1. A mold for producing at least two molded concrete units from a single mold cavity while simultaneously creating a roughened textured surface on at least one of the sides of each of said concrete units, the mold comprising: a plurality of generally vertical side walls defining a single mold cavity which is open at its top and bottom; and a grate located within and bridging at least a portion of the mold cavity, the grate being oriented generally vertically within the mold cavity and dividing the mold cavity into at least two mold sub-cavities each of which has a size sufficient to form a molded concrete unit, the grate including a plurality of strands configured in a diamond pattern with openings permitting communication between the at least two sub-cavities, and wherein the grate is fixed in relation to the side walls of the mold cavity so tat the grate is retained within the mold cavity when the molded concrete units are stripped from the mold cavity. 2. The mold of claim 1, wherein the grate is fixed at each end thereof to a side wall of the mold cavity. 3. The mold of claim 1, wherein the grate is fixed at each end thereof to a support element that is, in turn, fixed to a side wall of the mold cavity. 4. The mold of claim 1, wherein the grate extends from the top of the mold cavity to the bottom of the mold cavity. 5. The mold of claim 1, wherein the area of the top opening of one of the mold sub-cavities is substantially equal to the area of the bottom opening of said mold sub-cavity. 6. The mold of claim 1, wherein the area of the top opening of each of the mold sub-cavities is substantially equal to the area of the bottom opening of the mold sub-cavities.
