PP Biaxial Composite Geogrid – A Variety of Sizes for Your Option

PP biaxial composite geogrid is a compound product made of PP geogrid and PET geotextile and manufactured by bonding a biaxial geogrid to a nonwoven polyester geotextile. It features high tensile strength at both longitudinal (MD) and transverse (TD) directions. It is especially designed for soil stabilization and reinforcement applications.

  • Combining the function of reinforcement, filtration, separation and drainage in just one product.
  • High resistance against installation damage.
  • High resistance against biological and chemical degradation.
  • Nonwoven geotextile firmly bonded between uniformly extruded PP.
  • Quick and easy to install.
  • Project reference can be supplied for your bid.
  • ISO certificated factory.
  • CAD or 3D drawing can be supplied for your design and construction.
