Not much pressure is required to do this since concrete slabs don t weight too much.

The mixture which is like thick mortar easily raises the sunken slab. Holes are bored through the sunken slab. In time however concrete slabs can crack or sink due to pressure or from movement during settling. This process is much the same as mud jacking an older method that uses a concrete slurry mixture to obtain the same results.
