Tenax LBO Bi-Oriented Geogrid

GE0 544.1 - E –01/11 TENAX LBO HM 3 Bi-oriented geogrids  TENAX LBO HM geogrids are HIGH MODULUS (HM) bi-oriented geogrids especially designed for soil stabilisation and reinforcement applications. TENAX LBO HM geogrids are manufactured using a unique process of extrusion and biaxial orientation to enhance their tensile properties and overall performance when operating at low strains of 0.5% and 2%. They are manufactured from polypropylene (PP) and tested to maintain a high tensile modulus, high strength junction, as well as an increased durability against installation damage. Typical applications Ground stabilisation reinforcement leading to a reduction of required structural fill in applications such as: airport foundation layers, railway construction layers, road pavement design, foundation and piling platform designs. TENAX GeoRaft structures for reinforced soil mattress and other solutions involving control of differential settlements.
