ABSTRACT:
The present invention is a family of concrete segmental retaining wall blocks, together with the related manufacturing process and molds, and retaining walls constructed of such blocks. The segmental retaining wall blocks are used to form retaining walls by dry stacking one course of blocks on another. The preferred blocks are characterized by: (a) a lower surface and a generally planar upper surface in which the upper and lower surfaces permit generally parallel alignment between the upper surface of a block and the upper surface of adjacent blocks in the next adjacent course of blocks when the blocks are stacked to form a retaining wall; (b) a downwardly projecting lip to aid in the creation of the desired setback and to facilitate positioning successive courses of blocks in a wall without the use of separate pins or mortar; (c) sidewalls which converge in a rearward direction to facilitate the construction of curved walls; and (d) a decorative front face which may be formed by splitting cured blocks. The converging sidewalls may include notches or indentations, and the blocks may be provided with handles in the form of depressions or cores.
