Seepage-proof geomembrane used in the underground seepage-proof project has advantages as follow. First, it has a good seepage-proof performance. Practices have proved that film seepage-proof channel can generally reduce 90% to 95% of seepage loss. Second, light, low dosage and traffic volume. Third, good adaptive deformation ability. Fourth, simple construction, short construction period. Fifth, strong corrosion resistance. Sixth, low cost.
