Project: Neuer Kaiser Wilhelm Tunnel, Cochem, Deutschland
Investor: Alpine Bau, Dortmund, Deutschland
Works: contact injection of Euras mortar (injection)
State of the structure: reinforced concrete precast tunnel construction, occurrence of water leakage at joints of precast elements.
The process of restoration: application of Euras mortar (injection) in the areas of increased water flow. Injection is performed using the existing equipment by adding Euras Gel into mortar which functions on hydraulic basis. Existing water is effectively and permanently eliminated from the contact zone. Lining of the injection equipment didn't have openings for water drained from tunnel lining joints and excavated rock profiles. It was not mounted on said project, or on the next Karslruhe tunnel project.
