Following the Group taking-over of all LafargeHolcim’s production installations located at CDH in April 2021, shortly followed by the acquisitions of the B-Mix and Casters businesses in Belgium, SigmaRoc created the Granulats du Hainaut aggregates brand and separated its European heavy-side materials operations into two separate platforms. CDH continued as a Europe wide dimension stone platform and a new, integrated, concrete and construction aggregates Benelux platform was created, including the GduH, Stone Holdings, B-Mix and Casters businesses.

The Benelux platform produces over 2 million tonnes of aggregates and over 250,000m³ of concrete, servicing the Hainaut, Liege and Limburg Market. Our aggregate products supply a range of partners and construction companies with products for concrete, sea defence work and riverbank fortification.
