Cut Rubble Stone (Condroz Sandstone)

Designation:

Condroz sandstone, hard sandstone, Condroz psammite, Meuse sandstone, Famennian sandstone.

Origin:

Belgium, Provinces of Liège and Namur: the valleys of the Amblève, Bocq, Hoyoux, Ourthe and Samson.

Description:

Slightly micaceous clayey sandstone, fine-grained, of Upper Famennian stratigraphic age (Upper Devonian, Paleozoic).

Appearance:

Sandstone deposits come in an extremely varied range, with brighter shades (yellow, green, red, brown-rust) or more muted tones (from green-grey to blue-grey, wine-red, ochre, beige). The stone develops a patina, turning rust-brown when it is rich in iron, and in blue-grey or greenish tones when it is rich in feldspars. While the visible face of the rubble stone will always be split (natural), some sides may have a sawn surface.

Shades may vary depending on how the deposit is quarried.

Applications:

Sandstones are ideally suited to producing all types of rubble stone, steps, wall copings, corner stones, mould heads, facing stones, for both exterior and interior use. With a split surface, the rubble stone is then dressed to give it its final finish: rough, cut back, re-cut or squared. Naturally non-slip, sandstone is also recommended for ground surfacing: pavers, platines, slabs, edging.

Tolerance applicable from the limits of the nominal dimension ranges (min. and max.): 1 cm
