Winter break and holidays


During winter months, depending on the weather, Alfredo Polti SA will temporarily interrupt its production. From mid-December 2018 to the beginning/mid-February 2019 the quarry and laboratories will remain closed. For this reason we kindly ask you to send us all urgent orders as soon as possible.

Splitting Machine Menhir 1300 x 600GT

This hydraulic splitting machine  joined Alfredo Polti SA during the month of August. This machine is mainly used for the production of masonry articles of various sizes, allowing us to offer our customers products without visible machining holes. Until now this was only possible on small-medium-sized wall stones, while now it is also possible on large-format blocks. We are convinced that this new investment will help us further improve the quality of our products.
