About River Rock

It was an exciting day for the Mitchell family, owners of Seven M Construction Ltd, on May 1, 2000. They incorporated River Rock into their family of construction subsidiaries. When River Rock opened, only one topsoil pit and one screener were functioning. Today there are several topsoil sites, as well as the recently opened Galloway Gravel Pit and Laja Sand Pit. Since 1982, Seven M has proudly upheld their thirty year tradition of excellence in paving, landscaping and other forms of construction, and in the fall of 2011, they hope to continue this tradition with the opening of the Perrier Gravel Pit.
