In the course of the refurbishment measures started in 2011 after more than 50 years of operation, the dam and the bed of the Sylvenstein Reservoir in Bavaria were provided with a new cut-off wall (two-phase diaphragm wall) and a precise seepage water measurement system. The seepage water measurement system consists of drainage piles and a 190 m long seepage water tunnel, constructed by the company Wayss & Freytag Ingenieurbau using the microtunnelling technique. In order to minimise problems with the tunnel boring machine and hinder ingress of water into the launching cavern and the target shaft, these unpredictable zones of the rock mass had to be stabilised and waterproofed.
