%X Les g¨¦omembranes, g¨¦n¨¦ralement associ¨¦es ¨¤ d¡¯autres g¨¦osynth¨¦tiques, constituent l¡¯¨¦tanch¨¦it¨¦ principale de presque trois cents barrages ¨¤ travers le monde. Illustr¨¦ par des exemples d'utilisation dans les diff¨¦rents types de barrages, en construction et en cours de r¨¦habilitation, cet article nous renseigne sur les performances d'¨¦tanch¨¦it¨¦ et la durabilit¨¦ des g¨¦omembranes dans les conditions d¡¯utilisation s¨¦v¨¨res propres aux barrages. In almost 300 dams worldwide, geomembranes are the main waterproofing component. The geomembrane is generally associated with other geosynthetics performing various functions. In this paper, uses of geomembranes in the various types of dams are reviewed. The types of dams reviewed include: embankment dams (earth and rockfill dams), concrete and masonry dams, and roller-compacted concrete (RCC) dams. Design and construction aspects are considered, as well as selection of geomembranes and performance (including seepage control and durability). The paper is illustrated using examples of new dams and rehabilitation of existing dams.
