Introduction

PET Geogrids are a woven biaxially oriented or uniaxially oriented geogrid,made of high tenacity polyester yarns with PVC coating.It has open meshes with square apertures produced by a weaving process,continuous polyester filaments yarns are into a mesh and then impregnated to give them a protective polymer coating.PET Geogrid tensile strength from 20/20kN/m-1000/1000kN/m(Biaxial type) and 30/20kN/m-1000/50kN/m(Uniaxial type).The high strength PET geogrid which is polymer-coated to protect against UV radiation and installation damage,provides reliable long-term reinforcement for base courses.

Advantages Of PET Geogrids

*PET geogrid are durable,resistant to seismic and dynamic loads,reliable and cost-effective

*High resistance against earthquake forces,flexible integrity and aesthetic appearance

*Increase bearing capacity in all soil conditions

*Cost savings due to lower base material requirement

*Limit creep effect

*High Tensile Strength in low elongation

*Easy and fast installation

*Optimal grid opening size

*Wide ranging applications

Application Of PET Geogrids 

*Base reinforcement and subgrade improvement

PET geogrids reinforce base course in roadways,providing shear resistance and improving the road system’s elastic modulus

*Reinforced steep slopes and retaining walls

Bearing capacity of PET geogrids enables the construction of steeper,safer slopes and retaining walls to optimize land use and reduce land disturbance in infrastructurel

*Separation

PET geogrids prevent differing aggregate particles from migrating and mixing under loads.This enhances the long-term performance and integrity of a construction
