Heidelberg Materials acquire Walan Specialty Construction Products
Company grows business and bolsters low-carbon product portfolio with acquisition in Delaware
HEIDELBERG Materials North America has entered into a binding purchase agreement to acquire Walan Specialty Construction Products in Delaware. The transaction comprises a state-of-the-art vertical mill slag grinding plant built three years ago with an annual capacity of 150,000 tonnes, located in proximity of the Port of Wilmington.
Slag cement, produced from by-products of steel manufacturing, enhances the strength and durability of concrete while lowering its environmental footprint. It can be used to replace some of the conventional cement in a concrete mix, and its production requires far less energy and natural resources than conventional cement. The use of slag cement and other supplementary cementitious materials (SCMs) is a key part of Heidelberg Materials’ decarbonisation strategy.
‘Heidelberg Materials’ investment in the Walan slag business reflects our ongoing efforts to expand our portfolio of low-carbon products and drive sustainable and commercial value for our customers,’ said Chris Ward, member of the managing board of Heidelberg Materials and responsible for North America. ‘It is also the latest example of our focus on optimizing our positions in core markets through our disciplined pure-play growth strategy.’
The acquisition of Walan Specialty Construction Products further enhances Heidelberg Materials’ low-carbon cementitious portfolio in North America’s north-east region and extends the company’s reach in this dynamic and growing market.
Both parties have agreed not to disclose the financial terms of the transaction.
