Tensar International’s TriAx geogrid has been used at one of the stadiums hosting the 2010 World Cup
It is being used at the 68,000-seat Green Point stadium in Cape Town. The stadium is set into a deep excavation; however, initial problems were encountered as a result of the excavated material being placed over surrounding spaces without being compacted. When temporary haul roads for access were built over these areas, considerable ground movement was experienced. The contractor built a mechanically stabilised road base with two layers of TriAx geogrid and 400mm of aggregate.
