Auroguard Drainage Geocomposites consist of a biplanar HDPE geonet core thermally bonded to one or two layers of non-woven polypropylene geotextile filter fabric. The geotextile filters fine soil particles from entering the geonet drainage plane while the open-structured geonet transmits water laterally at high flow rates even under sustained compressive load. Applications include retaining wall back-drainage (replacing granular drainage blankets), landfill leachate collection layers between the liner system and waste, highway cut slope drainage, tunnel drainage, and basement wall drainage systems. The roll form allows rapid installation in tight spaces and eliminates the need for aggregate fill drainage layers, saving construction time and cost. Auroguard supplies single-sided and double-sided (geotextile on both faces) variants.
