Abstract
A retaining wall block system having multiple sizes and shapes of blocks (10 0a- 100f, 200a-200e) with differently dimensioned, interchangeable front and bac k faces. The blocks (100a-100f, 200a-200f) are used to construct an irregularl y textured wall having a weathered, natural appearance. Multiple channels (122 a, 124a, 126a) in the lower face (104a) of the block are used to engage pins (3 0) in pin receiving apertures (137a) to form an attachment system. Aside connection system in particularly useful for stabilizing free-standing walls . Horizontal reinforcing members (20) are also used in the channels (122a, 124 a, 126a) and vertical reinforcing members (10) are used in cores (116) of adjacent blocks for reinforcing a wall. Reinforcing geosynthetic material (7 0) can also be firmly held in a wall by means of the pins (30) or by connectors (50) adapted to fit in the block channels.
