High-strength polyester geotextiles & geogrids ranging in strength from 40 kN/m to 1600 kN/m are suitable for solving complex engineering problems. They are used to reinforce soils where extremely high tensile strength with low elongation is required. TerraStop® and TerraGrid PET High Strength Woven geotextiles & geogrids are manufactured from high tenacity polyester (PET) yarns, woven to form a structured geotextile or geogrid. Manufactured under ISO 9001 QA conditions.
The design factors stated are based on manufacturer’s independent research and testing, plus industry standards. Long term product strength and stiffness are affected both by temperature and by duration of loading. Quality control (QC) tensile testing is carried out using the method given in the International Standard EN ISO10319:1996.
Key Learnings
