360° view of the gutter at the Klimahaus in Bremerhaven.
Every year, half a million international visitors to the Klimahaus Bremerhaven learn about the Earth’s various climate zones. How extreme weather conditions can affect a building’s envelope became an unintended issue for the operator of this scientific exhibition center: The salty North Sea air had compromised the functionality of the roof membrane. As a result, water seeped in through the surrounding aluminum-lined gutter and into the insulation, causing damage even in the exhibition halls.
The building owner, Bremerhavener Entwicklungsgesellschaft Alter-/Neuer Hafen mbH & Co. KG (BEAN for short), therefore commissioned DADEGO Dachdecker-Genossenschaft Bremen eG to immediately repair the walkable gutter. The requirement was for a weather-resistant product that adheres to the metal substrate and provides long-term protection for the building structure. The building owner, the installer, and liquid polymer manufacturer Triflex consulted on a suitable solution and determined that the fabric-reinforced waterproofing system Triflex ProDetail met the specified requirements.

Requirements for the Renovation
- Reliable protection against moisture ingress
- Rapid restoration (within a few hours)
- Seamless and joint-free waterproofing, even for complex shapes and details
- Highly resistant to chemical, mechanical, and thermal influences
- Application to an existing substrate without demolition
- Elastic material
- Processing can be done in sections
