US: CalPortland will celebrate its 125-year anniversary, or quasquicentennial, on 21 September 2016. The company was established in 1891 in Colton, California as the California Portland Cement company, the first cement production facility west of the Rocky Mountains. Subsequently, the cement producer provided construction materials for the expansion of Los Angeles and the south-western US. Japan’s Taiheiyo Cement purchased the company in 1990.
"Today, CalPortland is building on its past for a bright and better future. 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.
