GSE BioDrain LP consists of a GSE HyperNet geonet heat-laminated with a nonwoven geotextile on one side and a low permittivity (LP) woven geotextile on the other side. The geotextile serves as a filter and separator, while the core provides liquid flow medium. The type of geotextile and thickness of the core can be varied depending on requirements of a project.
GSE BioDrain HP consists of a GSE HyperNet geonet heat-laminated with a nonwoven geotextile on one side and a high permittivity (HP) woven geotextile on the other side. The geotextile serves as a filter and separator, while the core provides liquid flow medium. The type of geotextile and thickness of the core can be varied depending on requirements of a project.
GSE CoalDrain geocomposite is available with either a 300 mil (7.6 mm) thick GSE HyperNet or 300 mil (7.6 mm) thick GSE PermaNet geonet heat-laminated with a non-woven geotextile on the bottom side and an innovative composite fabric on the top side. The geotextiles serve as filters and separators, against fine materials like coal ash and FGD gypsum, while the core serves the drainage function. The innovative geocomposite has been tested extensively in the laboratory and the field and has been proven to meet the performance requirements of an effective filter against coal combustion residuals.
GSE MineDrain geocomposite consists of GSE PermaNet 300 or 330 mil (7.6 or 8.4 mm) geonet, heat-bonded on one or both sides with a GSE NW6 nonwoven needle-punched geotextile filter. The creep resistant structure of the round-strand geonet core ensures continuous flow performance over a broad range of conditions and long durations. The geocomposite works as both a great geomembrane protection layer and an efficient drainage medium. As a better alternative to the natural drainage gravels, GSE MineDrain is ideal for extremely high compressive stress applications in the mining industry such as conventional and dynamic heap leach pads, tailings pond and dams.
330 (8.4) mil (mm)
GSE TenFlow AirMax geocomposite consists of a 330 mil (8.4 mm) thick GSE TenFlow geonet heat-laminated on both sides with a GSE nonwoven needle-punched geotextile. TenFlow AirMax geocomposite is a T-shaped tri-axial geonet comprised of HDPE strands forming a three dimensional structure for rapid landfill gas transmission. The geotextile is available in mass per unit area of 6 oz/yd2 or 8 oz/yd2. TenFlow geocomposite provides high transmissivity in a soil environment.
