Polypropylene Geogrid

IMPTREX Geogrids are stiff monolithic geogrids with integral junctions. They are oriented in two directions such that the resulting ribs have a high degree of molecular orientation which continues through the area of the integral node. The ribs have a rectangular cross section with square edges.

IMPTREX Geogrids are used for the reinforcement of soils and aggregates in construction of structures such as road pavements, working platforms and reinforced foundations.

  • Carbon black inhibits attack by UV Light. Determined in accordance with BS 2782: Part 4: Method 452B:1993
  • Determined in accordance with BS EN ISO 10319:1996 and as a lower 95% confidence limit in accordance with ISO 2602:1980 (BS 2846:Part 2:1981)
  • Determined in accordance with GRI Test Method GG2-87 and expressed as a % of the quality control strength
  • Imptrex 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 to salts, acids and alkalis and are non-biodegradable.
  • Imptrex Geogrids are manufactured in accordance with a Quality Management System which complies with the requirements of BS EN ISO 9001:2000. All quoted dimensions and values are typical unless stated otherwise.
