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.
Abstract: A landscaping block having a block body with at least a first side surface, a second side surface, a third side surface and a fourth side surface, and opposed and substantially parallel top and bottom surfaces. The patio block having at least one spacer projection extending outwardly from each of the at least first, second, third and fourth side surfaces. The patio block having at least one spacer locator positioned along each one of the first, second, third and fourth side surfaces. The at least one spacer locator positioned along each side surface has a retaining surface shaped to receive a spacer projection, at least a portion of the retaining surface extending outwardly from the side surface.

Abstract: A block suitable for use in paving, edging or wall applications comprises a lower portion having parallel, substantially vertical side faces that are spaced apart by a first width, and an upper portion having parallel, substantially vertical side faces that are spaced apart by a second width. The second width is smaller than the first width of the lower portion, and the side faces of the upper portion are angled relative to the side faces of the lower portion. The block further comprises a transition portion between the upper and lower portions, having at least one slanted side extending between one or more sides of the lower portion and one or more sides, respectively, of the upper portion.
