Lehigh Cement Company began as a single-mill operation in Ormrod, Pennsylvania, producing Portland cement. As the demand for concrete increased in the early 1900’s, the company thrived. Over the years, a strategy of acquisitions, modernization and increased productivity propelled the company to the position of one of North America’s leading providers of cement and construction materials.

It rapidly grew by acquisition and became a multinational concern with interests in chemicals, construction, energy, tobacco and other industries. Over the years, Hanson shifted its focus to construction materials and sold its non-core business. By 2006 Hanson had become the world’s largest producer of aggregates.
