Overview
The Gina gasket and Omega seal are used between the sectional elements of immersed tunnels to prevent water ingress due to external water pressure. This combination of high water pressure seals not only allows for sealing but also for the transfer of the hydrostatic loads and movements between the tunnel ends due to soil settlement, creep of concrete, temperature effects and if required earthquakes
Gina Gasket EPD
Our Gina Gaskets with verified EPDs for three popular variants (Shore 40A, 50A, and 60A) have been supplied to landmark infrastructure projects like the Fehmarnbelt tunnel between Denmark and Germany, the world's longest immersed tunnel. This demonstrates how our commitment to environmental transparency integrates with delivering proven performance in critical infrastructure projects.
