Modern tunnels are planned with a functional service life of more than 100 years. They must be properly protected against the impact of groundwater. Therefore, there are high demands on the structure and on the waterproofing. Hence, it is very important to supply a perfectly compatible waterproofing system.

In principle, there are distinctions made in tunnel construction between a sealing against water pressure and against seepage water. For seeping water, a Carbofol® tunnel geomembrane that is 2 mm thick can be used as an umbrella seal. For occurring hydrostatic water, the use of an all-around sealing (360°) with a separation system is the required solution. This results in three different sealing systems.
