GEOSYNTHETICS

GRW protective barriers constitute pentagon-shaped vertical bags, connected side by side like an accordion to make a continuous cellular  barrier. They are linked together to create barriers 100 ft. long or more and are filled with one of a multitude of products such as locally available sand, river silt, gravel, crushed stone, or concrete. The deployment units are removed immediately after filling and leapfrogged ahead to the next set of cells, where the process is repeated for whatever continuous length is required.
