Geotextile materials

Geotextiles are widely used in developed nations to overcome numerous geotechnical engineering-related problems efficiently, safely and economically. Geotextile materials may be of a nonwoven, woven, knitted, netted, sandwiched or composite stracture. The use of geotextiles is specific to the location, so in addition to the inherent... 

The degree of benefits obtainable by geotextile materials in a soil—fabric aggregate system depends on the property of the soil as well as the fabric used. Only a suitably designed geotextile material is believed to perform a function separately or in conjunction in various application areas. The most commonly used plain woven jute and coir geotextiles are shown in Figs 4.5 and 4.6. 

Acceptance of a geotextile material should be based on ASTM D4759. 

Composite geotextiles are formed by the integral combination of two geotextile types into a single (composite) geotextile material nonwoven plus nonwoven or woven plus nonwoven. The resulting composite stmcture exhibits the positive attributes of both component parts. Fig. 20.1(c) shows the stmcture of a woven—nonwoven composite geotextile.
