Abstract:
1. A wall block for use in a segmental retaining wall system, the wall block comprising: an interior block face for forming an interior surface of a segmental retaining wall; an exterior block face for forming an exterior surface of a segmental retaining wall; first and second block sides that extend from the exterior block face to the interior block face; a block top surface having a lock channel formed therein, the lock channel being defined by a channel front wall, a channel rear wall, and a channel bottom surface, the lock channel extending across the block top surface from the first block side to the second block side, wherein the channel front wall includes a first shoulder that extends towards the interior block face so as to overhang a portion of the channel front wall, wherein the channel rear wall includes a second shoulder that extends towards the exterior block face so as to overhang a portion of the channel rear wall, and wherein the shoulders run generally parallel to each other along the lock channel to define an opening that is narrower than the width of the lock channel in the area between the channel opening and the channel bottom surface; and a block bottom surface having a lock flange, the lock flange including a flange front surface extending from the block bottom surface, a flange rear surface extending from the block bottom surface, and a flange bottom surface extending between the flange front and rear surfaces, the lock flange extending across at least a portion of the block bottom surface in substantially the same direction as the lock channel and being sized, shaped, and positioned such that when the block is placed on top of a similarly configured block the bottom of the lock flange can pass through the opening of the lock channel of the similarly configured block to couple the blocks together.
