It takes 400 tons of aggregates to construct the average modern home. Aggregates are present from the concrete in the foundation all the way up to the shingles on the roof—and everywhere in between, like the wallboard, tile, glass and plaster.

The use of aggregates is not limited to the home, itself. Stone, sand and gravel go into the production of household products such as cleansers, cosmetics, toothpaste and chewing gum.

The Cities We Work In

Aggregates make our cities possible.  We use aggregates to build cities with structures so tall we call them skyscrapers.  Aggregates line the tunnels of our subways and are used to make our sidewalks.

We light up our cities with hydroelectric dams like the Hoover Dam, built with 4.5 million cubic yards of aggregates.
