PET Uniaxial Geogrid
Geogrids are used for high strength applications such as retaining wall and embankment reinforcement.
Geogrids are open structures composed of pre-stressed, high strength bars, with excellent long term creep strengths. There are several different types of geogrids. Polyester (PET) type geogrids are made from a woven matrix of high tenacity polyester fibres that are coated with a protective polymer coating. The polyester fibres are oriented in one principle strength direction. Geogrid strengths can be very high, with design values of up to possible 200 kN/m (13,500 lbs per ft). The strength of a geogrid allows positive reinforcement of embankments, steep slopes, retaining walls and other vertical soil structures. Geogrids interlock with the soil providing long term reinforcement and are the most cost-effective method of creating additional horizontal space. Polyester geogrids have excellent long term creep performance.
