Hydroelectric Power Plants
Specificity of Hydroelectric Power Plant working environment consisting of permanent and extreme influence of water medium was the reason for establishment of independent working group within CHESTREAL PROGRESS, a.s. company. This group is focused to identification and comprehensive solution of problems coming out from the Hydroelectric Power Plant operation, especially in the area of hydro-insulations, redevelopment, reshaping and anti-cavitation, anti-abrasive and anti-fouling coatings.
