How Much Does Concrete Leveling or Mudjacking Cost?

This article was updated using automation technology and thoroughly reviewed for accuracy by HomeAdvisor Editor Ryan Noonan.

Is uneven concrete around your home creating tripping hazards or affecting your property's appearance? The average cost to level or mudjack concrete is $1,229, with most homeowners spending between $662 and $1,866. Depending on the size and condition of the area needing leveling, costs can be as low as $325 or as high as $3,700.

Mudjacking Cost Per Square Foot

Mudjacking costs between $3 and $6 per square foot, making it an affordable option that's 25% to 50% less than replacing the slab. This process involves pumping a slurry of water, cement, and dirt beneath a sunken concrete slab to lift it back into place. When properly done, mudjacking lasts from eight to 10 years, especially if the surface doesn't need to support a constant heavy load.

Common surfaces that can benefit from mudjacking include:

• Driveways

• Patios

• Pool decks

• Porches

• Steps

• Walkways

Other Slabjacking Costs

While mudjacking is a popular method for leveling concrete surfaces, other options include foam jacking and sandjacking. Each method varies in cost and application. Foam jacking, though more expensive, provides the longest-lasting solution, whereas sandjacking offers a cost-effective alternative.

Polyurethane Foam Concrete Raising Cost

Foam jacking, also known as polyjacking, costs between $5 and $25 per square foot. This method involves injecting polyurethane foam under the concrete, and it's often used for light load-bearing surfaces. The primary cost variable is the specific material composition, as companies may use proprietary formulas.

Polyjacking:

• Lasts longer than mudjacking

• Cures in as little as 30 minutes, offering convenience for homeowners

• Provides 6,000 to 14,000 lbs. per sq. ft. of support

• Ideal for load-bearing surfaces like basements, garage floors, and foundations that support load-bearing walls

Sandjacking Cost

Sandjacking costs between $3 and $8 per square foot. This method involves lifting the concrete slab with jacks and machinery and then filling the void underneath with dry sand or dry limestone. When properly compacted, sandjacking can last longer than mudjacking.

Slabjacking Costs by Surface Type

Exterior Concrete Surfaces

Driveway Leveling

The cost per square foot is the same as a foundation, but you can level a driveway by mudjacking since it doesn't need to bear a constant load. The most common cause of a sinking driveway is downspouts pouring water next to the slab when it rains.

• A partial driveway of 200 square feet costs $650–$1,300 to mudjack and $1,500–$3,200 to foam jack.

• A full driveway of 450 square feet costs $1,500–$3,000 to mudjack and $3,200–$7,500 to foam jack.

Sidewalk Jacking

Sidewalks include both the concrete sidewalk along the street and any pathways around your home. Along the street, you might need to get a permit before doing any work. Either way, these are smaller and easier to do than most other mudjacking projects.

For sidewalks with an area of 100 square feet, you can expect the following costs:

• Mudjacking: $320–$650

• Foam jacking or polyjacking: $650–$2,700

• Sidewalk repairs cost: $750–$2,400

• Sidewalk replacements cost: $1,300–$2,600

Patio Slab Leveling

Leveling a patio slab costs about the same per square foot as you would pay for a sidewalk. It's a good idea to keep it level to avoid a tripping hazard. Plus, if you want to cover your concrete with tile or other flooring, you'll want it leveled first.

Concrete Stair Leveling

Concrete stairs often require drilling around the sides or drilling exceedingly long holes through the stairs themselves because they are thick. However, the stair area makes them fairly inexpensive to level.

Foam jacking the stairs costs $450–$950, with some jobs costing more due to the weight of the stairs.

Structural Surfaces

Foundation Jacking

You can use foam or mud to lift a foundation. Since this is a structural, load-bearing part of your home, it requires professional installation to avoid damaging the structure. The most important benefit of foundation jacking is to correct uneven concrete and add structural support. These issues can be serious, requiring prompt action.

• Mudjacking a foundation costs between $3–$6 per sq. ft., meaning a 1,500-square-foot foundation costs $4,800–$9,000 to level.

• Foam jacking ranges from $6–$25 per sq. ft., or $9,000–$39,000 for a 1,500-square-foot foundation.

Garage Floor Leveling

Garage floor mud jacking may only need a small section or the entire structure, which will change costs. Identifying the cause of the sinking before you proceed is vital, since it may require additional work first. For example, deep erosion on the side of the garage may require a structural repair with piers instead of mudjacking.

• You can mudjack a single section of a garage floor for about $550–$1,100 if the rest of the floor is in good shape.

• Otherwise, the cost of mudjacking an entire 2-car garage ranges from $1,250–$2,700.

• Foam jacking the floor would cost roughly double mudjacking.

• Adding an epoxy garage floor coat costs $1,650–$3,500 more.

Cost to Level Concrete Floor

Leveling a concrete floor in your home using mudjacking costs between $650 and $4,300, depending on several factors. Material costs are often the biggest variable, followed by the length and terms of any warranties offered. The specific leveling technique also significantly affects the price. Additionally, labor charges from local foundation repair contractors can vary based on your location.

Self-Leveling Concrete Cost

Self-leveling concrete costs between $1 and $5 per square foot (excluding labor), making it a cost-effective alternative for minor leveling issues. However, it's only suitable if the slab hasn't sunk more than an inch and isn't recommended for basement floors, regardless of the sinking degree. Before opting for self-leveling concrete, ensure it's appropriate for your specific situation.

DIY vs. Hiring a Concrete Lifting Pro

If you're experienced with concrete work, you might be able to handle small concrete lifting projects up to four square feet. However, larger slabs require the expertise of a professional mudjacking pro near you who has mudjacking machinery. Due to the high density of concrete and the need for specialized equipment to prevent cracking, hiring a pro ensures the job is done safely and effectively.
