Mudjacking, which is also called “mud pumping” and “slab leveling,” is a process used to fill the voids and empty spaces that sometimes occur under home foundations and concrete slabs. If you have ever seen lopsided, tilted or uneven slabs of concrete, you have seen what happens when concrete is destabilized due to the voids beneath it. Mudjacking fills those voids, returning stability to the area.
The mudjacking process involves pumping a grout-like mud slurry into holes that are carefully drilled into a concrete slab. As the slurry fills the voids beneath the concrete, it raises the slab, helping to level and stabilize it.
This process is tried and true, and has been used for decades to fix uneven concrete surfaces and concrete settlement.
