Keystone structural products are specifically designed and engineered for optimum efficiency with all system components. Outstanding unit stability and a patented fiberglass pin-connection system have made Keystone, globally, the preferred choice for critical structures including: mine structures, bridge abutments, highway reinforcement and more. These structural products come with designer options such as straight or beveled edge finishes, multi-piece systems, a vast color palette and a number of face textures.
Redi-Rock retaining walls use the power of gravity by using blocks weighing over one ton each. The massive scale of the system allows gravity walls to be built much higher than other wall systems without using geogrid or tiebacks.
Redi-Rock products capture the “Essence of Natural Rock” with textures so natural, many mistake it for quarried stone.
These blocks dry-stack without mortar or footings. The hollow core feature makes them easier to handle and promotes good drainage behind the wall. The raised lip and notch lock each block in place and creates a natural setback. Use one sized block or mix the different block sizes together in the wall to capture the look of hand laid stone. The AB Collection is right at home in residential settings where retaining walls 6’ and under are typically called for, and up to the task on larger retaining walls 6’ and over.
