The acquisition of two Colorado operators has positioned Martin Marietta to grow its Front Range stone, sand & gravel, concrete and asphalt production workforce by about 400 and strengthen a long-term stake in the state’s southern market— owing to a gain of nearly 1 billion tons of aggregate reserves accompanying the deals.

The larger of two transactions was finalized in early February, netting Colorado Springs’ Rocky Mountain Materials & Asphalt and Rocky Mountain Premix. The flagship business spans the Red Canyon granite and limestone quarry; Sokol and Penrose Ranch sand & gravel operations; plus, two asphalt plants and a recycling facility. Rocky Mountain Premix runs two central mixed plants in Colorado Springs.

The Rocky Mountain Materials and Premix deals follow by three months Martin Marietta’s acquisition of Front Range Aggregates and its Rock & Rail subsidiary, encompassing an aggregates and distribution facility (Parkdale Quarry and Drennan Yard), plus a federally chartered short-line railroad that operates between Pueblo and Parkdale, Colo. All of the acquired businesses join Martin Marietta’s Rocky Mountain Division, based north of Denver in Westminster, Colo. Strong in aggregate, ready mixed and asphalt production, the division emerged from a major asset swap Martin Marietta and Lafarge North America effected in 2011.
