  • Retaining wall block
    Publication number: 20040159065
    Abstract: A mortarless concrete block retaining wall is formed from special blocks arranged in set-back tiers and interlocked by a special post groove arrangement. Each block is trapezoidal in plan view with a pair of laterally spaced posts projecting from the top surface of the block. A groove on the bottom surface of the block fits over adjacent posts in the underlying tiers. The vertically adjacent tiers are laterally offset to interlock the tiers via the post/groove arrangement. The post/groove arrangement allows for blocks that are adjustable to interlock the tiers in a straight configuration or in varying degrees of convex and concave curved configurations.
