Profile Geotextiles is defined as permeable textile materials used in contact with soil, rock, earth or any other geotechnical related material as an integral part of civil engineering project, structure, or system. Geotextiles have proven to be among the most versatile and cost-effective ground modification materials. Their use has expanded rapidly into nearly all areas of civil, geotechnical, environmental, coastal, and hydraulic engineering. They form the major component of the field of geosynthetics, the others being geogrids, geomembranes and geocomposites. Based on their structure and the manufacturing technique, geotextiles may be broadly classified into woven and nonwoven. Woven geotextiles are manufactured by the interlacement of warp and weft yarns, which may be of spun, multifilament, fibrillated or of slit film. Nonwoven geotextiles are manufactured through a process of mechanical interlocking or thermal bonding of fibers/filaments. Mechanical interlocking of the fibers/filaments is achieved through a process called needle punching. Needle-punched nonwoven geotextiles are best suited for a wide variety of civil engineering applications and are the most widely used type of geotextile in the world. Interlocking of the fibers/filaments could also be achieved through thermal bonding. Heat-bonded geotextiles should be used with caution, as they are not suitable for filtration applications or road stabilization applications over soft soils. Geotextile Functions The mode of operation of a geotextile in any application is defined by discrete functions: separation, filtration, drainage, reinforcement, sealing and protection. Depending on the application the geotextile performs one or more of these functions simultaneously. There are various applications such as separation, filtration, drainage (transmissivity), reinforcement, sealing function, etc. Areas of Application The major application areas of geotextiles in transportation engineering are flexible paved road construction, drainage applications and pavement overlays. Geotextiles extend the service life of roads, increase their load carrying capacity, and reduce rutting. The weak subgrades the geotextile extends the service life of a flexible pavement section by a factor of 2.5 to 3.0 compared to a non stabilized section. A geotextile effectively increased the pavement sections total AASHTO structural number by approximately 19%. Geotextiles also play a major role in construction of paved roads over areas having high ground water table. Drainage of water from pavements has always been an important consideration in road design; current methods of pavement design have resulted in base courses that do not drain well. Market Scenario Geo Textiles have proven to be versatile and cost effective ground modification materials. Their use expanded rapidly into nearly all areas of civil engineering, geotechnical, environmental, coastal and hydraulic engineering. Geo-Textiles is forecasted to achieve the highest growth rates among the twelve technical textile application areas. The rate of 4.6% per annum between 2000 and 2005 is set to increase to 5.3% per annum during 2005 to 2010. The world demand for Geo Textiles is projected at about 4715 million square meters by 2014 mostly from China and India. Globally the value of the sector is growing at a rate of around 5% a year and accounts for 0.80% share of the total technical textile segment. This share is expected to go up marginally to 2010. It is predicted that global demand for geosynthetics will increase 5% annually to 4.7 billion square metres in 2013. With India is making huge investments in infrastructure development in roads, railways, dams, irrigation projects, airports, seaports, and construction projects where geosynthetics can be used in enhancing design flexibility, cost effectiveness, aesthetics, functionality and long term durability of the civil, marine, environment engineering projects we undertake. Consequently the demand for geotech segment is set to grow phenomenally. Cost Estimation:
