Sweden Underground

Swedish expertise beneath the surface
Host of the World Tunnel Congress 2025

World Tunnel Congress 2025

More than a hundred years ago we were the cradle where new technologies were nurtured, the dynamite, effective machinery and production methods. Despite our relative small country we are still leading the way, building one of the most complex underground road tunnel networks, the Bypass Stockholm. A new metro with one of the deepest underground stations only accessible by elevators. And large rock caverns to store liquid hydrogen with the purpose to produce fossil free steel.

Underground Facilities

In Sweden, we have long been using sophisticated engineering techniques to build underground structures, thereby making efficient use of the resource beneath our feet. See examples below. 
In the book ”Sweden Underground” you can find more than 30 case descriptions plus a broad overview of our world-leading expertise in underground construction and rock engineering.

Geological conditions

Much of the country lies on a very hard basement of Precambrian Shield rocks, which either form the surface or are covered by a thin layer of soil.
