The function of the geotextile geomembrane is to block the leakage channel of the earth dam with the impermeability of the plastic film, to withstand the water pressure and adapt to the deformation of the dam body with its large tensile strength and elongation, and the non-woven fabric is also a kind of polymer Short fiber chemical materials, formed by needle punching or thermal bonding, have high tensile strength and elongation.
