Rock Stress Measurements • Drill Tools • Rock Support
The Norwegian landscape and topography create both challenges and opportunities that made knowledge of tunnel construction a prerequisite for the development of energy sources and the construction of modern infrastructure.
- 1,800 roads and railway tunnels.
- 200 underground power stations.
- 5,000 km of hydropower tunnels including access tunnels.
- 300 rock caverns for treatment and storage of water, sewage, oil, gas etc.
- Various defense facilities incorporating underground caverns and tunnels.
Stantroll’s products and services are based on the Norwegian method of tunnell design, excavation and rock support.
Rock mass investigation and advisory
