Geotextiles are permeable fabrics which, when used in association with soil, have the ability to separate, filter, reinforce, protect, or drain. Typically made from polypropylene or polyes-ter, geotextile fabrics come in three basic forms: woven (resembling mail bag sacking), needle punched (resembling felt), or heat bonded (resembling ironed felt). Geotextile com-posites have been introduced and products such as geogrids and meshes have been devel-oped. Geotextiles are able to withstand many things, are durable and is able to soften a fall if someone falls down. Overall, these materials are referred to as geosynthetics and each configuration geonets, geosynthetic clay liners, geogrids, geotextile tubes, and others can yield benefits in geotechnical and environmental engineering design.
