ABSTRACT:
A mortarless concrete block retaining wall is formed from special blocks arranged in set-back tiers and interlocked by special offset pins. Each block is trapezoidal in plan view with a pair of vertical holes behind a relatively wide front face. The holes in adjacent tiers are laterally offset. The pins have opposite end sections which are laterally offset from one another and fit respectively in the offset holes to interlock adjacent tiers in set-back relation. The special pins are rotatably adjustable to interlock the tiers in a straight configuration or in varying degrees of convex and concave curved configurations.
