Mudjacking

Mudjacking is a process where concrete slabs are lifted and/or moved using a complex hydraulic system. Small holes are drilled in the surface of the slab through which a slurry is pumped into the area below the slab foundation. This slurry can be pumped in to fill any voids that have developed under the concrete slab, leveling out the foundation and preventing further settlement. The semi-liquid, which is under pressure, can also be used to lift sagging sections of concrete that may require leveling to their original position. Mudjacking cost can vary depending on the amount and number of slab sections needed for leveling. After lifting, the small holes are patched with concrete.
