Abstract

Geotextiles, one of the branches of technical textiles, are permeable textile materials or fabrics used for various civil engineering and other geotechnical applications. Geotextiles were one of the first textile products used in human history, and invention of geotextiles forms a bridge between civil engineering and textile technology. The application areas of geotextiles are very wide and during the last decade the areas have expanded further very fast worldwide. With the rapidly growing technological advancement, geotextiles have made inroads into a large variety of domains and have been acclaimed all over the world because of some of their built-in advantages like easiness and flexibility of use, softness (as compared to monolithic and rock constructions), rapidity of installation and long term efficacy. Geotextiles provide a relatively safe and economically feasible solution to day-to-day engineering demands and construction challenges. Used as replacement of natural materials, geotextile products perform a wide range of functions such as erosion control, soil stabilization, filtration, drainage, separation and reinforcement requirements. Geotextile bags, tubes and containers made with geotextiles are playing a proactive role in hydraulic, coastal, offshore engineering and river protection works as eco-friendly, construction-friendly and cheaper alternatives of conventional protection and engineering methods which are generally hard, expensive, temporary (having short life), and not environmental-friendly. The global geotextile market is enjoying strong growth but it is also highly competitive. In this paper, the constructional and functional aspects of geotextiles have been highlighted, and the potential role of various geotextile products in the domain of coastal protection, coastal engineering and off-shore engineering has been elaborated with some real-life ventures both in India and abroad.
