Geo textiles are permeable nonwoven fabrics used to separate, filter, reinforce, protect, or drain. Geo textiles allow filtration/separation of granular layers in roads and rail applications, used to protect membranes in landfill applications, used in coastal defence applications and used in Landscaping to protect surfaces and structures from weeds and root growth.
They are made from high quality pp fibres. It is non-woven Geo textile needle punched to form a strong fabric that relates its dimensional stability adding years to the life of any road railway land fill , horticulture & civil environmental application.
Application of Geo-textile:-
- Embankment of soft Ground
- Shallow foundations
- Railway Tracks
- Confinements ponds, Rivers, Reservoirs
- Canals & river shores.
Its applications includes
- Road construction, highways and highway embankments.
- Airport runways.
- Shore protection in reclamation works.
- Asphalt repaving of roads.
- Coastal and riverbank revetment systems.
- Protection for geomembrane in landfills.
- Geobags manufacturing.
- Soil erosion control.
As a Separator used between unsuitable material and good bag filled material, this usage will reduce the excavation depth of unsuitable sub-grade. It reduces the aggregate thickness to stabilize the sub-grade. The Non-woven geotextile fabric maintains a uniform settlement of the sub-grade and hence improves the sub grade strength and prolong the life of the system.
As a Filtration polypropylene geotextiles have different range of pore openings to reduce the potential of clogging. The range of pore openings shall be compared to the grain size of the material to be filtered to obtain the optimum filtration.
Non-woven geotextiles not only acts as a filter and a separator but also reduces the maintenance of erosion control systems and costs.
Besides providing high puncture resistance, it also provides lateral in-plane drainage for the system. It effectively filters fine slit soils that are subjected to turbulent flow. Hence maintaining and enhancing the stability of erosion protection structures.
As reinforcement non-woven geotextiles’ function involves stabilization of a soil mass by provision of tensile strength fabric system.
Drainage is related to the role of filtration and is a function of the permeability of a geotextile and its pore opening size or photometry. Water is conveyed along the plane of the non-woven Geotextile due to its construction and then to an outlet. Water may be vertically or horizontally conveyed.
