| Summary: | Geosynthetics is the term used to describe a range of generally polymeric products used to solve some civil engineeringproblems. The term is generally regarded to encompass eight main product categories: geotextiles, geogrids, geonets,geomembranes, geosynthetic clay liners, geofoam, geocells (cellular confinement) and geocomposites. The syntheticpolymeric nature of these products makes them suitable for use in the ground where high levels of durability arerequired. Not only because, properly formulated, they can also be used in exposed applications. Geosynthetics areavailable in a wide range of forms and materials, each to suit a slightly different end use. These products have a widerange of applications and are currently used in many civil, geotechnical, transportation, geoenvironmental, hydraulic,and private development applications including roads, airfields, railroads, embankments, retaining structures,reservoirs, canals, dams, erosion control, sediment control, landfill liners, landfill covers, mining, aquaculture andagriculture. The paper presents basic aspects of geotextiles, drainage, geocomposite designissues and technicalsolutions of their use.
