Small Company Values. Big Company Capabilities. The Mainland Construction Materials family has been supplying a wide range of high quality construction products and relationship based construction services since 1970. Our head office, all manufacturing facilities, and supply points are located throughout the Greater Vancouver and Lower Mainland of British Columbia. Mainland Construction Materials has helped shape our local communities through road building and material supply to residential, commercial, marine, and environmental projects. We also supply high grade aggregates to concrete and asphalt plants. Together, we offer aggregates and asphalt materials, paving operations, construction services, logistics, and recycling to a wide range of projects – from small local jobs to large scale government works. By developing and growing a family of companies, Mainland Construction Materials is continually expanding our already significant capabilities and values within British Columbia.
