PET Woven Geotextile is woven geo-fabric made from 100% polyester (PET). It is used for reinforcement of embankments.
High Strength PET Woven Geotextile is high strength woven geotextiles manufactured by weaving high tenacity polyester filament yarns into a dimensionally stable network. 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.
