The Carrières du Hainaut, a solid partnership

For more than 135 years, Carrières du Hainaut has been extracting this unique and authentic stone from the Belgian ground. Its incomparable quality has earned it worldwide acclaim. By encouraging their teams’ skills and knowledge and constantly improving their tools, the company has become Europe’s largest ornamental limestone quarry.


Our stone

From nature. From here.

Blue Limestone of Hainaut, from the Belgian subsoil, is a natural, authentic material whose origins dates back 350 million years, when our regions were submerged by a tropical sea.

Blue stone is a durable product par excellence: It is easy to maintain, solid, durable and timeless, and further enhanced with the patina of time. It does not deteriorate and retains its properties and charm. It is exceptionally long-lasting. Only the most beautiful stones deserve your attention. At Carrières du Hainaut the selection procedures are strict, rigorous and uncompromising. This outstanding quality label is your best guarantee.


(Eco)-responsible production

Blue stone is the result of a long extraction and transformation process, which is carried out at a single site in Soignies, Belgium. This is unique in the large-volume sector (200,000 cubic metre/year) and is aimed at reducing as much as possible our production’s ecological footprint. Carrières du Hainaut is committed to offering a natural stone and an outstanding quality service, in respect of the environment. Their working methods ensure responsible handling, where safety is paramount.

What we stand for


A high quality product

As with all noble materials, meticulous work is required to fully reveal the mineral. No stone without cutting, no cutting without selection. Carrières du Hainaut craft their products following rigorous selection of the material. Each stone has been carefully chosen, worked and finished to enhance your interior, exterior or façade. Only stones that have successfully passed the very selective sorting procedures deserve the Carrières du Hainaut quality label.


A craft in the rules of art

Blue Limestone of Hainaut also symbolises age-old know-how that guarantees quality and perpetuation of local employment. The blue limestone sector is a very specific one. Carrières du Hainaut relies heavily on the unique know-how and expertise of their teams and distribution network. By participating in the ‘Centre de Formation aux Métiers de la Pierre’ (CEFOMEPI - training centre), Carrières du Hainaut make sure their personnel undergo continuous training and ensuring the sustainability of the craftsmanship.


A local and natural stone with low environmental impact
