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.
A corner block having spaced-apart front and rear sections interconnected by two laterally spaced-apart side sections that jointly define an internal cavity that extends completely through the block from a top face thereof to a bottom face thereof, an upper protrusion protruding upwardly from the top face of the rear section rearward of the cavity, and two lower protrusions protruding from a wall of the cavity into the cavity at a bottom portion of the block, the two lower protrusions being spaced apart to define a gap therebetween, and the upper protrusion being located and dimensioned relative to the two lower protrusions so that two corner blocks that are mirror images of one another can be stacked one atop the other with the upper corner block rotated 90 degrees relative to the lower corner block and the upper protrusion of the lower corner block fitted into the gap between the two lower protrusions of the upper corner block to interlock the upper and lower corner blocks.
A corner block having spaced-apart front and rear sections interconnected by two laterally spaced-apart side sections that jointly define an internal cavity that extends completely through the block from a top face thereof to a bottom face thereof, an upper protrusion connected to and protruding upwardly from the top face of the rear section rearward of the cavity and that fits in a gap between two protrusions provided in the internal cavity of an upper corner block which is rotated 90° relative to the corner block and stacked atop the corner block, and two lower protrusions that protrude from a wall of the cavity into the cavity at a bottom portion of the corner block in spaced-apart relation to define a gap therebetween into which fits the upper protrusion of a lower corner block which is rotated 90° relative to the corner block and stacked beneath the corner block.
