What is Polyester Geogrid?
Paragraph :
Polyester Geogrid is a high-strength, woven geosynthetic material designed for soil and structural reinforcement. Made from high-modulus polyester yarns and coated with PVC or bitumen, it provides exceptional tensile strength, low creep, and long-term durability. TYNOD polyester geogrids are widely used in road foundations, slope stabilization, retaining walls, and railway subgrades, ensuring structural reliability and performance even under extreme conditions.
