Abstract
A slab jack assembly for raising a fragmented slab from between sections of a concrete slab from which the fragmented slab is cut comprises a planar support positionable on top of the fragmented slab. Jacks are mounted on opposite sides of the planar support to engage an upper surface of the concrete slab. Securement pins mounted on the planar support are insertable into holes bored in the plurality of fragments in the fragmented slab and expandable within the holes to secure the fragments to the planar support. The first and second jacks are then operable to lift the planar support and fragments upward relative to the concrete slab.
