HV Geogrid 3D Mat for Erosion Control
HV Geogrid is a flexible three-dimensional geocomposite mat made of three jointed nets with a volumetric configuration.
HV Geogrid is a reinforcement grid of high tensile strength and low defromation.
The open and volumetric structure of HV Geogrid allows to retain soil layers on slopes, offering an increasement of the friction angle between the cover soil and the rest of geosynthetics (geomembrane, drainage geocomposite or bentonite clay linner). In addition, the high tensile strength and low creep of HV Geogrid assures a long term reinforcement of the slope.
