Introduction: Non-Woven Geotextile are needle punched fabrics made from polypropylene. The dry laid needle punch technology is based on a two step process. Firstly, polypropylene resin is extruded into fibres. Secondly, the fibres are carded and needlepunched. Finally, some types are added thermal treatment. Weights range from 100 g/m2 up to 1200 g/m2.   Functions of Non-Woven Geotextile: Primary Functions: Separation The durability and mechanical properties of Non-Woven Geotextiles make them ideal as separating layers in construction works. To prevent mixing of construction layers. To improve the compaction properties of the aggregate layer. To increase bearing capacity by avoiding material loss into the subgrade. To provide long-term stability of foundation layers.   Filtration The characteristic opening size of Non-Woven Geotextiles is designed to retain particles while allowing free movement of water, making it possible to separate two layers during intense hydraulic activity. To avoid migration of fine material into coarse material as a result of water flow in the soil. To maintain the water flow in the soil with minimum pressure loss. To prevent migration of fine material as a result of pump effects from dynamic loads such as traffic.   Protection When placing a Non-Woven Geotextile on both sides of a waterproof membrane, the thickness and strength of the geotextile protect the membrane from puncture. To ensure the integrity of a sealing material when fill material and/or loads are applied. To protect a membrane and at the same time, drain water in its plane.   Secondary Function: Drainage Excess water is drained off the construction - not by passing through the Non-Woven Geotextile as when used for filtration - but by flowing in the plane of the geotextile leading it away from the construction. To ensure that water and/or other fluids are drained with minimum pressure loss. To ensure an ongoing drainage.

Introduction: The Jute Coir mulch mat can be used anywhere for control of weeds around a newly planted sapling. The Jute-Coir nonwoven cuts supply of sunlight to the ground and prevents growth of weeds. Being bio-degradable it decomposes over time to form humus and further helps in the plant's growth. It can absorb and retain water up to 5 times its own weight. It also absorbs and retains nutrients and fertilizers applied to the sapling. The mulch mat controls temperature of the soil below it and saves the plant from extreme heat or cold, thus increasing.   Application: Forestation projects, Plantations, Orchards requiring mulching and weed control, Sides of Runways, Factories, Railway and Container yards requiring weed control.

Introduction: Jute Geotextile is a kind of natural technical product, laid in or on soil to improve its engineering properties. Jute soil savers dissipate kinetic energy of raindrops and control surface runoff. They also help in precipitation of detached soil particles and aid in faster growth of vegetation. They absorb water up to 5 times their own weight. They degrade faster and so are used in areas conducive to growth of vegetation. They are cheap compared to coir products.   Application: Approach roads of bridges. Overburden dumps of open cast mines. Watershed and Ecology management. Slopes of Roads, Railways, Flood embankments and on hill slopes. Erosion Control in golf courses. Products Weight gm/sqm Thickness (mm) Width(m)   Jute Geotextiles can be used in the construction of temporary and access roads. They perform filtration, separation and drainage functions for 6 to 12 months and degrade without leaving any harmful residue. The inherent drainage property of natural fibres to carry water in the plane direction can be advantageously used to increase the bearing capacity of the soil by draining away water and hence stiffening the soil. Jute geotextiles are used as silt fences in short duration projects because of their filtration property. They are eco-friendly and can be disposed without any treatment or precautions. Jute geotextiles find application as night cover on waste dumps. After use they can either be disposed in the landfill or composted into a fertilizer.

Introduction: Geogrids are polymeric products formed by joining intersecting ribs. They have large open spaces known as "apertures". The directions of the ribs are referred to as machine direction (md), orientated in the direction of the manufacturing process or cross machine direction (cmd) perpendicular to the machine direction ribs. Geogrids are mainly made from polymeric materials, typically polypropylene (PP), high density polyethylene (HDPE) and polyester (PET). Geogrids are manufactured as either biaxial or uniaxial. Biaxial geogrids are those that exhibit the same strength in both the machine and cross machine directions while uniaxial geogrids exhibit the primary strength in the machine direction with minimal strength, enough to maintain the aperture structure, in the cross machine direction.   Function of Geogrid: Basic function of Geogrid is soil reinforcement. Geogrids work by interlocking with the granular or soil material placed over them.   Reinforcement: The mechanical properties of Geogrids, make them ideal for reinforcing slopes and other soil structures. To avoid collapse of vertical soil walls or steep soil slopes. To avoid rutting when dealing with poor subsoils.

Introduction: Clay soil has a low permeability and hence pore water trapped in the soil cannot come out in a short time period. Floradrain (FFD-8) prefabricated drain can be installed vertically to depths as great as 40 m. Water, under pressure in excess of hydrostatic pressure, flows through the Jute filter sheath and into the core coir channels where it is led vertically out of the soil. This may be either up or down to intersecting natural layers or to the surface where a sand drainage blanket or Jute-coir prefabricated strip drains are provided. The water in the soil has to travel the distance to the nearest drain to reach a free drainage path. The drains are usually placed in a triangular configuration of 1 to 10 metres - depending on the desired consolidation time. As a result of this method of accelerating the consolidation process, uneven post-construction settlements can be virtually eliminated.   Application: Accelerated settlement and consolidation of construction over soft soil like Road Rail embankments, underwater constructions, Foundations for tank farms and material storage areas, Land Reclamation etc.
