Abstract:
1. A wall block system comprising: a plurality of right-hand blocks, each right-hand block having a set of three leveling pads extending from a bottom surface; and a plurality of left-hand blocks, each left-hand block having a set of three leveling pads extending from a bottom surface, the right-hand and left-hand blocks having the same dimensions, wherein when arranged in alternating courses of right-hand blocks and left-hand blocks offset from one another in a running bond pattern to form a wall structure, the three leveling pads of each of the right-hand blocks and each of the left-hand blocks are configured to align with corresponding leveling pads from two abutting blocks in a course of blocks immediately above the block and to align with corresponding leveling pads from two abutting blocks in a course of blocks immediately below the block; wherein each right-hand block and each left hand block has a top surface opposite the bottom surface, a front surface and a rear surface opposite the front surface which extend between the top and bottom surfaces, and a first side surface and a second side surface opposite the first side surface and which extend between the front and rear surfaces, and wherein: each right-hand block has a first leveling pad a first distance from the first side surface, a second leveling pad a second distance from the second side surface, and a third leveling pad a third distance from the first side surface, and each left-hand block has a first leveling pad at the first distance from a centerline of the left-hand block toward the second side surface, a second leveling pad at the second distance from the centerline toward the first surface, and a third leveling pad at the third distance from the centerline toward the second side surface, and wherein the first and third leveling pads of a right-hand block align with the first and third leveling pads of one left-hand block of a pair of abutting left hand blocks in a course of blocks immediately below the right-hand block, and the second leveling pad of the right-hand block aligns with the second leveling pad of the other left-hand block of the pair of abutting left hand blocks in the course of blocks immediately below the right-hand block.
