Polyester Geogrid (PET Geogrid)
Product Description
Polyester Geogrid is a high-strength geosynthetic material made from high-tenacity polyester (PET) yarns. The yarns are woven or knitted into a stable grid structure and coated with PVC or bitumen to enhance durability and chemical resistance.
It is mainly used for soil reinforcement, retaining wall construction, and road base stabilization. The product provides excellent tensile strength, low elongation, and long-term performance under harsh environmental conditions.
Properties of polyester geogrids:
• Tensile strength: Thousands of tests have been conducted, and the results for tensile strength are typically from 85 MPa to over 200 MPa, depending on the design and manufacturing of a different polyester geogrid. we has tensile strengths up to 800 kN, and are truly exceptional and ensure reliable service under the most difficult conditions.
• Modulus of elasticity: The modulus of elasticity for polyester geogrids will lie between 2.76 and 4.14 GPa, which enables it to deform elastically without permanent damage under any level of stress.
• Creep resistance: Polyester geogrids are designed to be resistant to creep, which is a time-dependent deformation caused by constant load. Accelerated creep tests show that these geogrids will retain their structural integrity over very long periods and are thus suitable for use in long-term applications in civil engineering.
• Chemical resistance: Generally, polyester is a material which has excellent resistance to a wide range of chemicals, thus improving the durability of geogrids under hostile circumstances, such as one finds in landfill applications and road construction.
• UV resistance: A protective polymer coating is treated on many polyester geogrids to enhance its resistance to ultraviolet radiation for its longevity under sunlight.
Applications
Polyester Geogrid is widely used in geotechnical, transportation, and environmental projects, including:
Road and highway base reinforcement
Railway subgrade and embankment stabilization
Retaining wall and steep slope reinforcement
Soft soil improvement and erosion control
Mining and landfill foundation reinforcement
