Porphyry coarse tiles and wall facing

Sheared coarse tiles are used to pave surfaces with a steep slope, because they have the maximum roughness possible for paving, thus offering greater adherence on the transit of vehicles. In fact, the coarse tile leaves the gap exposed. The lateral faces have a natural surface with thickness varying from 3 to 10 cm. They are laid side by side. The depth varies from 4 to 12 cm. This material is often used for garage access ramps, but also to face columns. It is also used to face walls and wainscoting.
