Belgian sandstone, better known as Belgian grès, is a high-quality sedimentary sedimentary rock with a beautiful color palette. The stone has different deposits as well as qualities. The schisty grits and the hard grits.

The schisty grès is suitable for decorative applications only. The hard gravel lends itself to facade work as well as paving. This hard grès has several varieties being the grès of the Condroz, the grès of the Meuse and the Famennian grès. This grès is especially loved for its beautiful colors. It possesses green, gray, ochre, brown and reddish nuances. When one places a whole of these stones one obtains a matchless palette of colors.
