Construction aggregates (crushed stone, sand and gravel) are the foundation of the nation’s infrastructure. Knife River’s aggregate operations provide a local source of high-quality materials to support private and public construction projects.
Whether it’s high-spec aggregates for highways, bridges or airport runways – or if it’s sand for the sandbox, all your projects are important. We have an aggregate solution for any need.
With our large trucking fleet and talented drivers, we also are able to deliver rock wherever you need it, whenever you need it.
