Service life of nonwovens

Q: Where can I find literature on the useful service life of nonwoven geosynthetic fabrics installed in soils?

A: One of the best references in this regard is from a manufacturer of nonwoven geotextiles. It is: 

SI Geosolutions (now Propex). (1997). Smart Solutions, Technical Note, SM-404. “The durability of polypropylene nonwoven geotextiles for waste containment applications.” https://tinyurl.com/GIGeosolutions.  

I would start with this paper and then scour the reference list for additional sources. The above reference is nearly 25 years old but still is relevant and available on the web.
