The company Alfredo Polti SA is a typical family business, as it often is in the natural stone industry in the south of Switzerland. Our secret is our strong foundation. For more than 100 years we have been living the tradition of craftsmanship in the Calanca Valley, yet our way of working and our philosophy are anything but outdated.

We are committed to continuity. This is reflected in the constant quality of the material, but also in our company history. The long-standing collaboration of our team creates trust, because we can pass on experience and values and offer our customers know-how as well as a reliable and personal service.

Chisel, stone, paper

Sustainable success is no coincidence, but a conscious decision. That is why the respectful use of resources and the production of meaningful products are at the center of our activities. In order to keep the balance between supply and demand, we always plan our work with the quarried quantity.

With our commitment, we get the ball rolling, and with ISO certification, we put the commitment on paper. Regular investments in further training and infrastructure are a must for us, because this keeps us competitive and at the same time honors the image of natural stone.
