Drainage Geocomposite is a geo-combination of Geonet1 and Nonwoven Geotextile on one side or double sides to improve drainage of roads or projects demanding high performance of drainage, filtration, load distribution and protection. Nonwoven Geotextiles are laminated to bi-planar geonet core on one side or both sides for the integrated property of both separation and leachability. The Geocomposite, however, retains the capability of both, i.e., permeability and void-maintaining. Our Drainage Geocomposite enables excellent erosion protection, separation and fluid transmission, equivalent to free drainage base materials, transmission, equivalent to free drainage base materials.
