Researchers from the AdMaS Center, led by prof. Kudrna together with prof. Šťastník, diagnosed the sealing shell of the tank at Dlouhé Stráně on June 3, 2019. This tank serves as part of the Dlouhé Stráně pumped-storage hydro power plant. The tank shell is made up of asphalt layers and there are present faults on the shell surface.
On that day, the entire tank was drained and it was possible to get to the bottom itself. A visual inspection of the current condition was carried out on site and the locations of the core drilling sites to be investigated were indicated. This event was part of the project of the Technology Agency of the Czech Republic TH04020154 entitled: “Optimization of construction, repairs and operation of asphalt-concrete sealing shells”.
