Abstract
A method and arrangement for vertically sealing off dumps to prevent the seepage of water therefrom. A sealing wall is produced around the dump area which is to be sealed off. The sealing wall has at least one drainage sheet which extends over the length of the sealing wall, and is embedded therein. The drainage sheet produces a hydraulic gradient relative to the surroundings, as a result of which the seepage water collects in the drainage sheet. The occurrence and the quantity of the seepage water accumulated in the drainage sheet is determined in a controlled manner, and is withdrawn from the sealing wall.
