A system is taught comprising a first plain end concrete structure comprising two side faces extending horizontally to end in two end faces and a second fork end concrete structure comprising two side faces extending horizontally to end in two fork ends; said fork ends each comprising a pair of fork walls that define a slot. The system further comprises a base and a rigid support member embedded in the base, and received within said slot. The slot has a width sized to receive an end face of the first plain end structure such that the end face of the first plain end structure is disposed adjacent the rigid support member. A system of stacked structures is taught, said system comprising one or more stacking structures, each comprising two side faces extending vertically to end in a bottom face and a top face, said top face comprising a top profile and said bottom face comprising a bottom profile. The one or more stacking structures are vertically stackable onto each other such that the top profile of a lower structure interfits with the bottom profile of a higher structure in the vertical stack. |
