Fire Protection in the Gotthard base tunnel Section Bodio

To ensure that the tunnel walls are protected in the case of a fire, they have been treated with special fire protection mortar because temperatures exceeding around 300 degree Celsius lead to the concrete crumbling, and when concrete is exposed to temperatures above 1,000 degree Celsius it loses its load-bearing capacity altogether and the tunnel collapses. The MEYCO® Fireshield 1350 fire protection mortar manufactured by BASF protects the concrete used for the tunnel tube in the Bodio section near the southern entrance to the tunnel against excessive heat.
"Being covered with a layer of fire protection mortar the tunnel walls withstand temperatures of up to 1,400 degree Celsius for a minimum of 90 minutes. This way we gain some precious time for firefighting," says Frank Clement, BASF expert for underground fire protection solutions.
