J. Hulla, D. Chlapik, R. Hok

All Slovak dams that are included in the ICOLD register were constructed in geological conditions of the Carpathian flysh except of one that was built in a volcanic rock. Their subsoils were treated by grouting curtains. This paper describes water pressure tests as unsuitable tests for determining of grout curtain effectiveness, construction conditions on dams, testing problems and results of monitoring. Determining the effectiveness of the grout curtain based on the groundwater level changes, uplift conditions, filtration velocities and developments of seepage during the operations of the reservoirs.
