Since 1987, Vulcan Materials has shipped crushed limestone throughout the Gulf from its 5,900-acre mine in Calica, Mexico, on the Yucatan Peninsula.

Unique to Vulcan’s operation is a proprietary harbor constructed adjacent to its mine, just south of Playa del Carmen. The harbor is connected to the mine by a five kilometer-long high speed 60-inch-wide conveyor system, moving up to 12 million tons annually of various grades of limestone, fines and related products to waiting ships. Vulcan operates three of its own Panama-max sized vessels to transport products to eager markets, in a completely vertically integrated operation.

At the Port of Brownsville, Vulcan imports about 700,000 short tons of crushed limestone annually, consumed by regional construction industries, where it is used for road and general construction industries, where it is used for road and general construction projects in support of the Rio Grande Valley’s accelerating growth.

Since it began mining operations in Calica, Vulcan has maintained a leadership role to protect both the environment and Mexico’s archeological heritage. Mining operations have responsibly protected archeological remains of the ancient Maya on Vulcan’s properties, while working to preserve and restore Mayan ruins discovered while planning excavation activities. Vulcan’s preservation efforts are focused on ruins dating back to 2100 B.C. and are performed in association with the Mexican National Institute of Archeological History.
