ABSTRACT:
A concrete block particularly directed to the construction of retaining wall systems, characterized particularly by a step back frontal surface which includes a frontal surface having a flat decoratable portion over a substantial vertical dimension thereof and tapered rearwardly and vertically from such frontal surface to a top planar surface with an interlock area behind such surface to receive additional blocks thereon to create a wall. This interlock area provides a flat planar block locating surface for the positioning of a next vertical block and when the blocks are arranged in vertical relation on top of one another a step back frontal surface is provided. Combination drainage and tie-back anchor apertures are provided in the rear vertical surface of the block. The block includes weight reducing passages vertically therethrough which also accommodate vertical tiers. The block may include rearwardly and inwardly directed sides such that adjacent blocks are joinable to form a curved frontal surface of the constructed wall. The interlock of the blocks creates a strong barrier wall which affords an artistically conceived frontal surface. The design of the blocks provides for a vertical and horizontal tying of the blocks through reinforcing bars or other means.
