SOSA GERA SA in Zernez has been operating a state-of-the-art gravel processing plant since 1985, which meets both the economic and environmental requirements of the time and allows us to supply the entire region with quality products. In addition to concrete and asphalt, round or crushed gravel is an important product that we rely on every day. The right materials are produced at the gravel plant for forest paths, retaining walls, sewage pipes and snow-covered roads.

With the large fleet of our sister company Terretaz SA  we guarantee fast and reliable delivery of building materials to every construction site in the Engadin.

We would like to thank all our customers and business partners for the trust they have placed in us and look forward to continuing our successful collaboration!

Nothing works for us without sand and gravel

The extraction and processing of sand and gravel is our passion, and we want trade and industry to benefit from this.

Processing gravel means producing a high-quality construction material from one of the few raw materials that nature offers us in Switzerland.
