    Abstract

    Geonets and geonet composites (or simply geocomposites) have been quite successful in replacing sand drainage layers in many applications, particularly in landfill leachate collection situations in which space is at a premium. This article evaluates four commercially available biplanar geonets and finds remarkable similarity of one to another insofar as comparable flow rates are concerned. It also evaluates one of these products in two different thicknesses with six covering geotextile variations, indicating that geotextile intrusion is significant in reducing flow rates when testing under simulated field conditions, i.e., using compressible and flexible end platens. With the data generated, as well as collecting related physical and mechanical properties, a generic specification is included for this class of geosynthetic drainage products.
