What does the anti-seepage function of filament geotextile depend on

   It is well known that the filament geotextile has the functions of filtering, isolation, reinforcement and protection, high tensile strength, good permeability, high temperature resistance, freezing resistance, aging resistance, and corrosion resistance. It is a permeable geosynthetic material made of synthetic fibers through needle punching or weaving. So what does the anti-seepage function of filament geotextile depend on?

   Filament geotextiles use plastic film as an impermeable substrate, and its impermeability mainly depends on the impermeability of the plastic film. At present, the plastic films used in anti-seepage applications at home and abroad mainly include polyvinyl chloride and polyethylene. They are a kind of polymer chemical flexible materials with small specific gravity, strong extensibility and high adaptability to deformation.
