Waterproofing B-40 Tunnel

Project Information: The work consists of installing two layers of material (Geotextile + PVC) that will act as a physical barrier between the natural terrain and the structure in order to prevent water leakage and ensure correct sealing, thus avoiding the negative effects resulting from water accessing the structure. In total, nearly 80,000m2 of waterproofing will be installed.
