Slabs (Belgian Sandstone)

Designation:

Condroz sandstone; hard sandstone; Condroz psammite; Meuse sandstone; Famennian sandstone.

Origin:

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

Description:

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

Appearance:

Sandstone deposits occur 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 that turns rust-brown when it is rich in iron, and blue-grey or greenish tones when it is rich in feldspars. While the visible face of the paver will always be split (natural), 2 of the 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 slip-resistant, sandstone is also recommended for ground surfacing: pavers, platines, slabs, edging.
