MINNEAPOLIS (May 17, 2018) The Maryland State Highway Administration (MSHA) recently issued approval of the Keystone® KeySystem II™ retaining wall system, using Keystone Compac® II or III and TenCate Miragrid® reinforcement for use on state highway projects for walls up to 50 feet high.

 

KeySystem™ II is designed to the highest standards and unique requirements of the transportation sector. The system consists of Keystone Compac® II or III units and TenCate Miragrid® geogrids by TenCate Geosynthetics. As the leading commercial retaining wall product on the market, Keystone Compac® features an open core design and the pin connection system.
