Tunnels

Due to their location, tunnel structures are constantly exposed to groundwater and sewage water, as well as to dissolved chemical elements and compounds. In these circumstances, the aim is not only to provide a good waterproofing, but also to relieve the hydraulic and static load caused by water accumulating in the ground by intercepting it and then draining it away. The use of ISO-DRAIN drainage geocomposites in the waterproofing of the tunnel vault and walls allows a stable drainage of water from the rock to the soil into drainage channels
