Advantages Of Geo-Synthetics

Geo-Textiles and geo-synthetics

Geotextile:

A planar, permeable, polymeric (synthetic or natural) textile material, which may be nonwoven, knitted or woven, used in contact with soil/rock and/or any other geotechnical material in civil engineering applications.

Geotextile is a part of technical textile which is used for special purposes. Geotextiles form one of the two largest groups of Geo synthetics. The raw material of geotextile comes from polyester, Polyamide, Polypropylene and Polyethylene. The application of geotextile is civil engineering, coastal engineering and also huge used of construction site. Generally, geotextiles are located in the tension area to make stronger the soil.

Geo-synthetics:

A planar, polymeric (synthetic or

Drainage:

The use of geotextiles in drainage has made significant strides in changing the conventional procedure of using graded filters. Outstanding advantages of geotextiles in drainage are:

It eliminates the filter sand with the dual media backfill.

 In some cases, it eliminates the need for perforated pipes.

 In situations where only sand backfill is available, it is possible to wrap the drainage pipe with fabric to act as a screening agent. The fabric, thereby, prevents the sand from entering perforation in the pipe.

With Geotextiles, trench excavation is considerably reduced.

 Many times the use of geotextiles eliminates the need for trench shoring. Needle-punched nonwoven geotextile is preferred where drainage is the primary functional requirement.

5. Protection:

Lining is used for cushioning and protection of membrane used for applications such as land fill and waste containment from puncture or training by sharp stone or stress. Geotextiles can also be impregnated with polymeric or mineral sealing materials such as bentonite clay to provide flexible barriers to mixture. Usually spun bond or needle-punched nonwovens are preferred for such

These are the properties that produce the required working effect. They are all developed from the combination of the physical form of the polymer fibers, their textile construction and the polymer chemical characteristics. For example, the mechanical response of a geotextile will depend upon the orientation and regularity of the fibers as well as the type of polymer from which it is made. Also, the chemical resistance of a geotextile will depend upon the size of the individual component fibers in the fabric, as well as their chemical composition – fine fibers with a large specific surface area are subject to more rapid chemical attack than coarse fibers of the same
