Martin Marietta Materials is a leader in high quality cement, ready-mixed concrete, asphalt and aggregates made of crushed stone, sand and gravel, all of which are used in industrial, agricultural and environmental construction. Based in Raleigh, North Carolina, the firm runs operations in 26 states, Canada and the Bahamas, where it has a state-of-the-art aggregates plant and ship-loading facility.

Formed in 1993 as a subsidiary of Martin Marietta Corporation, the firm spun off and became an independent company in 1996 with a mission to innovate the materials that build solid foundations in communities. In the industry, the company ranks No. 1 or 2 for aggregates in 90 percent of the regional markets in the US and has the largest dolomitic lime operation in the country. It is the largest producer of strategic cement in Texas, the leader in ready-mixed concrete in Texas and Colorado, and the premier asphalt paver of highways along the Colorado Front Range. Today the firm is experiencing emerging demand trends not seen in over a decade, estimating recently that the majority of US population and economic growth through 2050 will occur in 11 megaregions: the Northeast, Florida, the Piedmont Atlantic (consisting of inland Georgia and the Carolinas), the Texas Triangle, the Arizona Sun Corridor, the Colorado Front Range, sections of Northern California and Southern California, and the Cascadia region of Washington.

The company sees preventive maintenance as key to innovating its processes for the future. Other priorities are focusing on the careers of its 9,000+ employees and advancing sustainability practices companywide. Earlier this year the firm was recognized for its reclamation work in Ohio, where it converted a retired open-pit limestone quarry into an 86-acre natural open space for the community, including a 30-acre lake stocked with fish.
