UNIAXIAL GEOGRID: Uniaxial geogrids are designed with the specific purpose of enduring stress in one single direction. They are formed by stretching the ribs in a longitude direction and their tensile strength is stretched in the machine direction. This means they are perfect for both wall and slope applications such as retaining walls, landfill liner systems, embankments over soft soils, and extra steep earthwork slopes. http://www.asntegeosynthetics.com/geogrid/
