'Geotextiles' are permeable fabrics which, when used in association with soil, have the ability to separate, filter, reinforce, protect, or drain. As the use of geotextile fabrics has expanded there has been the introduction of geotextile composites and the development of products such as geogrids and meshes. Overall these materials are referred to as geosynthetics and each configuration—geonets, geogrids and others—can yield certain benefits in geotechnical and environmental engineering design. These products have a wide range of applications and are currently used to advantage in many civil engineering applications including roads, airfields, railroads, embankments, retaining structures, reservoirs, canals, dams, bank protection and coastal engineering.
