SigmaRoc said it would purchase the stake in GDH for £4.89mln using its existing resources and credit facilities, with an option to acquire the remaining 60% for £7.5mln before 31 August 2020.
The acquisition, which was expected to be “immediately earnings enhancing”, increases the group’s British operation to 11 quarries and 26 operational sites.
GDH also expands the company’s South Wales operation, which was started in late-2018 when it acquired the Foelfach quarry in Carmarthenshire.
“With GDH as part of the group, we will operate nearly a dozen quarries, 100mln tonnes of reserves and resources, close to 500 people employed, with significant skill, drive and enthusiasm within the various management teams", said Max Vermorken, SigmaRoc’s chief executive.

In particular, Tim's knowledge and network within the industry will benefit SigmaRoc's growth in the aggregates and construction materials market in the UK,” the company said.
