We currently hold in concession two active natural stone quarries: one is situated at 'Seccarezze' and has been used for over thirty years to extract blocks of large dimensions, used for slab sawing with multi-blade frames; the second natural stone quarry, situated at 'Crivella Superiore' and in our concession since 1927, produces raw blocks of high quality, with slightly different physical and mechanical characteristics. To preserve the quality of the extracted natural stone, diamond wire cutting and expanding mortar are used instead of explosives.
