The buy-and-build construction materials group bought an initial 40% stake in South Wales quarrying group GD Harries & Sons last year.
This morning the firm announced it had secured the remaining stake in the business, which was founded in 1977 by Gerald D Harries then a haulage and plant hire operator.
His son Ian Harries will continue to have an active involvement in the company going forward
GDH operates 17 production facilities, including seven hardstone quarries, six concrete plants, three asphalt plants and a wharf operation, as well as four road contracting units.
With 240 staff, GDH supplies most labour and materials in-house to control costs and quality
GDH has close to 80m tonnes of reserves and resources or close to 100 years supply at the present consumption rates.
Max Vermorken, CEO of SigmaRoc, said: “Over the past 18 months we have assisted GDH with its development as a minority shareholder.
“As we are moving into a new phase of the development of the business we look forward to continue to work with Ian Harries and his team to build and strengthen GDH as a member of the SigmaRoc Group.”
