Trevi Spa has 6 different teams working on the Drammen Cut&Cover Tunnel Project

At this stage of the works for the Drammen-Kobbervikdalen high-speed line project, Trevi Spa has 6 different teams working.

Each is equipped with a pre-drilling rig and a jet grouting rig and they are carrying out the treatment in the «full-face» and «mixed-face» areas. In some areas we are about to start inclined jet grouting, which is essential to consolidate the soil beneath the houses still present on site.
