Name: Mud Dog Concrete Lifting. Descripton:Slabjacking, or, mudjacking, as it is commonly called, is a cost effective alternative to replacing sunken concrete.Concrete is lifted by drilling 1 5/8″ holes through the slab, and pumping, under hydraulic pressure, flowable cement grout underneath the slab. As the mixture flows beneath the surface, voids and depressions are filled and the slab is raised to achieve the desired height.This method of raising concrete can be used to lift sidewalks, stoops, driveways, pool decks, RV pads, garage floors, patios, factory floors, office floors, streets, and runways. Void filling can also be performed for stabilization and to fill holes caused by animals or soil erosion.Concrete raising is the alternative to costly replacement. Mud Dog Jacking is committed to providing top quality services to homeowners, schools, churches, municipalities, property managers, and local businesses.
