Concrete lifting is the process of raising sunken concrete slabs to their original level. Lifting can be done with a variety of methods, but the most common are mudjacking and concrete lifting. Mudjacking is cheaper but slower than concrete lifting, which is more expensive but faster.
Mudjacking is a process where a mixture of water, sand and cement are injected under pressure into the slab or footing that has sunken below grade level. The pressure causes the mixture to expand and to fill any voids in the soil beneath the slab or footing. As it hardens, it provides support for the slab or footing that has sunken below grade level. Mudjacking is a one-time cost that can be expensive depending on the size of the project. More often than not, a project will be hired out and have the mudjacking done by professionals.
Concrete lifting is an alternative solution for raising sunken slabs that have not been penetrated by water or other liquids from below ground level. Concrete lift involves using steel cables attached to a hydraulic jackhammer to pull up on one end of a slab while at the same time pushing down on another end of a slab with a backhoe or bulldozer.
