Filament woven geotextile fabric
Polyester Woven Multifilament Geotextile are high strength woven geotextiles manufactured by weaving high tenacity polyester filament yarns into a dimensionally stable network.
Woven filament geotextiles for soli reinforcement are manufactured from select high tenacity polyester yarns with molecular weight > 25000 and carboxyl end groups < 30.The products have excellent chemical and biological resistance and assured durability for long-term applications.
The inherent characteristics of polyester - high tensile strength and modulus, low elongation, low creep and high long-term design strength - makes these products ideal for soil reinforcement applications.The fabric develops excellent frictional interaction with a wide variety of soils and granular materials.
The relatively small openings of these fabrics enable them to act as efficient separators preventing the mixing of costly granular materials with fine-grained soils.The geotextile has reasonably high permeability to prevent excessive build-up of pore-pressures due to applied loadings.
Applications
· Subgrade stabilization
· Area stabilization
· Basal reinforcement of embankments on poor ground
· Working platforms & Load transfer platforms
· Reinforced soil slopes and walls
