About 100 km west of Vienna, the Danube flows through the Wachau valley, which remains undeveloped. The river regularly bursts its banks and floods into the adjacent localities, reaching up to the first floor of  the  buildings. After the  devastating damage caused in  Weißenkirchen in 2002, the decision was made to install a flood protection wall. Bauer constructed the  underground  section, a Mixed-in-Place wall up to 10 m deep with adjusted supports. The anchor plates for the mobile protective barrier were integrated into the top bars, which are constructed as required by local authorities. During the June flood in 2013, the protection system put on an impressive display of  its effectiveness.
