1. Carbon black inhibits attack by UV light. Determined in accordance with BS 2782:Part 4:Method 452B:1993. Any section of grid fully exposed to sunlight can be expected to retain 90% of its quality control strength for periods in excess of 40 years in temperate climates and 20 years in tropical climates.
2. Determined in accordance with GRI Test Method GG2-87, and expressed as a % of the quality control strength.
3. ULS determined as a lower bound using standard extrapolation techniques to creep rupture data obtained following the test procedure in BS EN ISO 13431:1999 for 120 year design life.
4. In-soil temperature.
5. Tensar RE500 geogrids are inert to all chemicals naturally found in soils and have no solvents at ambient temperature. They are not susceptible to hydrolysis and are resistant to aqueous solutions of salts, acids and alkalis (pH 2.0 to 12.5) and are non- biodegradable.
6. Partial factors should be applied to derive the safe design strength (Pdes ) typically given in the form : Pdes = Pc /(fm x fd x fe x LF)
7. Tensar RE500 geogrids are stiff monolithic geogrids with integral junctions and are manufactured in accordance with Quality and Environmental Management Systems which comply with the requirements of BS EN ISO 9001:2008 and BS EN ISO 14001:2004 respectively
8. All quoted dimensions and values are typical unless stated otherwise.
