Aggregates in Construction

Aggregates are vital for common construction applications including residential subdivisions, highways, driveways, parking lots, sidewalks and bridges.


Several Graymont quarries provide quality stone and crushed stone products to help meet the aggregate needs of their respective regions. These materials are produced to rigorous internal standards or external standards as detailed by the specifying agency in the region where they operate.

The product range includes coarse size fractions which can be as large as 100mm and finer graded aggregates. The exact size range available will vary depending on Graymont site. For customers that require aggregates with certain chemical properties please refer to the Products section of our website.  For specialized applications and aggregate properties please enquire with our sales team.

In some cases, Graymont can supply finer fractions of aggregates for manufacturing coatings, glass, wallboards, vinyl, concrete blocks, roofing tiles and asphalt shingles. Further information about finer products can be found under Pulverized Limestone on the Products section of our website.
