How Much Does Mudjacking Cost? (2026 Guide)

How Much Does Mudjacking Cost?

Mudjacking typically costs $3 to $8 per square foot, with most homeowners paying $500 to $1,800 for standard residential projects.

Small repairs like a single sidewalk panel may cost as little as $200, while larger jobs like foundations can reach $2,500 or more. Compared to full concrete replacement, which often costs $4,000 to $12,000, mudjacking is one of the most cost-effective ways to fix sunken concrete.

• Driveway mudjacking: $600 to $1,200
• Sidewalk or patio repair: $300 to $700
• Foundation mudjacking: $800 to $2,500

Most contractors also charge a minimum service fee of $200 to $300, so very small jobs often fall within that range regardless of square footage.

Mudjacking Cost by Project Type

Costs vary based on project size, slab condition, and accessibility. The table below reflects typical residential pricing.

Most contractors charge a minimum of $200 to $300 per visit, regardless of project size. Small single-panel repairs often hit the minimum instead of the per-square-foot rate.

Driveway Mudjacking Cost

Mudjacking a driveway usually costs $500 to $1,500, depending on how many slabs have settled and how severe the drop is.

Most jobs involve lifting two or three panels rather than the entire driveway. If the whole slab has settled evenly, that often points to a larger soil or drainage issue, and mudjacking alone may not be a long-term solution.

Sidewalk Mudjacking Cost

Sidewalk repairs typically cost $200 to $500 per panel. These are among the most common mudjacking jobs because uneven slabs create tripping hazards.

Many cities require homeowners to maintain adjacent sidewalks, and some offer shared-cost or subsidized repair programs.

Patio Mudjacking Cost

Repairing a patio generally costs $400 to $1,200. Settlement is often caused by poor initial compaction, water runoff, or root growth.

If the patio slopes toward your home, drainage should be corrected along with lifting to prevent future settling.

Garage Floor Mudjacking Cost

Garage floor lifting costs $500 to $1,400 for most homes. Settlement typically occurs at edges or corners where water intrusion is more common.

Because garage floors support vehicle weight, patching quality matters. Poor patching can crack or show under coatings.

Foundation Mudjacking Cost

Foundation mudjacking typically costs $800 to $2,500, with larger or more complex jobs reaching $3,000 to $8,000+.

Unlike flatwork, foundation lifting is priced based on precision and injection points rather than square footage.

It is commonly used to:

• Lift settled slab foundations
• Fill voids from erosion or soil shrinkage
• Stabilize foundations before further repairs

It does not repair structural cracks or damage, which may require separate work.

Mudjacking vs. Polyurethane Foam Lifting

Mudjacking and polyurethane foam lifting, also called polyjacking or foam jacking, both raise sunken concrete slabs, but they use different materials and have different costs and performance.

When Mudjacking Is the Better Choice

Mudjacking is usually the best option for large areas like driveways and patios where cost is the main concern. It’s widely available, proven, and significantly cheaper per square foot.

The tradeoff is weight. The slurry adds load to the soil, which can lead to future settling if underlying issues are not fixed.

When Foam Lifting Is Better

Foam lifting is typically better for foundations, interior slabs, or areas requiring precision. It’s lighter, cures quickly, and uses smaller holes, but typically costs two to three times more.

What Factors Affect Mudjacking Cost?

Several factors can move your price higher or lower, even for projects that look similar at first glance.

Size of the Sunken Area

The size of the sunken area is the biggest factor in cost. Bigger areas need more slurry, more drill holes, and more labor. Most contractors charge by the square foot, but small repairs can end up costing more per square foot because of minimum job charges.

Severity and Depth of Settlement

A slab that has settled just 1 inch needs less material to lift than one that has dropped 3 or 4 inches. Deeper gaps under the slab mean more slurry is needed, which raises the cost. Slabs that have settled a lot are also more likely to crack during lifting, so a contractor should check for this before starting.

Number of Drill Holes

Contractors drill holes every 4 to 6 feet over the sunken area. More holes give better access for the slurry and allow for more precise lifting, but they also mean more patching afterward. Complex shapes or large areas with several sunken spots need more holes, which increases labor time and cost.

Slab Condition

Mudjacking is best for slabs that are still structurally sound. Concrete that is badly cracked, crumbling, or heavily worn is not a good candidate. A contractor will check the slab’s condition before giving a quote. If there is major damage, the slab may need to be partly or fully replaced instead of lifted, which is a different type of project.

Soil and Drainage Conditions

If poor drainage or erosion caused the slab to settle, these problems should be fixed before or during mudjacking. If not, the slab may sink again in a few years. Fixing drainage or adding French drains costs extra, but it is often needed to make the repair last.

Access Difficulty

Slabs that are easy to reach, like flat driveways or open patios, are the least expensive to repair. If the area is hard to access, near landscaping, or requires moving equipment through gates or around obstacles, it will take more time and cost more.

Regional Labor Rates

Mudjacking labor rates can vary a lot depending on where you live. Contractors in big cities or expensive areas usually charge more than those in smaller towns. Always get at least three quotes, since prices for the same job can vary by 30% to 50% between contractors.

How Does Mudjacking Work?

Mudjacking lifts concrete by filling the void underneath it.

1. Drilling. The contractor drills holes through the concrete slab, typically 1 to 2 inches in diameter, spaced every 4 to 6 feet across the sunken area.
2. Pumping. A slurry mixture, usually made of Portland cement, soil, and water, is pumped through the holes under pressure. The slurry fills the gaps under the slab and starts to lift it.
3. Lifting. As the slurry fills the gap and pressure increases, the slab rises. The contractor watches the process closely to avoid lifting the slab too much, which could make it uneven or stress it.
4. Patching. After the slab is at the right height, the drill holes are filled and patched with cement. The patches are usually visible but not very noticeable.

Most jobs take 2 to 4 hours, with curing time of 24 to 72 hours before full use.

Why Do Concrete Slabs Sink?

Concrete settles when the soil beneath it loses support. Common causes include:

• Poor compaction during installation
• Water erosion or drainage issues
• Freeze-thaw cycles
• Tree roots
• Plumbing leaks

Fixing the underlying cause is key to preventing future sinking.

When Mudjacking Makes Sense

Mudjacking is a strong option when the slab is intact and the problem is simply voids or soil movement underneath.

It works best when:

• The slab is structurally sound
• Settlement is localized
• The cause can be corrected

It is not ideal when:

• Concrete is cracked or deteriorating
• Settlement is ongoing or severe
• Structural foundation issues are present

DIY vs. Hiring a Pro

Mudjacking is not a DIY project. It requires specialized equipment and experience to avoid uneven lifting or cracking.

Homeowners can:

• Identify problem areas
• Get multiple quotes
• Fix drainage issues beforehand

But the lifting itself should always be handled by a professional.
