HDPE Uniaxial Geogrid
HDPE Uniaxial (UX) Geogrids are manufactured from select grades of high-density polyethylene (HDPE) resins that are highly oriented and are designed to resist elongation (creep) when subjected to heavy loads for long periods of time. These geogrids are also highly resistant to installation damage as well as long-term chemical or biological degradation. In fact, UX Geogrids have shown no degradation in soils with pH levels measuring as high as 12 and can be used in both dry and wet environments. Given the inert properties of HDPE resins, they can be designed for use with a variety of backfill materials, including on-site soils and recycled concrete.
Introduction:
Hdpe Uniaxial geogrid is made of high molecular polymer after extruded and laminated and punched into regular mesh before longitudinal stretching. This process makes high molecule in direct line state in oblong oval net structure with uniform distribution and high node intensity.
Features:
• High tensile strength
• Low creep deformation
• Improving bearing capacity of retaining wall or dam
• Extending the project life
• Reducing floor area
• Shortening construction period, reducing cost and maintaining expense

Application:
Enhance roadbed and effectively diffuse its load to improve its stability and bearing capacity and increase service life;
Prevent roadbed distortion and crack caused by the loss of roadbed materials;
Increase the self-supporting property of fill behind retaining wall, decrease the earth pressure of retaining wall, save cost, increase
service life and reduce maintenance expense;
