Multifunctional geotextiles

Figure 8.1 indicates that geotextile structures include continuous sheets of non-woven, woven, and warp knitted fabrics, and stitch-bonded fibres or yams. The woven and warp knitted materials can be made to have a similar structure to certain of the textile-related products (essentially geogrids) to be used as alternatives. The non-woven geotextiles can be combined with the textile-related structures to make geocomposite products that are multifunctional.

Geotextiles are those fabrics used in geotechnical applications, such as road and railway embankments, earth dikes, and coastal protection structures, designed to perform one or more basic functions such as filtration, drainage, separation of soil layers, reinforcement, or stabilisation. Therefore, almost every geotextile application is multifunctional. 

Moreover, the development of geocomposites made of a non woven geotextile and a woven geogrid will allow increasing multifunctional use of geotextiles, affording reinforcement, drainage, and filtration capacity.
