Highway, metro and railway tunnels, and underground structures (e.g. for power plants in caverns, car parks, basements, storage areas) must be protected from water infiltration, which can create humidity and induce damage to electrical systems, spalling of concrete, formation of ice stalactites, etc.

Benefits of a SIBELON^® geomembrane system:

• Provides watertightness;
• Prevents damage to electical and electronical services;
• Creates a barrier to infiltration of gases or hazardous chemicals from the sorrounding ground;
• When combined with a drainage system, controls the negative effects of pressure on the structure.
