Grille Type: Uni-direction
Prickle: m2
Product Introduction: Uni-direction geotechnical grid of plastic is a kind of geotechnical material with high strength that uses molecule polymer as main raw material, adds certain ultraviolet proof and aging resistance agent and makes messy chain shape molecules have directional layout and from linear status by unidirectional extension .Plastic geotechnical grid makes directional tension under certain tempeture condition according to physcial features of high molecule polymer, so its strengrh is very high in tesion direction, tension resistance reaches 100-200Mpa, yield elogation rate is only 4-10% , it is near to the level of low carbon steel and much better than traditional or current reinforcement materials, and is very ideal synthetic materials for strengthening and reinforcement of civil projects.

Product Features
1. High unidirectional tension resistance, good creep resistance and stable chemical nature.
2. It has large friction factor with sandy stone.
Application Range
1. It is mainly used in retaining wall, bridge abutment steep slope project and so on.
2. Retaing wall and bridge abutment belong to force bearing structures and bear all externall loads such as active soil pressure , support of structure upper part and temperature stress.Under the function of large tension and repeated function of dynamic load, molecule structure of reinforcement material occurs fatigue, its performance occurs attenuation and aging of grid quickness.In order to avoid large deformation of structure caused by creep of reinforcement material, undirectional geotechnical grid with high-density polyethylene( HDPE) as raw materrial shall be used.
