Vulcan Materials Company
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.[3][4] On November 16, 1998, Vulcan announced it was purchasing CalMat Company, a producer of asphalt and ready-mixed concrete based in Los Angeles, for $760 million in cash.In January 2014, Vulcan Materials announced they would be selling their Florida Rock Industry (cement and ready-mixed concrete) plants and equipment to Cementos Argos, of Colombia.[9] In January 2018, Vulcan Materials was found to be partially responsible for the Bayou Corne sinkhole, along with Occidental Petroleum and Texas Brine Company.
