Welcome to the www.akta-ev.de.

On the following pages you will find the most important information of the task force "Arbeitskreis Tunnelabdichtung e.V." about the waterproofing of underground structures with especially geomembranes.

Modern traffic tunnels are increasingly planned for a functional service life of more than 100 years. For this reason they must be protected extensively against the effects of groundwater and water penetrating through rock fissures. The construction and sealing specifications are correspondingly strict, especially with respect to the required service life.

Secure sealing of underground buildings, tunnels, reservoirs, and more

• the protection of these buildings
• the functionality
• the long-term usability

Through a required quality manufactured Sealing System is our goal.
