GSE RoaDrain 7 geocomposite consists of a tri-planar geonet heat-laminated on both sides with an 8 oz. nonwoven needle-punched geotextile. This product quickly removes subsurface water from pavement base and sub-base layers, while providing a void-maintaining system to work as a capillary break. RoaDrain 7 also works as a separation layer, as well as a replacement of natural stone drainage layers directly under highway pavements.
