Flammability? Zip ties? MARV? Ponds? GT specs?
Questions and answers from the GMA Techline.
I am a student of hydraulic structures and I need some data about transmissivity of geotextiles (ASTM D4716 or ISO/DIS 12958); and also permittivity or cross-plane permeability (ASTM D5493 or every
My thesis is about transmissivity and permittivity of geotextiles in the long-term.

There is limited data available on either transmissivity or permittivity for the simple reason that these properties vary considerably with the specific type of geotextile being considered. Perhaps the best publicly available database is in the annual Specifier’s Guide by Geosynthetics magazine. Contact Ron Bygness, the senior editor, at email@example.com and he might have a copy for you.
