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
