Polymer: Polypropylene

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

Chemical and Biological Resistance:

PERMAGRID biaxial geogrids are manufactured from polypropylene which is unaffected by all chemicals, including acids, alkalis and salts, normally found in soils. Also, it is not a nutrient, therefore these products are not affected by micro-organisms in the soil.
