Geosynthetics include a variety of synthetic polymeric materials that are specially fabricated to be used in geotechnical, environmental, hydraulic and transportation engineering applications. The main functions of geosynthetics are defined by ISO 10318-1 standard, while the pictograms associated to each function are standardized by ISO 10318-2 standard. It is convenient to identify the primary function of a geosynthetic according to these ISO documents, also considering that few geosynthetics perform only one function. The main functions profiled in this leaflet include Separation, Filtration, Drainage, Barrier, Surface Erosion Control, Reinforcement, Stabilisation, Protection, and Stess Relief.
