Continuous grid beam structures made of shotcrete have been used for over 30 years in Japan to stabilize natural and man-made cut slopes. This slope stabilization structure, generally called “Grid Beam,” is widely applied in Japan. It was used in more than 4600 slope  stabilization sites in Japan in the year 2002 alone. The Grid Beam system is often used independently to protect slope surfaces from erosion, or used as a supporting structure, combined with ground anchors or soil nails to stabilize the slope against failures. The area surrounded by the beams is often revegetated to improve aesthetics and harmonize the installation with the surrounding environment . Due to the geometric flexibility of this system, the concrete beams can easily follow the undulations of natural slopes and maintain good contact with the surface.
