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.
