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 stabilization. A geotextile is a synthetic permeable textile material used with soil, rock, or any other geotechnical engineering-related material. Geotextiles also called geosynthetics, are generally associated with high-standard all-season roads, but can be used in low-standard logging roads. A geotextile is designed to be permeable to allow the flow of fluids through it or in it, and a geomembrane is designed to restrict the fluid flow.
Geotextiles are mostly used in road construction, especially to fill gaps between the roads to improve soil structure. Geotextile makes poor soil more beneficial for use and then easy to build in difficult places also. Geotextiles are ideal materials used for Construction & infrastructure like roads, buildings, dams, and many more. It improves & stability and decreases the process of wind & water erosion. It helps to prevent the erosion of soil but allows the water to drain off. A Geotextiles made from synthetic or natural fibers associated with soil thin pieces. It improves soil characteristics such as Friction or movement restraint, Support of loads and Changes in bearing failure plane.
Non-Woven Geo Bags (also referred to as geo-tubes, dewatering tubes, erosion control tubes, or geotextile bags) are used for large shoreline protection, erosion control, dewatering, and sludge removal projects. Geotextile tubes are cost-effective solutions for containment, dewatering, desludging, and shoreline protection. Geobags are small soil containers that are made of non-woven geotextile, used for slope protection and river training work. Geobags, also known as Geotextiles Bags, Geotextile Sand Containers or Non-Woven Geobags.
Coir mats are made up of 100% natural fibres. These environmentally-friendly, natural fibres are derived from the husk of the coconut. The husk is the water-resistant layer between the outer coating of the coconut and the hard shell inside. Coir mats are made up of 100% natural fibres. These environmentally-friendly, natural fibres are derived from the husk of the coconut. The husk is the water-resistant layer between the outer coating of the coconut and the hard shell inside. The reason for the strength of the coir fibres is thanks to the tough, thick walls of the fibre made from insoluble cellulose. Coir fibres also have a high level of lignin, a substance found in plants that makes the plant woody, brittle and rigid and reduces the chance of the plant rotting. The natural properties of the coir, or coconut husk, make it ideal for matting as it is water-resistant, strong and durable. Furthermore, the eco-friendly nature of the coir makes it the perfect choice for the environmentally conscious customer.
Nonwoven geotextiles are permeable geosynthetics made of nonwoven materials used along with geotechnical material (soil, rock, etc.) on the integral part of a civil engineering projects. It’s produced mechanically or chemically or by heat-bonding fibres together to form stable fibre network. Nonwoven geotextiles are frequently made polymers from synthetic material like polypropylene, polyethylene, polyamide, polyester, etc. The polypropylene fibre dominates in the geotextile application, cause of its low cost, low specific gravity and strength. But nonwoven geotextiles also made from natural fibres (jute, sisal, coir, etc).
Nonwoven geotextiles are also used in applications where filtration and drainage are required because of its smaller opening sizes and ability to filter smaller particle sizes which allowing water to pass. It is ideal for separation in paving applications in both asphalt and concrete roadways. In concept of barrier application, the nonwoven material can act as a barrier to water infiltration.
In double-lined tunnels, geotextiles are installed between shotcrete and concrete linings to drain ground water that is in the circumferential boundary of the tunnels. During the concrete lining placement, the geotextile often experiences pressures from young concrete on the curved and rough shotcrete surfaces. The pressures are transferred through a waterproof membrane, and act in the normal direction to the curved shotcrete face. The geotextile flow behavior under these conditions cannot be represented by standard geotextile permeability tests. Instead, it requires specially designed performance tests that consider field conditions
