Les pierres siliceuses

S’il est fréquemment utilisé en pavés ou couverture de sol pour ses qualités antidérapantes, le grès du Condroz n’en demeure pas moins le matériau de référence dans l’habitat traditionnel de nos régions.

L’arkose combine une grande dureté et une grande diversité de couleurs variées, dans une gamme pastel (rose, gris, etc) ou plus soutenue (brun, etc).

Le quartzite est, sauf exceptions, destiné à des applications à l’extérieur. Les grains de quartz liés par de la silice qui le constituent en font une pierre extrêmement résistante.

Le grès schisteux est une pierre typique des Ardennes et de la région de Malmédy dont l’aspect varie en fonction de sa composition propre et dont la gamme de couleurs se décline selon une palette de gris, gris-bleu, brun ou rouille.

Les schistes se prêtent en extérieur aux produits de maçonnerie et surtout pour les aménagements de jardin mais fournissent également des produits de sol. Ils trouvent également des applications à l’intérieur, en éléments sciés de différentes finitions.

Why Walloon stone?

Because it blends in with the landscape and environment, lending itself to both modern and traditional architecture, because it plays its part in enhancing our cities and green spaces, because it has contributed to the quality of our lives over the centuries, natural stone has long been associated with a sense of comfort and well-being.

The Walloon Region, naturally rich in stone, has become a true centre of excellence. Today, thanks to its 15 varieties of fine quality stone, and to remarkable technological developments, the ornamental stone sector can offer you a wide range of products for any application.

Stone masonry in our country is synonymous with age-old know-how. Its continued use is the final seal of approval for any building material and all our stones have successfully stood the test of centuries. When people choose Walloon stone, they contribute to preserving local jobs. Our quarries are close to their customers who take direct advantage of the first-rate services provided by the entire sector. There is also a matter of trust and traceability. There are few middlemen and it is easy for people to find a deposit where the character and qualities of the stone are known by experience. Stone is intuitively termed an ecological material. The major ecological asset of our stones is that the stages between its actual extraction and its application are short and cause little pollution, i.e. on the whole, stone consumes little energy and releases few harmful emissions, such as CO2, for example. A series of other heritage value criteria obviously come into consideration as, of course, the harmonious integration of new construction into the built environment.
