Products and services
Our aggregates divisions operate as Dufferin Aggregates in Ontario and Demix Agrégats in Quebec. Our 10 quarries and 15 sand and gravel pits supply products used to form the bases of highways, roads and sidewalks, as well as to build sewers and water mains, and to manufacture concrete and asphalt products. In total, our aggregates divisions produce more than 18 million tonnes per year of crushed stone, gravel and sand for the commercial, industrial, residential and civil engineering sector.
Our high quality products are a result of the technical expertise of our employees, backed by a rigorous quality assurance process which ensures the production of consistent quality aggregates, in accordance with required standards and specifications.
