US 220/220PET is a woven geotextile comprised of high tenacity polyester yarns woven into a stable network such that the yarns retain their relative positions. US 220/220PET is inert to biological degradation and naturally encountered chemicals, alkalies and acids. US 220/220PET has been developed to reinforce steepened slopes, embankments over soft soils and landfill liners. US 220/220PET meets the following M.A.R.V. values:
