In 1970, mining engineer Dr Rudolf Amberg founded the Hagerbach Test Gallery as a research and development facility for tunnel construction.
The focus was initially on testing drill and explosives technology: between 1974 and 1976, the blasting facility and blasting chamber were built, the firing gallery and the observation bunker were constructed, and a second access point was created to allow operation with circulating air.
1979 the marks the date for the opening of the canteen and the beginning of our gastronomy activities, a business that has not stopped growing since then.
In the 1980s, a shooting range was constructed for the investigation of mechanical properties on artillery.
The opening of the building materials test laboratory in 1984 was a significant change of course with respect to the services offered at VSH.
Our independence and expertise is continuously under review and has been confirmed by accreditation from SAS since 1994.
The following years saw the construction of a concrete plant to assist with concrete injection tests (1995) and the development of special education and training courses to expand our range of services with respect to tunnel safety.
Today our activities cover a broad range and mix of services including excavation and development, sealing and installations, operational aspects such as safety & security. Prototyping for the sensible future use of the underground is present and will be a focus in the years to come. These days our well-established building material test laboratory is branching out to new locations to service the market. In addition, our Restaurant inside the mountain, banqueting services, guided tours, group activities and events of all kinds round off our offerings.
