Gruner to open a new branch in Sion in March 2025

From March 2025, Gruner will also be managing infrastructure, environmental, geotechnical and civil engineering projects from Sion.

Gruner is delighted to announce the forthcoming opening of its new branch in Sion, scheduled for March 2025. Located in the heart of central Valais, in the recently built Cour de Gare district, this geographical expansion will enable Gruner to reinforce its support of local clients.

The team will be dedicated to supporting projects in the fields of infrastructure, water management, the environment, geotechnics and engineering structures. Thanks to this new location, Gruner will be able to offer tailor-made solutions adapted to the specific challenges of the region, while maintaining direct and effective contact with its customers. Together with the existing site in Martigny, Gruner will have a total of more than 30 employees in Valais.

This opening symbolises Gruner's ongoing commitment to getting closer to its customers and partners throughout Switzerland, by offering innovative and sustainable services. The official opening of the branch in the first half of 2025 will be an opportunity to present our team and our plans. For more information and contact details, please visit our Sion location page.
