ABSTRACT:
A reinforced fiberboard box for creating a void in and under concrete formations. A single piece of double faced, corrugated fiberboard is defined by a face, a bottom, a pair of end flaps, and a pair of side flaps. The end flaps are folded into at least four uniformly shaped partitions which are subsequently folded onto the face of the fiberboard and are aligned along the longitudinal axis to create a box-like structure. Pairs of side flaps are then wrapped around the sides and top of the partitions to form a completely closed, internally reinforced, box-like structure. A portion of the side flaps are tucked inwardly, intersecting the partitions so that slots in the side flaps interlock with slots in the partitions which prevents the box void from unfolding during use.
