What is Mudjacking?

Mudjacking is the process used to raise sunken concrete back to its original level. Mudjacking can be used to repair good slabs of concrete around your home instead of tearing them out and re-pouring them, usually at a fraction of the cost of replacement.

How does it work?

Small holes are drilled into the sunken slab and a grout-type of material is pumped under the slab through the small holes. The material fills any void and then lifts the slab back into position. The holes are patched with cement and the surface is ready to use.

 Why do concrete slabs sink?

Concrete slabs sink for a variety of reasons including soil erosion, poor soil preparation, and soil movement. The slab sinks because there is less soil under it to support it.

Benefits of mudjacking

Mudjacking is practical and generally easier and less expensive than replacing the entire slab. Mudjacking replaces the missing soil with a sturdy material that is not prone to erode or shrink. The only evidence of the process is the small holes drilled in the concrete which are patched with concrete and usually matches well with the existing concrete. Mudjacking can actually look better than removal and replacement because the original slab matches the surrounding slabs.
