| Tunnelling and mine-gallery construction has a long tradition at Walo Bertschinger. For more than 50 years we have been engaged in underground construction projects of all sizes and degrees of complexity, using every kind of construction technique.
We are a reliable partner for all underground infrastructural works including road and rail systems, supply and disposal of water, waste water and power, for the construction of new facilities as well as the renewal or repair of existing underground structures.
WALO is your expert partner:
- for driving in hard rock by blasting or using tunnel-boring machines or part-face heading machines
- for driving in unconsolidated deposits using shield drivers or machine-assisted construction with additional measures to shore up loose deposits
- in normal to very difficult geological conditions
We combine our experience and versatility with our technical expertise in a focused effort to ensure that your projects are completed on time, within budget and to the highest quality standards.
