacking cost is around $1,229, which is significantly more affordable than pouring a new slab or using other concrete repair methods. There are many cost factors to consider to get an accurate estimate, including the size of the slab you need lifted, the type of mudjacking you use, and the condition of the concrete, all of which we’ll discuss below.
The average cost of mudjacking runs between $3 and $8 per square foot. Mudjacking is a concrete repair process that lifts sunken concrete. It involves pumping a cementitious or expanding foam substance under the slab for support.
The cost of mudjacking can vary so wildly because there are a few different factors that can push your per-square-foot price and total project price up or down quite significantly.
Most mudjacking contractors bill for projects on a per-square-foot basis, which means the larger the area you need lifted, the more you can expect to pay.
For example, if you have a 100-square-foot section of concrete patio that has cracked off from the rest and begun to sink into the ground, you’re looking at between $300 and $800 for the repair. A larger, 400-square-foot section of concrete patio costs between $1,200 and $3,200.
Your mudjacking contractor might need to drill additional holes to raise particularly large portions of concrete, which also adds to the labor cost.
| Project Square Footage | Typical Price Range |
|---|---|
| 50 | $150–$400 |
| 100 | $300–$800 |
| 150 | $450–$1,200 |
| 200 | $600–$1,600 |
| 250 | $750–$2,000 |
| 300 | $900–$2,400 |
| 350 | $1,050–$2,800 |
| 400 | $1,200–$3,200 |
The cost of mudjacking depends, in part, on the materials you want your contractor to pump under the slab to lift it back into place. Depending on the location of the concrete and the long-term durability and structural integrity the slab needs, you can choose from cement, expanding polyurethane foam, or a sand-based cementitious material.
Generally speaking, cement and the sand-based cementitious slurry will be the most affordable options, and polyurethane foam will usually have the highest price.
| Mudjacking Material | Average Cost per Square Foot |
|---|---|
| Concrete | $3–$8 |
| Polyurethane foam | $6–$25 |
| Sand-based cement | $3–$10 |
As is the case with any professional service, labor is going to be a significant portion of your mudjacking costs—usually between 50% and 70% of your total. The location of the slab you need lifted can play a role in your labor costs and determine how easy it is to work with concrete.
For example, if your mudjacking professional has easy access to the work area—as is the case with a patio, sidewalk, driveway, or pool deck—the labor costs could be lower than if they need to maneuver equipment down into a basement or crawl space and work on a foundation in cramped conditions.
Every mudjacking job will require some preparation, but the extent of that prep work can play a role in your total mudjacking project cost.
For less complicated mudjacking repairs—like for non-structural driveways, sidewalks, or patios—your concrete repair specialist might not need to do much planning, as the concrete isn’t under significant load and plays no part in your home’s stability. Significantly more planning usually goes into slabjacking or raising any concrete your home relies on for support. Additional planning could drive up your preparation costs, and you might need to consult a structural engineer first.
Similarly, if there’s any risk of utility lines running through the concrete you need to lift, your contractor will need to take some time to do a site assessment and mark out the lines before beginning. This could take additional time and also demand more planning to ensure the lines remain safe throughout the concrete lifting process.
There are a few different techniques your mudjacking specialist can use, depending on the type of concrete project they’re leveling, your soil conditions, and more.
| Slab Leveling Technique | Typical Cost per Square Foot |
|---|---|
| Mudjacking (outdoor surface) | $3–$6 |
| Sandjacking | $3–$8 |
| Slabjacking (foundation) | $3–$20 |
| Polyurethane leveling | $5–$25 |
The national average cost of a mudjacking project is $1,229, but you could pay more or less than this based on where you live. Generally, higher-cost areas will demand higher labor prices to account for the higher cost of living.
The table below includes typical mudjacking project costs across a few major cities so you can get an idea of how the average price can vary.
| City | Cost Range |
|---|---|
| Seattle, WA | $1,800 |
| New York, NY | $2,500 |
| Los Angeles, CA | $1,500 |
| Atlanta, GA | $1,230 |
| Dallas, TX | $870 |
| Tampa, FL | $1,360 |
| Kansas City, MO | $830 |
There are a few different methods your contractor can use to raise a sunken section of concrete. The price per square foot for each of these methods varies quite a lot, as does the intended use, project ease, durability, and more.
| Method | Durability | Suitable for DIY |
|---|---|---|
| Foamjacking | High | No |
| Polyurethane Jacking | High | No |
| Sandjacking | Moderate | No |
| Self-Leveling | Low | Yes |
| Slabjacking | Moderate | No |
The typical cost per square foot for foam leveling is between $3 and $25. Foam leveling involves pumping an expanding polyurethane foam through a hole in your concrete slab, which then expands and lifts the slab back into place. The term “foam leveling” can be used synonymously with the term “polyurethane jacking,” but it more often refers to using an expanding foam under non-structural slabs, like concrete patios or driveways.
“Polyjacking” or polyurethane costs around $5 to $25 per square foot. Polyjacking lasts longer than mudjacking, is lightweight, cures in just 30 minutes, and makes a great technique for repairing load-bearing surfaces such as foundation, basement, or garage floors. Since the poly foam is lightweight, there’s less of a risk of sinking in the future than with slabjacking that involves a heavy cementitious material.
Expect to pay between $3 and $8 per square foot for sandjacking. Sandjacking is made with dry limestone sand mixed with water, making a slurry that a concrete repair specialist pumps from the sides of the concrete slab without the need to drill the slab. Typically, sandjacking is best in areas where the soil is wet.
Concrete self-leveling costs anything between $1 and $5 per square foot. Self-leveling is a simpler method of concrete leveling that can only be used in a slab that is sunk less than an inch. It is not safe for basement or foundation slabs and is best for simpler (non-load-bearing) surfaces. You add the liquid slurry on top of your unlevel concrete slab, and gravity helps it settle perfectly level before it hardens.
The lifting cost for a concrete slab usually ranges from $3 to $6 per square foot or up to $17 per square foot for foundation slabs.
“Slabjacking” really just refers to any method that your contractor uses to lift a portion of your home’s foundation back into place. That can include concrete, sand-based cementitious material, or expanding foam. It adds stability and can last permanently, depending on the material they use.
Mudjacking a sinking garage floor can be completely different than mudjacking your foundation slab, mainly because some surfaces call for further support that may require different materials, more planning, and a specific leveling method to achieve.
Driveway leveling costs $600 to $1,200 with mudjacking and $1,400 to $3,000 with foamjacking, depending on the thickness of the concrete driveway.
The cost to fix a concrete sidewalk runs between $300 and $600 for mudjacking and between $800 and $1,800 for foamjacking.
The concrete leveling cost for a two-car garage ranges from $1,100 to $2,200. Mudjacking a small portion may only cost $300.
Concrete patio leveling costs between $600 and $3,200.
Leveling concrete subfloors costs $600 to $4,000.
Concrete foundation costs between $4,500 and $30,000 to mudjack, and foamjacking can range from $7,500 to $37,500.
Concrete step leveling costs between $200 and $500.
Pool deck lifting costs between $300 and $600.
DIY mudjacking is possible for small areas and costs between $1 and $5 per square foot for the concrete, plus any tools you rent. Larger or critical locations, like areas with loose soil underneath, will require professional help to avoid further cracking in the concrete slab.
Not every concrete slab is suitable for leveling or lifting, and some damaged concrete demands full replacement. We recommend you contact a concrete mudjacking professional near you to help you determine whether it's a good idea.
Mudjacking is just one foundation repair method that you can use to level your concrete, but it’s usually one of the most cost-effective options to fix foundation issues. We’ll explain some of the other options below and include some pricing for the sake of comparison. Keep in mind that these don’t all solve the issue of sunken concrete, and some are better for other related problems.
Underpinning: Underpinning involves jacking up the sunken portion of concrete and installing a permanent support underneath. This costs between $1,000 and $3,000 per pier.
Basement waterproofing: Waterproofing helps resolve foundation leaks and can involve a wide array of methods. Basement waterproofing costs between $1,000 and $10,000 in most cases.
Crack sealing: Sealing foundation cracks costs between $250 and $1,000, depending on how large the crack is and whether or not it’s structural. Structural cracks may require additional repair methods.
New concrete slab pouring: Pouring a new concrete foundation costs $4,500 to $20,000 in most cases, but prices can vary wildly, depending on square footage and the type of foundation.
Bowing foundation wall stabilization: Hydrostatic pressure from expansive soil can push foundation walls inward, demanding stabilization. The different methods for stabilizing this issue usually cost between $1,000 and $8,000.
Mudjacking can be an expensive repair, but there are a few things you can do to save money on labor and materials.
Choose the most affordable method that solves your issue. For example, if your soil can support the weight of additional concrete under a patio, opt for sandjacking or mudjacking over foamjacking. This could save you around $20 per square foot, which could add up to thousands of dollars for the whole project.
Consider DIY leveling for simple projects. If you have a garage slab that has only sunk down a half-inch, using a self-leveling concrete should suffice and could save you hundreds or thousands of dollars. The cost per square foot will be $1–$5 as opposed to up to $25 for more intensive foamjacking.
Hire a pro for structural repairs. Any concrete that supports the weight of your home should only ever involve lifting by a professional. It might be tempting to do the work yourself and save money upfront, but mistakes could lead to tens of thousands of dollars in structural damage to your home, which could end up costing you far more than you’d save in the long run. Plus, your home insurance likely won’t pay for damage caused by DIY foundation repairs.

Mudjacking often takes between one day and three days to fully dry. The larger the project area is, the more time it will take to dry. You should not walk on the concrete or place furniture or decor on the concrete until you’re sure it’s completely cured, which a pro can help determine.
Mudjacking should last for 5 to 10 years, so it’s considered a temporary solution to sinking concrete. However, there are some cases where mudjacking fails before this time period, like if you have loose soil below the concrete to begin with or a karst landscape is to blame for the sinking concrete. Some mudjacking projects can last for well beyond a decade, depending on the underlying issue.
No, mudjacking is not considered a permanent fix and typically lasts for 5 to 10 years. Mudjacking doesn’t resolve the underlying issue of loose or mobile soil, so it’s likely to return in the future. Polyurethane foamjacking solutions can last significantly longer, but the time frame for both depends on the underlying problem and whether you address that alongside your sunken concrete.
