Stabilisation Of Soils 3D GRIDS

GE0 491.4 - E – 10/10 TENAX 3D Grid Type: MS Bi-oriented geogrids TENAX 3D Grid MS are polypropylene geogrids especially designed for soil stabilization and reinforcement applications. The 3D Grid MS geogrids are manufactured from a unique process of extrusion and biaxial orientation to enhance their tensile properties. TENAX 3D Grid MS features consistently high tensile strength and modulus, excellent resistance to construction damages and environmental exposure. Furthermore, the geometry of the TENAX 3D Grid MS allows strong mechanical interlock with the soil being reinforced. Typical applications Base reinforcement; reduction of required structural fill; load distribution; reduction of mud pumping; subgrade stabilization; embankment stabilization; slope reinforcement; erosion control mattresses.
