MUDJACKING (SLABJACKING) — LIFT SETTLED CONCRETE

Mudjacking (slabjacking) lifts settled concrete slabs by pumping a cement-sand-water slurry through small holes drilled in the slab. The pressurized slurry fills voids beneath the slab and lifts it back to level. Mudjacking costs 50-75% less than full replacement and can be done in a few hours. Effective for driveways, sidewalks, garage floors, patios, pool decks, and stoops that have settled due to soil erosion, compaction, or washout.

Starting at $500 per slab section

Why Choose Our Mudjacking (Slabjacking)

Mudjacking is the most cost-effective way to lift settled concrete slabs. We drill small holes (1-5/8"), pump cement-sand slurry beneath the slab to fill voids and lift it back to level, then patch the holes. Most jobs are completed in a few hours and the surface is immediately usable. Mudjacking is ideal for driveways, sidewalks, garage floors, patios, and stoops.

FAQs About Mudjacking (Slabjacking)

How long does mudjacking last?

Mudjacking provides permanent support — the cement-sand slurry hardens to a solid mass beneath the slab. The slab could settle again only if the underlying soil continues to erode or compact, which is uncommon if the void was properly filled.
