Concrete leveling restores sunken, uneven, or settled concrete slabs to their original position without full replacement. The average concrete leveling project in 2026 costs between $3 and $25 per square foot depending on the method used, with mudjacking averaging $3 to $8 per square foot and polyurethane foam injection running $5 to $25 per square foot. Over 80% of sunken concrete slabs can be successfully leveled rather than replaced, saving property owners 50% to 70% compared to full slab removal and repour.
Metal America Concrete connects property owners with licensed concrete leveling contractors in all 50 states. Our network includes specialists in both traditional mudjacking and modern polyurethane foam lifting for driveways, sidewalks, garage floors, pool decks, patios, and commercial warehouse floors. Every leveling project starts with a free assessment to determine the cause of settlement and the best repair method for your specific situation.

Mudjacking vs. Polyurethane Foam Lifting in 2026
Mudjacking pumps a sand, cement, and water slurry beneath the sunken slab through 1 to 2 inch diameter holes drilled at strategic points. The slurry fills voids and raises the slab back to grade. Mudjacking costs $3 to $8 per square foot and works well for most residential leveling projects. The material adds significant weight beneath the slab, which provides stability but can contribute to future settling if soil conditions are poor.
Polyurethane foam injection uses high-density expanding foam pumped through 5/8 inch holes to lift and stabilize sunken concrete. Foam injection costs $5 to $25 per square foot but offers advantages over mudjacking including lighter material weight (roughly 2 to 4 pounds per cubic foot versus 100+ pounds for mudjacking slurry), faster cure time (15 minutes versus 24 to 48 hours), smaller drill holes, and waterproof material that will not wash away or break down over time. For commercial applications and areas with poor soil conditions, polyurethane foam is the preferred method.
Signs Your Concrete Needs Leveling
Uneven concrete creates tripping hazards, directs water toward foundations, and causes premature wear on garage door seals and thresholds. The most common signs that concrete needs leveling include visible gaps between slab sections of 1/4 inch or more, water pooling against the foundation after rain, rocking or wobbling when you step on a slab section, and visible cracks along settlement lines where one section has dropped relative to another.
Concrete settlement happens when the soil beneath the slab compresses, washes away, or was not properly compacted during original construction. According to the American Society of Civil Engineers, poor soil compaction is the leading cause of concrete settlement in residential construction. Other causes include water erosion from poor drainage, tree root decay that creates voids, and natural soil consolidation over time. Identifying and addressing the root cause is critical before leveling because lifting a slab without fixing the underlying problem leads to repeat settlement.
What Concrete Leveling Cannot Fix
Concrete leveling is not appropriate for every situation. Slabs that are severely cracked into multiple pieces, structurally compromised by rebar corrosion, or have settled more than 4 to 6 inches typically need full replacement rather than leveling. Concrete that has deteriorated from freeze-thaw spalling, salt damage, or surface erosion cannot be leveled because the problem is in the slab itself rather than the soil beneath it.
A qualified concrete leveling contractor will inspect your slab and provide an honest assessment of whether leveling is viable. If the slab needs replacement instead of leveling, the same contractor can often handle the removal, soil stabilization, and repour as a complete project. Metal America Concrete matches you with contractors who evaluate every option and recommend the most cost-effective, long-lasting solution for your specific concrete problem.
How Long Concrete Leveling Lasts
Properly performed concrete leveling lasts 8 to 15 years or longer when the underlying soil issue is addressed during the repair. Polyurethane foam leveling tends to last longer than mudjacking because the foam material is waterproof, lightweight, and does not break down over time. Mudjacking slurry can erode if water continues to flow beneath the slab, potentially leading to repeat settlement in 5 to 10 years if drainage issues are not corrected.
The longevity of any concrete leveling project depends on three factors. First, identifying and correcting the cause of settlement, whether it is poor drainage, soil erosion, or inadequate compaction. Second, choosing the right leveling method for the specific soil conditions and slab type. Third, hiring a contractor who understands soil mechanics and does not simply pump material beneath the slab without addressing the void pattern and drainage. Metal America Concrete contractors evaluate all three factors before beginning any leveling project.
