Use Redi-Rock blocks to create walls for erosion control, shoreline protection, landscaping needs, or even golf course tee boxes. Look like natural rock, yet come in a variety of shapes, colors, and textures, including cobblestone and limestone finishes. Tapered sides allow creation of convex or concave walls, 90 corners, or circular patterns. Can reach up to 13-ft. heights without requiring geo-grids or tiebacks. Full blocks measure 18 ins. high, 46 ins. wide, and 24 to 41 ins. deep. Weigh between 1,300 and 2,400 lbs. Also come in 23-in.-wide half blocks. Self-aligning knob and groove system interlocks blocks. One or 2 workers can install by using small excavator, skid steer, or backhoe.
