TRIGRID¢çKR/WR are manufactured by polymer resin coating after knitting/weaving with high strength and low elongation industrial polyester yarns. They provide high long-term design strengths (LTDS) and excellent soil interaction.
Also, TRIGRID¢ç is recognized as excellent product worldwide which had passed Geosynthetic Certification Institute's Product Certification Program(GCI-PCP) that is enforced by Geosynthetic Institute(GSI)in American.
