Polyester geogrids (known as PET grids) are woven with high strength polymer yarns based on desired screen sizes and strengths from 20kN/m to 800kN/m (biaxial type) and 40-25kN/m to 600-400kN/m (uniaxial type).
A woven pet geogrids is formed by interweaving two or more yarns or filaments, usually at right angles.
The exterior of pet geogrid is coated with polymer or non-toxic substances, with uv resistance, acid resistance and alkali resistance characteristics, can prevent biological decomposition.
1. high intension, high tenacity, high oclusive force with soil or gravel, erosion-resistant, water drainage, light weight
2. reinforce soft soil roadbed, rib side slope of embankment, enhance isolation, inhibit ground deformation, prevent crack by reflection, increase strength of roadbed.
