Geosynthetics is a generic name representing a broad range of products, such as geotextiles, geogrids, geonets, geomembranes, geocells, geofoams and geocomposites. They are manufactured under controlled conditions, mainly from the synthetic polymeric materials (e.g., polypropylene, polyester, polyethylene, polyvinyl chloride, polyamide and polystyrene). Geosynthetics are designed for use in contact with soil, rock and/or any other civil engineering-related material as an integral part of a human-made project, structure, or system.
Geonaturals (products based on natural fibres), such as jute, coir and bamboo, are also being used in contact with soil, rock and/or other civil engineering-related material, especially in the temporary/short-life ground applications. In fact, the geonaturals are also polymeric materials since they contain a large proportion of naturally occurring polymers such as lignin and cellulose, and they are a part of geosynthetics
Utilisation of geonaturals must increase in years to come to achieve sustainability. Fibres from natural and waste products also help greatly in achieving sustainability in ground infrastructure developments. They are also being studied along with geosynthetics.
