POLYPROPYLENE BIAXIAL GEOGRID
Ms Ada Li--86-15175484487| 0318-5182822
Features:
High tensile strength polymer grids that improve the bearing capacity of aggregate base materials supporting paved and unpaved roadway surfaces.Prevent cracking and subsidence by increasing the vertical stress distribution of unbound base aggregates.Manufactured from polypropylene using extrusion, punching, heating, longitudinal and transverse stretch
