SigmaRoc joint venture with Carrières du Boulonnais

Carrières du Boulonnais

Carrières du Boulonnais to assist in development and expansion of Granulats du Hainaut

AIM-quoted construction materials group SigmaRoc have signed a joint-venture agreement with major Calais-based high-grade limestone and construction materials company Carrières du Boulonnais, who have become 25% shareholders in SigmaRoc Group’s Granulats du Hainaut business, with the aim of expanding it into a Benelux and northern France-wide supplier of limestone products.

As a shareholder, Carrières du Boulonnais will assist in the development of Granulats du Hainaut from a financial and technical perspective, and materially increase their market presence in the target markets. Granulats du Hainaut is the SigmaRoc Group’s Benelux production and distribution subsidiary and SigmaRoc will continue to wholly own its quarrying assets in Belgium.


As part of the joint-venture agreement, Carrières du Boulonnais have agreed to co-fund the new crushing and screening installations planned to be built by 2024 at Granulats du Hainaut’s aggregates operations, Carrières du Hainaut. The French firm will also lend its extensive technical expertise in the sector to optimally set up the new installations and product offerings.

As a result, Granulats du Hainaut will be able to commence servicing the Benelux and northern French markets and, following the expiry of their existing agreement to supply LafargeHolcim in 2024, will be able to deliver more than two million tonnes of virgin construction aggregates per year, making them one of the largest suppliers in the region.
