XR-5 Geomembrane Liner
8130 XR-5 is a state of the art geomembrane compatible with a wide range of harsh liquids. It is an extremely tough woven synthetic fabric of DuPont Dacron Polyester which has been molecularly coated with sophisticated compounds that are minimally degradable in adverse environments. This design eliminates liner failure caused by "wicking" as can be experienced by laminates. Delaminating is also impossible as XR-5's exclusive molecular primers saturate its woven fibers bonding the substrate and coating compound into a single system. XR-5 also exhibits impressive dimensional stability, tensile strength and puncture resistance. Maximum strength to weight ratios and superior flexibility are other qualities which XR-5 delivers. In plant fabrication and on-site installation go quickly. Time and money are saved and quality is assured.
Typical Installations of XR-5:
Solar Ponds Emergency Containments Brine Ponds Secondary Containment Industrial Lagoons Crude Oil Holding Pits Chemical Holding Basins Wastewater Lagoons Hazardous Waste Impoundments Tailing Ponds
Applications suggested are not intended to be all inclusive, nor does GeoCHEM warrant or guarantee the suitability or longevity of this material for the uses listed. Your project engineer or installer/contractor is your best advisor in determining what physical properties are required for a synthetic liner. In some cases a chemical compatibility test may be required.
Delamination is Impossible
