Above the weir at Bad Abbach in Lower Bavaria, a canal branches off from the Danube to a large lock for commercial shipping. Seepage discharges were detected at the dam of the lock canal in the event of flooding.

Remediation of the dam was carried out with a Mixed- in-Place cut-off wall; jet grouting was used for realizing the connections to the existing pumping station.
