Geogrid geocomposite non-woven geotextile slope protection

Product introduction

BIAXIAL GEOGRID COMPOSITER is a composite made of bi-axial polypropylene (PP) geogrid, heat bonded to a long fiber non-woven polyester geotextile that acts as a filter and soil separator. This geogrid is manufactured using a punching and drawing process whereby the polypropylene sheet is stretched in two directions, machine (longitudinal) and cross-machine (transverse). The result is a monolithic and isotropic geogrid with thick and wide ribs, thick integral nodes, and uniform square apertures. Engineered to be mechanically and chemically stable in aggressive soil environments, THIS-GEOCOMPOSITE allows sub-base drainage to help maintain structural stability, and is very effective in keeping expensive imported material from being contaminated by migration of fines from the saturated base soils.
