Introduction

Polyester Biaxial Geogrids are high strength materials developed for bidirectional geogrid requirements for various applications of civil engineering.The material is manufactured by weaving polyester yarns in the rectangular form and coating the same with PVC.High performance rating is assured by virtue of the seaming method specially designed for more robust nodules.Polyester Biaxial Geogrids can be produced with different mesh sizes and tensile strength range from 20kN/m-1000kN/m,width of  polyester geogrids is from 1 to 5.2m,you can customize it according to your project needs.

Properties Of Polyester Biaxial Geogrids

*High modulus of elasticity,ideal for soil reinforcement

*High chemical and weathering resistance

*Low creep to ensure a service life over 100 years

*Integrates perfectly into environment friendly reinforcement systems

*Tensile strength range 20kN/m to 1000kN/m

*High resistance to UV radiation

 Application Of Polyester Biaxial Geogrids 

*Provide higher bearing capacity for the runway,apron and taxiway foundations at the airports

*As reinforcements for highway expansion projects

*Soil improvement works intended for reducing the quantities of  ballast and sub-ballast and preventing potential settlements at railway applications to be performed on poor bearing soil

*Improve the load bearing capacity and preventing local settlements for the foundations against the heavy loads at the foundations of container storage yards and industry structures
