The Industry

Although most of us are unaware of it, aggregate products play an integral part in our everyday lives. Aggregate is a major ingredient in the manufacture of both asphalt and concrete.  The asphalt used to construct our driveways, roads and highways, and the concrete used to build our sidewalks, bridges and buildings, is dependent on the supply of quality aggregate.

In addition to the more obvious uses, aggregate is also used in the manufacture of many other items including paint, paper, plastics, glass, and agricultural, medical and household products.
