CornerStone is designed for use in either gravity retaining wall structures or mechanically stabilized, geogrid-reinforced soil retaining systems. CornerStone’s lug design, wedged shape and two-inch lateral allowance in the interlock, make it possible to design 90° and 45° inside or outside corners. Sold by the individual piece.
