Active rockfall barrier system refers to various types of rockfall barriers are installed and fastened to the mountains or slopes. Compared with passive rockfall barrier system, which is installed beside the roads, the active rockfall barrier system is covering the mountains and prevent the stones and soils from falling down. It is mainly used for preventing.
Common types of active rockfall barrier are galvanized wire rope net, PVC coated wire rope net, tecco mesh, spider spiral rope mesh and hexagonal wire mesh.
