Polyester / Polypropylene Woven Geotextile is interwoven by high tenacity PET / PP filament yarn into a dimensionally stable network
The inherent characteristics of Polyester / Polypropylene high tensile strength and modulus, low elongation, low creep and high longterm design strength makes the good ideal for soil reinforcement application. The fabric develops excellent frictional interaction with a wide variety of soil and granular materials.
The relatively low openings of these fabrics enable them to act as efficient separators preventing the mixing of costly granular materials with finegrained soils. It has reasonably high permeability to prevent excessive buildup of pore pressures due to applied loadings.
