|Project||Leak detection in a tunnel construction|
|Location||2008 - Limerick, Ireland|
A road tunnel below the river Shannon in Limerick, Ireland, was constructed between 2006 and 2010 by an international consortium, with STRABAG as the prime contractor.
TEXPLOR was authorized to investigate the cause of the water inflow. The target of the investigation was to examine the water-tightness of the combi walls and the underwater bottom plate.
The following possible causes were to be investigated:
The sensors were lowered into the water onto the surface of the concrete surface, and tracers were induced in several wells outside the sealing system. Furthermore, various joints were investigated using the single sensor EFT®. The measurement results were described and displayed in a comprehensive report.
