US 670

Woven Filtration

NTPEP APPROVED - GTX-2019-01-285. US 670 is a woven, monofilament filtration geotextile made of 100% high-tenacity polypropylene yarns. A Percent Open Area of 4 - 6%, gives it excellent hydraulic properties, while reducing the chances of clogging. US 670 resists ultraviolet and biological deterioration, rotting, naturally encountered basics and acids. Polypropylene is stable within a pH range of 2 to 13. US 670 will satisfy the requirements as outlined in AASHTO M-288-06 for Permanent Erosion Control & Subsurface Drainage Class 2 & 3 (>15% fines) and meets the following M.A.R.V. values except where noted:
