Abstract
A method is provided for repairing water retaining concrete structures, such as dams or canals. The method includes the application of a water impervious bituminous sealing layer over a selected area of the existing concrete structure to be sealed. A geotextile layer is applied over the bituminous sealing and forms a bond with this layer as well as to an outer layer of concrete. The latter protects the bituminous layer from weathering.
