September 19, 2016, Glendora, CA,  – CalPortland is proud to announce and celebrate its 125 Year Anniversary on September 21, 2016. The company was established in 1891 in Colton, CA as California Portland Cement Company, the first cement production facility west of the Rocky Mountains. Strategically placed to provide construction materials for the expansion of Los Angeles and the southwestern United States, the founders built this company on the values of Integrity, Quality Unsurpassed, Safety and Technical Superiority.

Through key strategic mergers and acquisitions we have brought together more technology and the best people and now proudly serve six western states and two Canadian provinces. CalPortland is dedicated to using all of our resources to help make our customers successful,” said Allen Hamblen, President and CEO of CalPortland.

CalPortland takes pride in building upon and maximizing the efficiencies and strengths of a vertically integrated organization. Through key components of cement manufacturing and distribution, aggregate production, ready-mixed concrete operations, asphalt production and construction services the company provides sustainable and resilient products for the construction and reconstruction of the country’s infrastructure.
