Biaxial tensile (polypropylene) geogrid PP bi-directional geogrid is made of polypropylene and high density polyethylene as raw material, through special extrusion and biaxial tension. It can reduce the required structural fill, uniform load distribution, high tensile modulus and tensile strength, high resistance to mechanical damage and durability. It is mainly applicable to soft soil foundation treatment and reinforced soil structure. Construction key points: excavation foundation bed: setting sand cushion (height difference not more than 10cm), rolling into platform, laying grille, vertical axis should be consistent with the main force direction, longitudinal lap 15-20cm, transverse 10cm, lapping with PP bi-directional geogrid at the lap joint, and fixed ground with U nail on the laid PP bi-directional geogrid every 1.5-2m. The laid PP bi-directional geogrid should be in time The number of geogrids laid on the backfilled soil is considered as technical requirements.
