Abstract: A lightweight concrete masonry unit for veneering the face of a building. The veneer block includes a body with planar front, top, bottom, and side surfaces with the top, bottom, and sides perpendicular to the front surface. One or more channels are formed in the rear surface. The depth of the channels are restricted to maintain no less than one inch of remaining wall thickness between the channel bottoms and the opposite front surface. The novel shape and larger minimum wall thickness of the lightweight veneer block enables production on a commercial block machine within the standard cycle time, provides weight and raw material cost savings up to 50%, and allows block heights that are not attainable with conventional hollow core veneer blocks.

Abstract: A block for use in constructing a retaining wall and comprising a body having a central cavity extending vertically there through and defining front, rear, and side walls. The side walls diverge rearwardly from the front of the block to the rear. Stabilizing wings extending outwardly at the rear of the side walls. Positioning wedges extend from the bottom surface and include flat forward surfaces for positioning the block with respect to the blocks in a lower tier of blocks. The flat forward surfaces of the positioning wedges are located nearer the front surface of the block than is the inner surface of the front wall, thereby enabling a retaining wall created from the blocks to have each successive higher tier offset from the adjacent lower tier by a set distance. The block of the present invention provides a stable block having a large coverage area at a low weight.
