GEOTEXTILE

Geotextiles are permeable fabrics which are normally manufactured by either woven or non-woven techniques.

USES OF GEOTEXTILE

There are five main functions that geotextiles are meant to perform:

Separation Reinforcement Filtration Protection and Drainage.

TYPES OF GEOTEXTILE

WOVENWoven geotextiles are manufactured by weaving together narrow strips of film.

NON WOVEN GEOTEXTILESThe manufacturing by of needle punching as opposed to weaving
