A certain hydropower station is a concrete face rockfill dam, with the dam height of 219 m. Because of various reasons, Composite geomembrane was added on the concrete face below the elevation of 382 m. A combined impermeable system composed of composite geomememes and concrete panels is formed. This paper introduces the impermeable scheme of composite geomemmembrane, the impermeable silo design, the design of cross joint, the laying and fixing of geomemmembrane and the sealing and welding of geomemmembrane as well as its quality control and quality test and so on. The above achievements have accumulated experience for the application of composite geomememes in the anti-seepage technology of high dam.
