When you are dealing with cracked and settling concrete, there are typically two ways to fix the problem: replace the slab with new concrete or raise the slab by pumping a mortar-based mixture underneath the settling slab in a process known as mudjacking.

Mudjacking, slabjacking, and slab raising are all terms to describe the same process. Mudjacking, a concrete lifting technique, has long been an effective alternative to replacing sunken or uneven concrete slabs. Raising settled concrete is much less expensive than concrete replacement.

The problem with traditional mudjacking is that the weight of the “slurry” mixture that is pumped under the slab, combined with the weight of the concrete itself, can actually cause the slab to sink further if the soil beneath isn’t able to support the load.
