Without aggregates, our lives would be totally different. 


Aggregates are vital for building brick and stone buildings, homes, highways, driveways, sidewalks and bridges, as well as for manufacturing paint, plastics, medicines, glass, wallboard, vinyl, concrete blocks, roofing tiles, asphalt shingles and minerals for agriculture - you name it. More than two billion tons of these crucial materials are used every year in the United States alone.

Several Graymont quarries provide quality crushed stone and stone products to help meet the construction needs of their respective regions. These materials are produced to exacting standards as detailed by the appropriate specifying agency, either the state or federal Departments of Transportation (U.S.), the Ministry of Transportation (Canada), or the ASTM.

There are three distinct types of limestone, defined by their magnesium carbonate (MgCO3) concentrations. These types are Dolomitic (35 to 46% MgCO3), Magnesian (5 to 35% MgCO3) and High calcium (less than 5% MgCO3).
