Tunnel surface protection Schemelsbergtunnel

Economical and Durable Surface Protection for Tunnel Inner Lining: Schemelsberg Tunnel B 39
The Schemelsberg Tunnel is part of the B 39 federal highway near Weinsberg in the district of Heilbronn, Baden-Württemberg, Germany. As a bypass, it is used by around 20,000 cars, buses, lorries and motorcycles every day and it is particularly important for commuters.

The tunnel was thoroughly modernised over its total length of 676 metres and equipped with the latest safety technology and rescue tunnels. The side walls of the tunnel inner shells – a total area of 4,500 square metres – were given surface protection with StoConcrete Protect Prime TU 100 up to a height of four metres.

The construction experts decided to use this system because it offered the following advantages: reduced expenditure for cleaning and maintenance, permanent protection of the building structure, high cost-effectiveness, reduced closure times and more safety in the tunnel.
StoConcrete Protect Prime TU 100 permanently protects the building fabric against exhaust gases and water-soluble pollutants. It is tested and approved surface protection system OS-C (OS 4). The system is highly mechanically resistant and resistant to strong chemical attack, alkalis, hydrocarbons and petrol.

Certified for excellent cleanability and low susceptibility to soiling: Top grade according to EN 11998
Thanks to its optimised surface properties, StoConcrete Protect Prime TU 100 is extremely easy to clean and is less susceptible to soiling. The water consumption per cleaning cycle is reduced. Chemical cleaning agents are not required. The bright-coloured, non-reflective surface of the tunnel system ensures greater safety. In addition, the StoPox TU 100 coating fulfils the requirements for an anti-graffiti system (AGS 1) in accordance with TL/TP-ING of the German Federal Highway Research Institute.

The StoConcrete Protect Prime TU 100 tunnel protection system reduces cleaning effort and costs in the long term, while at the same time reducing traffic-related closure times because of extended cleaning intervals. The entrance and exit areas of the Schemelsberg tunnel were coated with StoPur WV 60 due to the increased UV exposure.
