introduCtion 1940 to 1970 The origin of Lafarge’s involvement with Concrete Products in Western Canada can be traced to Winnipeg, where, in the late 1940’s, the Boux Brothers established a Concrete Masonry, Pipe and Precast business operating as Supercrete Ltd. Through the 1950’s, Supercrete became an industry leader in the emerging new products market utilizing prestressed concrete. Supercrete was an innovative, market-driven company and by the mid-fifties the company had expanded with new plants in Regina, SK and Fort William (now Thunder Bay), ON and offered its block, pipe and precast products over a large portion of the eastern prairies and North-Western Ontario. Meanwhile, in the late 1950’s, Lafarge Cement North America constructed a Concrete Pipe Plant, a Concrete Block Plant, a Ready Mix Concrete Plant and an Aggregates handling facility on the same property as its new Cement Plant in Richmond, BC. The ownership structure set up during the 1960’s was a form of vertical integration with Canada Cement supplying the cement and the other two owners being the largest users of Supercrete’s Ready Mix and Pipe products.

In 1974, Supercrete expanded into the Calgary Pipe and Precast markets through partnership with the owner of Stoy Concrete Products. The recession of the early 1980’s brought a slowdown for the entire construction market, but as the market returned, the Supercrete operations were strongly positioned to take advantage of new opportunities. Development of the Concrete Products Industry in Western Canada 1990 to Present In 1992, Lafarge took full control of the Calgary Precast operations. At that time, both the Calgary and Edmonton Precast operations became known as Lafarge Precast. The Winnipeg operations changed to the Lafarge Precast name in 1994. Overall, a combination of revised market strategy, management of the available resources and a very strong economy made the latter half of the 1990’s a period of exceptional performance for the Western Canada Lafarge Pipe and Precast group. Lafarge gradually assumed the leadership position for Concrete Products in Western Canada. box seCtions manhole and CatCh basin material Major plant improvements have been undertaken in the Winnipeg, Calgary, and Edmonton Pipe Plants to improve productivity and quality.
