Tenax Triplanar Series Geonets and Geocomposites are primarily used as drainage in landfill applications. Tenax Tendrain and Tendrain II are typically used in leachate collection in landfill liners and leak detection. Tenax Tenflow is typically used for landfill capping, surface water collection and removal system, and landfill gas venting. Tenax is once again manufacturing its Triplanar geonet structures in its Baltimore, Md., facility. Tenax Triplanar Series Geonets are high-performance HDPE drainage structures consisting of thick supporting ribs with diagonally placed top and bottom ribs. The three sets of intersecting strands form unique flow conduits that provide extremely high flow capacity, high compressive resistance and enhanced tensile properties.
