Abstract

A wall block (10) comprises an upper surface (16) spaced apart from a substantially parallel lower surface, opposed first and second faces (18, 20 ), and opposed side surfaces (12) converging between respective ends of the fir st and second faces. Blocks in a wall may be stacked on top of each other in either a vertical, set forward or set backward relationship. The length of a block face may be a multiple of its height, and the blocks otherwise are formed such that blocks may be stacked with the top surface of one block in abutment with a bottom surface of a vertically adjacent block or, optionally , with the top or bottom surface of one block in abutment with a side surface of a vertically adjacent block. The blocks may be manufactured in different sizes, such that their faces are of different lengths and heights, thereby enabling the construction of walls or fences of highly variable appearances.
