CornerStone® is designed for use in either gravity retaining wall structures or mechanically stabilized, geogrid-reinforced soil retaining systems. Applications range from low, lightly loaded gravity designed residential retaining walls to high (30 ft. or more), commercial and industrial geogrid reinforced structures. Whether the design is simple or complex, CornerStone wall retain their strength, while flexing under seismic loading.
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. Concave and convex curves flow with precision. Stairs, with secure railings, can be effectively integrated into any hardscape design. When geosynthetic reinforcement is added, a CornerStone wall becomes a dependable, attractive system that can effectively stylize or promote the natural qualities of a site.
CornerStone is ideal for any size job. CornerStone can be used for both low gravity retaining wall and taller reinforced wall, allowing you the ability to utilize the same wall throughout your landscaping. With two sizes, two face textures, two cap units and a 90° corner, CornerStone can create interesting and visually appealing retaining walls. CornerStone can be used for gravity walls up to 6′-0″ (depending on which units are used) and reinforced walls up to 30′-0″.
In addition to our standard CornerStone series, we are now offering a completely new CornerStone 100-Series. These units have a newly-designed SecureLug interlock system, which reduces the batter between courses from 5/8” with our standard CornerStone units to 1/8”, giving your walls a cleaner sight line along the face. This CornerStone system performs just as effectively as our standard CornerStone system, however, this near-vertical feature does not come with the 200-Series or 50-Series blocks.
