We provide comprehensive, robust solutions for water and frost protection in tunnels and caverns.

We have completed over 3,000 projects in Norway and 22 other countries in the last 30 years. Our solutions are used in water treatment plants, hydropower plants, military facilities, parking facilities, archives, and other underground halls and tunnels.

At W. Giertsen Tunnel, we understand that stable temperature and humidity protect our customers' assets and reduce life cycle costs (LCC) through reduced corrosion and operating expenses for heating and dehumidification. Thanks to our experienced installers and our own developed fabric, we can install our solutions in almost any rock chamber and tunnel with stable geology.
