The brochure describes a three-layer core. The middle ribs run lengthwise and carry water. The crossed ribs stop the geotextile being pressed into the channels, including under high load.
With geotextile on both sides the composite is presented as filtration, drainage, venting and protection in one sheet.
For landfills the brochure lists groundwater drainage, a leak-detection layer, leachate collection, gas collection in the cap, and surface-water collection on the cap.
