Polymer: High Density Polyethylene

Resistance to Ultra-Violet Light: A high level of resistance to UV light is given by the incorporation of 2% of weathering grade carbon black, well dispersed in the polymer. These products may be used for many years in exposed conditions.

Creep Performance:

A good creep performance under sustained loading is essential for the use of geogrids in critical structures such as walls, abutments and steep embankments.

Chemical and Biological Resistance:

Uniaxial geogrids are manufactured from high density polyethylene which is unaffected by all chemicals, including acids, alkalis and salts, normally found in soils.
