Sosa gera SA

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

With the large fleet of vehicles belonging to 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 cooperation!

Nothing works without sand and gravel

The extraction and processing of sand and gravel are our passion, and we want trade and industry to benefit from this. Processing gravel means turning one of the few raw materials that nature offers us in Switzerland into a high-quality building material.
