US 1540

Woven Filtration

US 1540 is a woven monofilament filtration geotextile made of 100% high-tenacity polypropylene yarns. This product's Percent Open Area of 15% gives it excellent hydraulic properties, while reducing the chances of clogging. US 1540 resists ultraviolet and biological deterioration, rotting, naturally encountered basics and acids. Polypropylene is stable within a pH range of 2 to 13. US 1540 meets the following M.A.R.V. values except where noted:
