Using geomembrane for canal seepage control, has been widely used in water conservancy projects. Through the construction of the Dakou Project on the west bank of the Yarkant River, the principle of channeling seepage control structure, the selection of composite geomembrane and anti-seepage construction technology, technical requirements, laying and seaming construction and quality control are discussed. Practice has proved that achieved good anti-seepage effect.
