The RidgeWall segmental retaining wall system is a large format modular system primarily used to retain and stabilize large and small areas of earth, through both sheer weight and strategic design. The RidgeWall system provides a number of unique features, and can easily be installed vertically, in-set, out-set or reversed for a smooth modern design on the opposing side.
