SigmaRoc, a heavy side construction materials platform, completed the acquisition of Casters Beton and B-Mix Beton, two construction companies, for €13m. "The combination of B-Mix and Casters is a very attractive opportunity. Located along key waterways the combined plants will benefit from significant efficiencies. The Limburg province also remains an attractive market for concrete with Antwerp and Liege on either side. This is a significant further step in the evolution of our operations in the Benelux market," David Barrett, SigmaRoc Chairman.
