How much does mudjacking or concrete leveling cost per square foot in New Brunswick?

Mudjacking (slabjacking) typically costs $3-$6 per square foot in New Brunswick, while polyurethane foam leveling runs $5-$10 per square foot. Most contractors have minimum charges of $800-$1,500 regardless of the area size, making small repairs relatively expensive per square foot.

Mudjacking involves pumping a cement-based slurry under the sunken slab through 1-2 inch holes drilled in the concrete. The mixture of cement, sand, and water fills voids beneath the slab and lifts it back to level. This traditional method works well for driveways, sidewalks, and garage floors that have settled due to soil erosion or poor compaction. The holes are patched with concrete after the work is complete, leaving visible repair marks that fade over time.

Polyurethane foam injection (also called poly leveling) uses expanding foam injected through much smaller holes (about 5/8 inch). The foam expands to fill voids and provides more precise lifting control. While more expensive upfront, poly leveling leaves smaller, less noticeable holes and the foam won't wash out like cement-based slurry can during New Brunswick's spring thaw and heavy rain periods.

New Brunswick's freeze-thaw cycles make concrete leveling particularly valuable because our 150+ annual freeze-thaw cycles accelerate the settlement process. Water infiltrates beneath slabs during spring thaw, then freezes and expands, creating larger voids. Sunken concrete around foundations also creates drainage problems during NB's wet springs, directing water toward basement walls instead of away from the house.

Typical NB pricing scenarios: A sunken driveway section (100 square feet) runs $800-$1,200 for mudjacking or $1,200-$1,800 for poly leveling. Leveling a garage floor approach (50 square feet) costs $800-$1,000 minimum due to setup charges. Sidewalk panel lifting (25 square feet) still hits the minimum charge, making the effective cost $30-$60 per square foot for very small areas.

When concrete leveling makes sense: Settlement of 1-3 inches where the concrete is otherwise in good condition, no major cracking, and the underlying cause (poor drainage, inadequate base) can be addressed. When replacement is better: Extensive cracking, settlement over 4 inches, or repeated settling in the same area indicates deeper soil problems that leveling won't solve permanently.

Professional assessment is essential because the success of leveling depends on identifying why the concrete settled originally. In New Brunswick's clay soils and areas with high water tables, repeated settlement often occurs unless drainage improvements accompany the leveling work.
