About Needle Punch Non Woven felt

Geotextiles are planar and permeable members which are used in contact with soil/rock and/or any other geotechnical material for civil engineering applications. They are basically textiles manufactured from synthetic fibers . Thus, biodegradation is not a problem for geotextiles. The polymers used in manufacturing geotextiles are Polypropylene, Polyester, High Density Polyethylene and Polyamide (nylon) or a combination thereof, but large majority of geotextiles are made from Polypropylene and Polyester.

We offer geotextile fabric that has the right permeability to ensure that the sand is properly filtered or drained. The properties of our fabric make it an ideal product for various applications like assisting in drainage, controlling erosion, and even increasing the stability of soil. It is available in all forms to aid stabilization, filtration, and separation. You can count on us for your requirement of wholesale geotextile fabric in India. Our staff has been trained to ensure the fabric has a precise composition.

Weak/unstable formations mostly have subsoil and/or subgrade of expansive clays (e.g. Black Cotton Soil). These soils swell when mixed with water, thereby losing shear strength, and shrink on drying. Swelling (due to ingress of water in rainy season) and shrinkage (in dry season) causes disturbance to track parameters and ballast penetration.

This problems can be addressed by reducing ingress of water in the formation, by providing a non-woven geotextile separator layer, which reduces water entering into the subgrade and also ` prevents upward migration of fine particles from fine grained expansive clays into the top coarse layers.

In addition, provision of a blanket layer acts as separator as well as reinforcement layer reducing the pressure on the formation below. In case providing blanket layer of larger thickness in running traffic condition is not possible, its' thickness can be reduced by providing a reinforcement layer of geogrid in the middle of the blanket layer.
