• Did you know2021

  Portland cement — including from Buzzi Unicem USA plants — is the material that lines the inside of ductile iron and cast iron water mains to prevent iron and lead from leaching into drinking water. Cement-mortar lining (a thin layer of Portland cement applied to the pipe interior) is specified by AWWA Standard C104 as the standard corrosion protection for water distribution pipes across the United States. The same commodity Portland cement that goes into road bases and building slabs is also the material preventing lead and iron contamination in the drinking water pipes of every US city that uses cement-mortar lined iron mains. A Portland cement shortage, quality failure (contamination, incorrect chemistry), or supply disruption that compromises cement-mortar lining would affect drinking water infrastructure exactly as older lead-service-line replacements are being completed under the EPA Lead and Copper Rule Revisions — the same supply chain moment when the nation is most dependent on Portland cement for water pipe remediation.

• Concentration2023

  Buzzi Unicem's Dyckerhoff subsidiary operated major cement plants in Ukraine — the Volyn Cement Plant and Mykolayiv Cement — producing approximately 5 million tonnes per year combined before Russia's February 2022 invasion. The Mykolayiv plant is located near the southern port city of Mykolayiv, which became a front-line city in the war. Dyckerhoff Ukraine's operations were severely curtailed, and Buzzi took substantial impairment charges on its Ukrainian assets. For global building materials investors, Buzzi Unicem's Ukraine exposure was a direct illustration of how geopolitical conflict can eliminate cement production capacity from a country simultaneously needing reconstruction. Ukraine's post-war reconstruction will require enormous cement volumes — but Buzzi's own Ukrainian plants, the most logical production source, were precisely the ones disrupted by the same conflict that will eventually generate that reconstruction demand.

• Origin2024

  Buzzi Unicem's US presence is built on the ruins of some of the most historically American cement brands: Alamo Cement, founded in 1880 in San Antonio, Texas — named after the mission where Texas independence fighters made their last stand — is now owned by Italian Buzzi Unicem, which acquired it through its 2001 merger with Lone Star Industries of Wilton, Connecticut. Lone Star Industries itself had acquired multiple historic US cement brands through 1990s consolidation. The pattern of Buzzi's US acquisitions mirrors the entire US cement industry's transformation: domestic companies founded in the 19th and early 20th centuries, when American cement production was essential to building railroads, dams, and cities, were gradually absorbed into European multinationals during the 1990s-2010s as global cement companies sought US market access. The material that built American infrastructure is now primarily produced at plants owned by companies whose boards sit in Casale Monferrato, Heidelberg, and Zurich.
