Updating and enlarging the Paradiso Tunnel is an important component of Switzerland's transport policy – to increase the switch of international freight traffic from the road to the rails by allowing rail transit of standardized containers. To realize a four-meter corridor along the entire length of the Gotthard route, about 20 tunnels are currently being enlarged (along with alterations to platforms, traction current systems, signaling installations and overpasses) by the Swiss Federal Railways (SBB).
The main construction phase of the new, taller Paradiso Tunnel was the application of the PENETRON ADMIX-treated shotcrete proposed to the SBB engineers by IMM and Penetron Italia. Once sprayed on the tunnel wall superstructure, it prevented any water infiltration from the backfill side.
