Abstract:
1. A mortarless retaining wall constructed of a plurality of segmented retaining wall (SRW) blocks stacked in an array of superimposed rows, each SRW block comprising: a face unit having a facing surface defining part of the exposed surface of the retaining wall, the face unit having two connector elements; an anchor unit having two connector elements each being of complementary shape to the face unit connector elements, the anchor unit confronting soil being retained by the retaining wall; the anchor unit and the face unit each having upper and lower load bearing surfaces, the upper load bearing surfaces for mating with the lower load bearing surfaces of a super-imposed stacked block, the load bearing surfaces being generally planar to resist shear forces between adjacent SRW blocks, the shear forces applied by the soil retained by the retaining wall against the SRW block, and the anchor unit and face unit interlocked via respective connector elements to form the SRW block, the anchor unit and the face unit, when interlocked, forming a hollow core bounded by inner walls of the anchor unit and the face unit and extending vertically from the upper load bearing surfaces to the lower bearing surfaces.
