The purpose and aim

Our goal is on the one hand the development and the use of safe construction methods and techniques forwaterproofing of underground structures, tunnels, reservoirs, and others.
On the other hand the protection of these buildings, the functioning and the long-term usability.
With an high quality installed waterproofing system we will achieve this goal.

The task force for tunnel waterproofing systems ("Arbeitskreis Tunnelabdichtung e.V." AK TA) was established in March 2001 and is the union of professional Companies, which use geomembranes for waterpoofing of tunnel buildings.
