What is Aggregate?
Aggregate refers to sand, rocks, gravel, crushed stone, shale, and any rock product mined from the ground. These materials play a crucial role in various construction projects, from building roads and schools to hospitals and water treatment plants. Much like oil or gas, aggregates are a non-renewable natural resource that demands protection and respect.


Aggregate and Your Community
More than 80% of concrete, 90% of asphalt, and 100% of glass is made from aggregates. Additionally, a special type of sand is produced by aggregate companies for frac operations in oil exploration. Aggregates are also needed for cosmetics, toothpaste, and many other applications.
Per capita, each Albertan utilizes 10-15 tonnes of aggregate annually, equivalent to a full truckload.

Why Access to Aggregates is Important
Aggregates are non-renewable, and once land is developed over it, access to aggregate is permanently lost. If local aggregate resources are not available, the cost of hauling aggregates from distant sites increases. Every kilometer of travel adds $0.10/tonne to gravel costs, along with heightened vehicle emissions and wear on roads.
