Abstract

A corner block has spaced-apart front and rear sections interconnected by two spaced-apart side sections that jointly define a through-cavity that extends through the block from a top face thereof to a bottom face. Upper protrusions are provided on the top face of the block, and lower protrusions are provided inside the cavity at the bottom of the block. The upper and lower protrusions are configured and arranged relative to one another so that when two corner blocks are stacked one atop another with one block rotated 90 degrees relative to the other, the upper protrusions of the lower block interlock with the lower protrusions of the upper block to interlock the two blocks. The corner blocks are constructed in two variants, a corner block A and a corner block B, which are mirror images or opposite hands of each other. The corner blocks A and B are alternately stacked upon one another to construct a 90-degree corner of a segmental retaining wall or other wall structure. Each corner block has two exterior sides, and the two exterior sides of each successive corner block are set back or offset from the two exterior sides of the preceding block by a predetermined setback.
