US 230C

Woven Filtration

US 230C is a woven filtration geotextile made of 100% high-tenacity polypropylene yarns. It  is a "combination" product made of monofilament yarns in the machine direction and fibrillated yarns in the cross direction. US 230C resists ultraviolet and biological deterioration, rotting, naturally encountered basics and acids. Polypropylene is stable within a pH range of 2 to 13. US 230C meets the following M.A.R.V. values
