In 1975, Rigo Collavino co-founded Prestressed Systems Inc. (PSI) in Windsor, Ontario. The company’s initial focus was on the manufacture and installation of hollowcore floor and roof slabs for the Ontario and Michigan (sold under Hollowcore Inc.) construction markets

International Precast Solutions, LLC (IPS) was formed in June 2008 when PSI, through its U.S. Holding company, purchased the operating assets of an existing precast operation in River Rouge, Michigan. The formation of IPS provided PSI with the capacity and ability to produce architectural precast components. It also gave PSI additional structural precast production capacity and a major manufacturing plant located on the U.S. side of the border. The two companies can now bid complete precast structures by combining products and cross-marketing each other’s products.

Over the years a strong and dedicated management team has been instrumental in growing these two companies, into a full-service structural & architectural precast operation known as The Prestressed Group.

The Prestressed Group is an award-winning North American leader in precast concrete structures and systems. TPG has drawn on over 40 years of experience to provide superior concrete solutions which translates into continuously exceeding customers' expectations and contributes to exceptional industry standards. We pride ourselves as a leader in the manufacturing and installation of prestressed concrete products. We serve the North American construction market with customized precast solutions, seamless delivery and personalized service.
