ABSTRACT:
A retaining wall system is constructed in several distinct layers. Each layer is formed of a side-by-side arrangement of I-shaped subassemblies with backfill cheers defined between each pair of subassemblies. Each subassembly is constructed of generally planar elongated concrete blocks which interconnect to laterally secure the blocks to one another. Interconnections are provided by dovetail joints in which a tongue is vertically slid into a groove to prevent lateral separation. The dovetail elements extend only partially across the face of each block so that the block defining the groove is not excessively weakened by the groove.
