Construction aggregate is the sand, gravel and crushed stone used in every residential, commercial and industrial building. It is used to build public works projects such as roads, highways, bridges, schools, hospitals, and water delivery and sewer treatment facilities. Aggregate forms the physical foundation of our infrastructure.

Aggregate is the second most consumed commodity in the world, behind water. Every Californian needs almost 7 tons of aggregate per year, a total of 544 tons in a lifetime.
