FIELD: hydraulic engineering. SUBSTANCE: method includes filling of blockweights, protective layers and placing of mineral fibrous plates into body of impervious shield in several layers. Plates are laid so as to ensure reliable overlapping both horizontal and vertical joints. After erection of hydraulic structure and beginning of filling of water storage reservoir, porous spaces of mineral fibrous plates are filled with suspended particles of filtering flow with formation of shielding layer in plates on the side of upstream face. EFFECT: provided possibility for formation of impervious device in any climatic zones with use of local building materials. 3 dwg
