History
BOAGLIO LUIGI STONE OF LUSERNA
The company was founded in 1982 under the guidance of my father Boaglio Mario, since 2006 the management of the company has passed into my hands and subsequently, since 2012, my son has also joined the company to guarantee and pass on the experience and mastery in the future.
We currently own two quarries that allow us to follow the process from extraction to processing in our laboratory and subsequent distribution of the product, allowing us to guarantee quality and 360° knowledge of the product.
As the years go by and technologies and processing methods evolve, we are constantly updating ourselves, but always keeping an eye on the past and on the tradition handed down from generation to generation.
In recent years, to ensure an ever-increasing choice of processes and products, we have moved our laboratory and first warehouse to a new location with 14,000 m2 of space, while maintaining the old location as an additional warehouse for the blocks extracted from our quarries.
The Luserna stone
Luserna Stone has been used as a building material since ancient times, even as a masonry element. Since the 17th century, Luserna Stone has had noble uses such as the external flooring of the royal palaces of Turin, Racconigi and Venaria Reale.
Another very important use is the roofing for the Mole Antonelliana in Turin, strongly desired by the architect Alessandro Antonelli, made entirely of slabs, furthermore slabs were inserted into the structure between the courses of bricks in order to give greater solidity to the building which, at the time of its construction, was the tallest masonry construction in the world.
