Tunnel waterproofing is an essential process to prevent water infiltration that may compromise structural stability and functionality. To achieve this, various methods and materials are used, including geosynthetics, waterproof geomembranes, and drainage systems.
These elements are strategically installed between the surrounding ground and the tunnel lining to protect the structure against groundwater pressure. Proper waterproofing not only extends the service life of tunnels but also enhances operational safety and significantly reduces long-term maintenance costs.
