Martin Marietta Materials has acquired two Colorado-based companies, growing its workforce by about 400 people, strengthening its long-term position in the state's southern market and complementing its already substantial presence in the metro Denver area, according to the company.
The larger of the two acquisitions, Colorado Springs-based Rocky Mountain Materials & Asphalt and Rocky Mountain Premix, was finalized on Feb. 6.
It adds nearly 400 employees at a granite and limestone quarry (Red Canyon Quarry), two active sand and gravel operations (Sokol and Penrose Ranch), two ready mix plants, two asphalt plants and a recycling facility. The business also sells decorative landscape rock and other landscaping materials.
The smaller acquisition, that of Front Range Aggregates and its Rock and Rail subsidiary, was completed on Nov. 13.
It adds approximately 25 employees at an aggregates facility (Parkdale Quarry), a distribution facility (Drennan Yard) and Rock & Rail, a federally chartered short-line railroad that operates east and west between Pueblo and Parkdale, Colo.
Combined, the acquisitions add nearly 1 billion tons of aggregates to Martin Marietta's reserves. The new employees and locations join the company’s Rocky Mountain Division, based in Westminster, Colo., just north of Denver.
