Abstract

A retaining wall having a plurality of courses of retaining wall blocks including a first upper course and a second lower course. Each retaining wall block has opposed front and rear faces, opposed first and second side surfaces, and opposed and substantially parallel upper and lower surfaces, and at least one weight bearing pad extends from one of the upper and lower surfaces. The at least one weight bearing pad extends substantially from the rear face to the front face of the block. The weight bearing pads are the only areas of contact between the blocks in the first upper course and the blocks in the second lower course.

Claims

1. A wall block comprising a block body having opposed front and rear faces, opposed first and second side surfaces, and opposed and substantially parallel upper and lower surfaces, at least one weight bearing pad extending from one of the upper and lower surfaces.

2. A building unit comprising a body having opposed front and rear faces, opposed first and second side surfaces, and opposed and substantially parallel upper and lower surfaces, at least one weight bearing pad extending from one of the upper and lower surfaces.

3. A building unit for forming a portion of an exposed surface of a wall of a structure, the building unit comprising:

a body with a front face opposed to a compound shaped rear face, the front face forming a portion of the exposed surface of the wall, opposed first and second side surfaces, and an upper surface opposed to a lower surface, the compound shape of the rear face of the body having two or more rearmost surfaces and two or more recessed surfaces, the building unit having two or more weight bearing surfaces extending a height from the upper surface of the body, each weight bearing surface having a horizontally planar surface, the horizontally planar surface of each weight bearing surface being the uppermost surface of the building unit;

wherein the body has a front portion extending from the front face to the two or more recessed surfaces of the compound shaped rear face and a rear portion extending from the two or more recessed surfaces to the two or more rearmost surfaces of the compound shaped rear face and wherein the two or more weight bearing surfaces extend along the upper surface of the body from the front portion to the rear portion of the body beyond each recessed surface of the compound shaped rear face.
