The family covers geotextiles, geogrids, geomembranes, geosynthetic clay liners, geonets, geocells and the geocomposites made by combining them. Each product is chosen for one or more functions: separation, filtration, drainage, reinforcement, containment or protection. Most are made from polypropylene, polyethylene or polyester, with PVC and other polymers for special cases.
Bid package has five geosynthetics in one cell, so the CQA plan runs to forty pages.
