Norwegian tunnelling concepts focus on groundwater control through rock mass impermeabilisation using pre-grouting. This enhances the self-supporting capacity of the rock mass and creates a drained rock mass structure combined with rock support. Requirements for water control depend on the project, ranging from allowing 30 liters/minute/100m for subsea tunnels to 2-10 liters/minute/100m for urban tunnels. Benefits of the Norwegian concept include cost and time savings compared to waterproof membranes and li
