Filter fabrics have been available for several years and are used most frequently as an underliner for roadbeds and in other construction related activities. These materials are produced both as woven and nonwoven fabrics and are available in varying weights and porosities. Fabric selection is based on the proposed application and the specifications that the desired material must meet. If filter fabric is selected as the stabilization technology that is to be used, it has the advantage of being available from several manufacturers whose products are competitively priced. These materials, regardless of manufacturer, are relatively inert geosynthetics that are resistant to ultra-violent degeneration.
