What Alfredo Polti SA does
Alfredo Polti SA is a third-generation, family-owned natural stone quarrying and processing company headquartered in Arvigo, in the Canton of Graubünden, Switzerland. The company has operated the Calanca Valley quarry since 1920 and currently employs co-directors Vania Polti Ambrosini (Administrative Direction) and Giovanni Polti (Technical Direction), supported by a workforce of approximately 30 staff across quarrying, production, sales, and administration. Its sole raw material is Calanca Gneiss, a metamorphic rock formed over 300 million years ago and uplifted with the Alps 65 million years ago, extracted across an 11.5-hectare site with daily capacity of 140 tonnes and reported 100% material utilization.
The core technology stack is mechanical and geological rather than digital: extraction followed by surface treatments including natural split (exploiting the stone's 1-3mm schistosity), diamond sawing, sandblasting/flaming, bush-hammering, and polishing. The quarry is monitored by a radar system installed in 2020 in partnership with SUPSI. Finished stone is delivered to construction and landscaping applications including roofing (piode), facades, interior and exterior flooring, stairs, walls, masonry, pools and ponds, kitchens, bathrooms, fireplaces, window sills, and thresholds. Reference projects include the Kloster Einsiedeln monastery restoration and the Radisson Blu Andermatt hotel.
Alfredo Polti generates revenue through three streams: (1) one-time B2B sales of raw and processed stone via direct project sales and a network of 14 specialized natural stone retailers (Fachhändler) across Switzerland, supported by a B2B Fachhändler Portal; (2) one-time DTC sales of finished consumer products — vases, candle holders, espresso cups, wine coolers, serving plates, ice rocks, key fobs, and a 2024 book publication — through the Gneis Shop e-commerce storefront priced from CHF 10 to CHF 600; and (3) custom fabrication and project-based stone commissions for architectural and landscaping work. The company holds ISO and SGS certifications and is a member of the Swiss Natural Stone Association (NVS), Pro Naturstein, and the Safety Charter; it received the Giardina Gold Award in 2023.
