Geotextiles-What do they do?
The earliest uses of Geotextiles include woven industrial fabrics, waterfront structure, and dam construction in various part of the world. At present scenario the usage of geotextiles has gone far beyond road construction to landfills.
What does geotextile mean?
If you try to analyze the word, you will end up with ‘Geo’ and ‘textile’ where the former means earth and the latter fabrics. As the name suggests the meaning of the word, hence it finds its application in all Geo technical engineering works.
it acts as a separator for different layers of soil. Ultimately it avoids mixing up of two different things.
Shear failure leads to soil movement. The reinforcement function of this material hinders the soil movement. Soil fabric friction property of this material helps in doing so.
This material can be used to construct drainage system because this is highly malleable.
Drainage system gets clogged up due to gravel present in the drain water. Geotextile filters the soil particles from getting mixed up with drain water. It is responsible for the streamlined flow of water in drainage system.
Geotextile protects the walls of the drain from corrosion. It does not allow the leaching of fine material.
Present day usage of Geotextile
1. Construction of Road
Use geotextile prevents the road from runoff. It Increases the stability of the roads. Ultimately the lifetime of the roads gets improved with the use of this material. Different soils require the use of different densities of this material.
2. Protection against flood
This material does not allow puncture. When it is used for protection against flood it provides dual functions. It works both as a filter and puncture preventive.
3. Construction usage
Seepage of water is a big problem in any construction. This material works as a preventive for water seepage in construction of roof and basement.
It is used in landfills as it separates the waste material from getting mixed with the drain water.
Marketing aspects of geotextile
The geotextile available in the market is of two types as woven and non-woven type. This material is biodegradable. There is another type of this material which is called coir geotextile. The marketing of this material is done to common people as a holder of the soil in your locality. This can be used to provide protection against soil corrosion on a long term basis.
This type of geotextile is meant for road usage. It can be used for all types of stabilization and control purpose.
This type of geotextile is used more often than that of the previous type. This is used for all types of filtration, road construction, and drainage. You can use it around pipes and drains for the purpose of filtration. As per the use of this material, this is of three types basing on weight. Small weight, medium weight and heavy weight are the three types of geotextile material used for different works.
There is no other material in the world which can replace geotextile. The growing usage of this material for all civil construction has paved the way for the growing production of this material.
