“Geotextile” means any permeable textile used with foundation, soil, rock, earth, or any other geotechnical engineering-related material as an integral part of a man-made structure or system which is designed to act as a filter to prevent the flow of soil fines or other particles into drainage systems, or to provide planar flow for drainage, or to serve as a cushion to protect geomembranes, or to provide structural support.
