Tunnel structures exist out of concrete segments. The interconnecting joints are sealed with various sealing profiles, which is especially the case in water crossing tunnels. Obviously, these seals need to be protected from fire.
In the German Elb tunnel, Promat conducted special fire tests in order to prove the fire resistance of the PROMATECT® -H solution as shown below.

Also in the case of an immersed tunnel building system, the complex joint structure needs to be safeguarded from fire. A lot of experience has been acquired in the Dutch tunnel building industry, while using PROMATECT® -H as a protective lining for both the concrete and the joints.
