Trigrid® EX geogrid is produced from high strength polyester yarns, which have excellent durability and creep behaviour in civil engineering applications. In contrast, traditional polypropylene geogrids are characteristically affected by creep to a much greater extent.
Trigrid’s polyester fibres are coated in a polyolefin, which provides protection from installation damage common to polypropylene geogrids. Installation damage can lead to tensile strengths lower than those stated before installation. The Trigrid® EX polypropylene coating also provides an excellent defence against chemical attack and other external threats. Its resilience is a major advantage over other products which may lose up to 60% of their ultimate strength during construction.
