ADS 0401TS 15' x 360' 4oz Geosynthetic Lightweight Non-Woven Geotextile. Our geosynthetic non-woven fabric is made from a continuous polypropylene filament spun uniformly over a flat surface to make a flat, mat-like fiber. The crossed filaments are then thermally bonded together, rather than woven, into a tear-resistant material creating a filtration medium that offers excellent uniformity, puncture resistance and filtration efficiencies.
