The present-day production facilities are in Tui, in the heart of the geographical area where one of the most traditional types of stone in our autonomous community, pipeclay, is extracted. At present, COIGRASA has 20,000 m2 of premises, of which almost 4,000 m2 are warehouses which can hold a total of 18 stone-processing machines, most of them the most up-to-date models which, together with highly qualified workers, allow any type of stone product to be made, no matter how complicated it may seem.
