Keystone® Standard III
The updated design of Keystone® Standard III features a wide, open core which ensures sufficient fill placement, enhances connection strength with geosynthetics and reduces overall product weight, making Standard III easy to handle.
Use of high strength fiberglass pins guarantees each Standard III unit is properly aligned and the wall is secure. The Keystone Standard unit is the industry’s most stable construction platform for taller and gravity walls.
