Expand your horizons and learn from your peers with this unique tour of two NSSGA member locations. With a special focus on transporting aggregates, you’ll visit CEMEX’s Navigation facility, where aggregates are brought in by rail, and Vulcan Materials Company’s Houston Yard, where material arrives by ship through Houston’s shipping channel.

Please wear closed-toe shoes. NSSGA will provide hard hats, safety glasses, and safety vests.


Vulcan Materials Company Houston Ship Yard

The Vulcan Materials Company Houston Ship Yard is an aggregates distribution operation located at the Houston Ship Channel in Houston, Texas. The distribution yard has been providing high-quality construction materials to the greater Houston market for over 29 years. Construction aggregates are delivered to the shipyard by Panamax-class self-unloading vessels from Vulcan’s Calica Quarry located in the Yucatan Peninsula of Mexico. 

Houston-based Vulica Shipping, a subsidiary of Vulcan Materials, operates three Panamax ships specifically designed to service this unique supply chain of high-quality construction materials from Mexico to the United States. The Houston Ship Yard is a key outlet for the limestone products manufactured at Vulcan’s Calica Quarry.


CEMEX Navigation Aggregates Distribution Yard

The CEMEX Navigation Aggregates Distribution Yard is located about three miles east of downtown Houston along the banks of Buffalo Bayou and upstream from the Houston Ship Channel. The aggregates distribution yard has been providing high-quality construction materials to the greater Houston market for over 25 years. 

Construction aggregates are delivered to the CEMEX Navigation Yard by train from the CEMEX Balcones Quarry, located in New Braunfels, Texas, which is located about 175 miles west of Houston. The CEMEX Balcones Quarry is recognized by the U.S. Geological Survey as the nation’s top producing crushed stone quarry. The Houston area is a key market for the crushed and washed limestone produced at the CEMEX Balcones Quarry. The limestone transported to the CEMEX Navigation Yard is distributed to internal and external customers for the greater Houston construction market.   

CEMEX also manufacturers ready-mix concrete at this site and operates a barge loading facility as needed for transporting construction aggregates. CEMEX is a global building materials company with the U.S. Headquarters located in Houston, Texas.
