Glacier Northwest - A CalPortland Company


About Us

The Longview ready mixed concrete plant achieved the Environmental Protection Agency’s (EPA’s) ENERGY STAR Challenge for Industry in 2018. This facility worked diligently to reduce its energy intensity by dramatically exceeding the minimum energy reduction requirement of 10% established by the program. By doing so, this plant is helping to clean-up our environment by reducing greenhouse gas emissions caused by energy consumption. CalPortland has produced and distributed the highest quality building materials in the Western United States and Canada since being established in 1891. These products are used all around us as the foundation of our society providing the roads and highways, airports, buildings, dams and levees, homes, and the required infrastructure to support social development.

The CalPortland name stands for integrity, quality, and technical superiority and is evident in every load of product that we deliver.
