Abstract
A corner block has spaced-apart front and rear sections interconnected by two spaced-apart side sections that jointly define an internal cavity. Upper protrusions are provided on the top face of the block, and inner protrusions are provided inside the cavity at the bottom of the block. The upper and inner 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° relative to the other, the upper protrusions of the lower block interlock with the inner 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 of each other. The corner blocks A and B are alternately stacked upon one another to construct a 90° corner of a segmental wall structure.
