1.Product Description
Woven geotextiles are manufactured by extruding and slitting a polypropylene film, then weaving these individual yarns to form the fabric. They are characterised by high tensile strengths at low elongation (high tensile modulus), and are designed for separation, stabilisation and reinforcement applications.
2.Product Feature
High tensile strength and low elongation provides dimensional stability
Requires less aggregate, reducing the overall thickness of the road
Increases performance life of the road
Withstands tough construction loading
Resistant to ultraviolet degradation
Resistant to biological clogging, making it ideal for leachate collection systems and filtration beneath hard armor system
Ease of installation reduces time and labor costs
