Vulcan is North America’s leading producer of construction aggregates, primarily crushed stone, sand and gravel.
We produce these materials from natural deposits such as granite, limestone and trap rock. Our quarrying process typically begins with drilling and blasting the rock into smaller pieces. Next, the material goes through various stages of crushing and screening to produce the sizes and specifications desired by our customers.
Construction aggregates form the underpinnings of our cities, towns and transportation networks. Thousands of years ago, civilizations built entire cities with stone, sand and gravel, and many of these ancient structures exist today.
Our construction aggregates are used in a number of ways.
