Geotextile Woven and Nonwoven
Geotextile definitions. Typically a geotextile has a primary function of separation (preventing aggregate from mixing with subgrade), reinforcement, filtration and drainage or a combination thereof. Geotextiles are selected based upon physical properties required to fulfill those functions. Different manufacturing styles are based upon those functions. Permanent geotextiles are manufactured in polymers such as polypropylene and polyester and short term geotextiles (18 months to 5 years) are manufactured in natural products such as coir.
