Mudjacking Cost and 2026 Ranges

Mudjacking costs $500 to $1,500 per slab section in 2026, or $3 to $6 per square foot of concrete raised. A settled driveway section costs $600 to $1,200 to level. A settled patio section runs $400 to $800. A settled sidewalk section costs $300 to $600. Mudjacking is 50% to 70% cheaper than tearing out and replacing the settled slab. This guide covers mudjacking pricing, how the process works, and when to choose mudjacking vs foam jacking vs replacement.

How Mudjacking Works

Mudjacking (also called slab jacking or pressure grouting) raises settled concrete by pumping a cement-based slurry through holes drilled in the slab. The slurry fills the void under the slab and hydraulically lifts it back to the desired level. The drill holes are then patched with concrete.

The mudjacking slurry is a mixture of water, Portland cement, sand, and sometimes limestone or clay. It is pumped under controlled pressure through 1 to 2 inch diameter holes spaced 3 to 6 feet apart across the settled area. The crew monitors the slab level in real time using a laser level or string line.

The process takes 1 to 3 hours for a typical residential section. The slab can be walked on immediately after the work is complete. Light vehicle traffic is safe after 24 to 48 hours. The injected slurry cures to approximately 1,000 to 1,500 PSI within 3 to 7 days.

Mudjacking Cost by Project Type

Driveway mudjacking costs $600 to $1,500 per settled section. Driveways are the most common mudjacking application because driveway slabs are heavy and settlement is highly visible. A two-car driveway with 2 to 3 settled sections costs $1,200 to $3,500 for mudjacking vs $4,000 to $8,000 for tear-out and replacement.

Patio mudjacking costs $400 to $1,000 per settled section. Patio slabs are thinner than driveways, requiring less material to fill the void. Patios also tend to have smaller settled areas because they carry less load.

Sidewalk mudjacking costs $300 to $600 per settled section. Sidewalk sections are relatively small (typically 4 to 5 feet wide by 5 feet long), keeping the material volume and cost per section low.

Garage floor mudjacking costs $800 to $2,000 because garage slabs are thicker (5 to 6 inches) and the settlement area is often larger. Access through the garage door limits the size of equipment that can be used, potentially increasing labor time.

Mudjacking vs Foam Jacking Cost

Mudjacking costs $3 to $6 per square foot. Foam jacking (polyurethane injection) costs $5 to $10 per square foot. Foam jacking costs 40% to 70% more than mudjacking for the same project. The cost difference reflects the higher material cost of polyurethane foam and the specialized equipment required.

Foam jacking has advantages that may justify the premium. The foam is lightweight (2 to 4 pounds per cubic foot vs 100+ pounds for mudjacking slurry), which puts less additional load on the soil. The foam cures in 15 minutes vs 3 to 7 days for mudjacking. The foam is waterproof and does not erode, while mudjacking slurry can wash out over time in high-water-table areas.

Mudjacking has its own advantages. The slurry costs less, provides more mass for stability under heavy loads, and has a 40+ year track record. For most residential applications on well-drained sites, mudjacking produces equivalent results at lower cost.

When Mudjacking Works and When It Does Not

Mudjacking works when the slab is structurally sound (no major cracks through the full thickness), when settlement is between 1/2 inch and 4 inches, and when the underlying soil issue has stabilized or been corrected. Settlement caused by a one-time event (plumbing leak, construction disturbance) is a good candidate because the cause has been addressed.

Mudjacking does not work on slabs with extensive structural cracking. The hydraulic pressure of the slurry can split a badly cracked slab further apart. Mudjacking also provides only temporary results if the underlying soil continues to settle (active clay shrinkage, ongoing erosion, or unresolved drainage issues).

Slabs that have settled more than 4 inches may be difficult to raise evenly with mudjacking. The large void volume requires significant material, and uneven lifting can cause new cracks. For extreme settlement, replacement is often more practical.

How Long Mudjacking Lasts

Mudjacking lasts 5 to 10 years on average when the underlying soil conditions are stable. Some mudjacked slabs remain level for 15 to 20 years. The longevity depends on soil stability, drainage conditions, and the quality of the original mudjacking work.

The primary risk of re-settlement is water. If water continues to erode or wash away soil under the slab, the mudjacking fill cannot prevent new voids from forming. Correcting drainage issues (grading, gutters, downspout extensions) before mudjacking significantly improves long-term results.

How much does mudjacking cost?

Mudjacking costs $500 to $1,500 per section or $3 to $6 per square foot in 2026. A typical residential project involving 2 to 3 settled sections costs $1,000 to $3,500. This is 50% to 70% less than replacing the settled concrete sections entirely.

Is mudjacking or foam jacking better?

Both methods produce good results. Mudjacking costs 40% to 70% less and works well for most residential applications. Foam jacking is lighter, cures faster (15 minutes vs days), and performs better in high-water-table areas. For budget-conscious projects on well-drained sites, mudjacking is the better value. For speed-critical or moisture-prone situations, foam jacking is worth the premium.

Frequently Asked Questions

How long does mudjacking take?

Mudjacking takes 1 to 3 hours for a typical residential project. The slab can be walked on immediately. Light vehicle traffic is safe within 24 to 48 hours. A complete driveway with 3 to 4 settled sections can usually be finished in a half day.

Does mudjacking fix cracks in concrete?

Mudjacking raises the slab back to level but does not repair cracks. Existing cracks should be sealed after mudjacking to prevent water infiltration. If the settlement caused the cracks, raising the slab may close some crack gaps but will not bond the concrete back together. Epoxy injection or crack sealant is needed for structural crack repair.

Can mudjacking damage my slab?

Improperly performed mudjacking can crack a slab if too much pressure is applied too quickly. An experienced mudjacking contractor monitors pressure and lift rate to prevent over-lifting and stress cracking. The 1 to 2 inch drill holes are standard and do not weaken the slab structurally. They are patched with concrete after the lift is complete.

How do I find a mudjacking contractor?

Search for concrete leveling or mudjacking contractors in your area. Get at least 3 quotes. Ask each contractor how many mudjacking projects they complete per year (look for 50+ per year as a sign of experience), what material they use, and whether they guarantee their work. Most reputable mudjacking contractors offer a 1 to 3 year warranty against re-settlement.
