A new stadium with recycled aggregates for the city of Guelph

13 May 2014

Since 2012, the city of Guelph in Ontario (Canada) has a completely refurbished college stadium. An ultra modern facility, it can accommodate major sporting and cultural events and so contribute to the attractiveness of the city. It is also a model of sustainable construction through the use of Aggneo™, LafargeHolcim’s recycled aggregates!


Guelph, a 115,000 inhabitant-city in south-western Ontario, approximately 100 km from Toronto, is famous for its university, one of the best in Canada, including its curricula in Veterinary Medicine and Agronomy.

The college stadium (Alumni Stadium), built in 1970, underwent a major renovation in 2012:

  • On the Canadian football field (slightly different from American football), natural grass was replaced by a synthetic lawn.
  • A new eight-lane race track was added and a new stand has added 7,500 seats to the existing 7,600 and new dressing rooms.
  • In addition, an efficient lighting now allows organizing events at night.
  • A two-storey building, adjacent to the new entrance, houses reception venues and conference rooms.

LafargeHolcim’s recycled aggregates for a more sustainable stadium

LafargeHolcim has been present from one end to the other on the worksite, providing a range of solutions for a more "sustainable" stadium:

  • the sublayer of the race track was built in recycled aggregates Aggneo™, whose qualities and performance are similar to those of natural aggregates and are widely recognized in Ontario.
  • the chamber supporting the large electronic scoreboard, Chronolia® was chosen for its high mechanical strength.

An important asset for the university and the city, the renovated Alumni Stadium will host major sporting and cultural events to attract many spectators in Guelph, especially to create a meeting place for the community.
