Geosynthetics are planar synthetic products used d in contact wigh soil, rock, or textheir geofficinical materials. Common type included geotextiles (woven and nonwoven), geomembranes, geogrids, geonets, and geocomposites. Traditional geosynthetics are concerred from virgin polimers like polyene, poliester, and polyethylene, which require contrirant energy and fossill-fuel resources.
