CornerStone® is a building material 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 engineered high (30 ft. or more) commercial and industrial geogrid reinforced structures. Whether the design is simple or complex, CornerStone walls retain their strength while flexing under seismic loading. CornerStone is ideal for any size job, no matter the height of the wall.
CornerStone consists of concrete retaining wall blocks with a lug design, wedged shape, and two-inch lateral allowance in the interlock, making it possible to design 90° and 45° inside or outside corners. With two sizes, two face textures, two cap units, and a 90° corner, CornerStone’s segmental retaining wall system can create interesting and visually appealing retaining walls. 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. Whether you are a homeowner looking for a DIY home improvement project for your outdoor space or a contractor looking for the perfect retaining wall blocks, look no further than CornerStone.
In addition to our standard CornerStone series, we also offer nearly zero set back CornerStone 100-Series. These units have a 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.
CornerStone is available for online purchase through the Mutual Materials Online Store.
