The acquisition includes major aggregate operations with annual sales volumes of about 2 million tonnes, reserves and resources of about 170 million tonnes, and four ready-mixed concrete plants selling about 0.3 million m3 in the Greater Seattle area. Both parties agreed not to disclose the purchase price.
Dominik von Achten, chairman of the managing board at HeidelbergCement, said: “The acquisition of the Corliss operations is a great strategic fit with our already strong presence in cement, aggregates, and ready-mixed concrete in the Pacific Northwest.
"The transaction significantly enhances our vertically integrated position in one of the fastest growing US markets."
Steve Corliss, president of Corliss Resources, said: “For more than five generations, the Corliss family has proudly served our customers with high-quality building materials and contributed to the growth and development of our communities."
HeidelbergCement says that the Greater Seattle area is a prospering and sustainability focused market within the growing state of Washington, supported by transportation infrastructure under development and further boosted by the recent Federal Infrastructure package.
It adds that the combined Corliss and Lehigh Hanson business is ideally positioned to capture this growth potential and provide a wide range of sustainable, low carbon products to the customers in the area.
Corliss has 230 employees and around US$80m of revenue.
HeidelbergCement says the transaction is another important milestone in the ongoing portfolio optimisation programme as part of its strategy ‘Beyond 2020’. During 2021 the company acquired assets in Canada, Australia, Italy, and Tanzania and divested businesses in Greece, Kuwait, Sierra Leone, Spain, and the US West Coast.
