3 FT. MIRAFI CUT ROLL 120SQYD NEEDLEPUNCHED NONWOVEN GEOTEXTILE POLYPROPYLENE FIBER FABRIC

Description

MIRAFI^® N-Series nonwoven polypropylene geotextiles combine high water flow rates,
high soil interaction and durability while providing excellent soil particle retention and are used for soil separation, filtration, and drainage in a wide variety of civil and environmental infrastructure projects.

MIRAFI® 140NL is a needlepunched nonwoven geotextile composed of polypropylene fibers, which are formed into a stable network such that the fibers retain their relative position. MIRAFI 140NL is inert to biological degradation and resists naturally encountered chemicals, alkalis, and acids. TenCate Geosynthetics Americas (A Solmax Company) is accredited by Geosynthetic Accreditation Institute – Laboratory Accreditation Program (GAI-LAP). MIRAFI 140NL meets Build America, Buy America Act, Pub. L. No. 117-58, div. G §§ 70901-52.
