Primary Aggregates

Primary aggregates are naturally occurring materials quarried directly from the earth, such as limestone, granite, gritstone and sandstone. Extracted from hard rock or sand and gravel deposits, they are crushed, screened and washed to meet strict engineering and grading standards for use in construction. These high-quality materials form the foundation of roads, buildings, and infrastructure projects, providing strength, durability, and reliable performance where certified compliance is essential.
