Vulcan Materials Company is an American company based in Birmingham, Alabama. It is principally engaged in the production, distribution and sale of construction materials. Vulcan is the largest producer of construction materials, primarily gravel, crushed stone, and sand, and employs approximately 7,000 people at over 300 facilities. Vulcan serves 20 states, the District of Columbia and Mexico. Vulcan's innovative Crescent Market project led to construction of a large quarry and deep water seaport on the Yucatán Peninsula of Mexico, just south of Cancun. This quarry supplies Tampa, New Orleans, Houston, and Brownsville, Texas, as well as other Gulf coast seaports, with crushed limestone via large 62,000-ton self-discharging ships.
In the late 1980s Vulcan acquired Reed Crushed Stone, near Kentucky.
On June 7, 2005, Vulcan completed the sale of its chemicals business, known as Vulcan Chemicals, to Occidental Chemical Corporation. The sale of assets included Vulcan's chloralkali plants in Wichita, Kansas; Geismar, Louisiana; and Port Edwards, Wisconsin, as well as Vulcan Chemicals' joint venture located in Geismar, Louisiana. In 2005, Vulcan acquired 11 aggregates operations and five asphalt plants in Arizona, Georgia, Indiana and Tennessee.
On February 19, 2007, Vulcan announced that it would buy stone and cement producer Florida Rock Industries for $4.7 billion. Vulcan completed the acquisition of Florida Rock on November 16, 2007.
