ABSTRACT:
A layered geosystem and method employ at least one layer of geotextile which has at least one surface friction-treated with a treatment material in a manner described herein. Contact of the friction-treated surface with an adjacent layer of, for example, geonet or geomembrane assists in preventing movement of such a layer which can occur on sloped terrain.
