Abstract
A novel concrete block having six generally planar faces to provide a retaining wall for retaining a bank of earth. The retaining wall includes a lower tier of a plurality of separate abutting bottom blocks; an intermediate tier of a plurality of separate abutting intermediate blocks; and at least one upper tier of a plurality of separate abutting blocks. Each concrete block of each tier has six generally-planar faces, consisting of two planar end faces, a front planar face and a rear planar face, the front planar face and the rear planar face having a plurality of drainage ducts extending therebetween, an upper planar face and a lower planar face. Each upper planar face differs from the lower planar face of each block by a particular recited structure. As well, particularly defined locking interrelationships are provided between the individual blocks of the tiers of blocks.
