Grey sandstone with fine and compact grain. In addition to the characteristic light grey colour, it presents some dark grey and veined variations. The material has a homogeneous and uniform colour with a small percentage of veined material. Rust colour caused by oxidation may be present on the external part of the slab or processed product. This is a rock without cavities or micro fissures. It is made up of fragments of carbonate rocks, silicate rocks, quartz and mica. Thanks to the presence of carbonate rock, it can be classified as CALCARENITE. The physical-mechanical characteristics allow it to be classified as very compact stone (specific weight 2650kg/m3) with low absorption (0.95%); it is frost resistant and easy to process.
