Vulcan Materials Company

Vulcan Materials Company is the nation's leading producer of construction aggregates, primarily crushed stone, sand, and gravel. The company serves the construction industry through three primary business segments: Aggregates, Asphalt Mix, and Ready-Mixed Concrete. Vulcan's aggregates are essential materials used in virtually all types of public and private construction projects, including highways, airports, buildings, and infrastructure development.

Headquartered in Birmingham, Alabama, Vulcan operates a geographically diverse network of over 300 production facilities across the United States. The company has strategically expanded its operations through targeted acquisitions, including US Concrete (2021), CalMat (1998), and Shamrock Materials (2017), strengthening its position in ready-mixed concrete and regional aggregates markets.

Vulcan Materials Company was founded in 1956 as Vulcan Corporation, initially focusing on the production and distribution of construction aggregates. The company grew organically through the 1960s and 1970s, establishing operations across multiple states and building a reputation for quality materials and reliable service.

In the 1980s and 1990s, Vulcan expanded through strategic acquisitions, including the acquisition of Reed Crushed Stone in the late 1980s. The company's major expansion into ready-mixed concrete began with the acquisition of CalMat Company in November 1998 for $760 million, a significant move that diversified Vulcan's product portfolio beyond aggregates.

In 2005, Vulcan divested its chemicals business (Vulcan Chemicals) to Occidental Chemical Corporation, allowing the company to focus on core construction materials operations. The company continued strategic acquisitions throughout the 2000s and 2010s, including the acquisition of Shamrock Materials in 2017 and Aggregates USA in 2017.

In June 2021, Vulcan completed its acquisition of US Concrete (USCR) for $1.3 billion, significantly expanding its ready-mixed concrete operations and market presence. More recently, in 2024, Vulcan acquired Wake Stone and Superior Ready Mix, further strengthening its aggregates and concrete operations.
