Waterproof Geotextile

product presentation

Waterproof Geotextile is a kind of geotextile waterproofing material composed of plastic film as the anti-seepage substrate and non-woven fabric. Its anti-seepage performance mainly depends on the anti-seepage performance of plastic film.

Currently, the primary plastic films used for anti-seepage applications both domestically and internationally are polyvinyl chloride (PVC) and polyethylene (PE). These materials are highly flexible, lightweight, and have excellent elongation, deformation tolerance, corrosion resistance, low-temperature tolerance, and frost resistance. The key mechanism is that the impermeability of these plastic films effectively blocks water leakage pathways in earth dams, while their high tensile strength and elongation enable them to withstand water pressure and adapt to dam deformation. Non-woven fabric, another high molecular short fiber material, is formed through needle punching or thermal bonding. It has high tensile strength and elongation. When combined with plastic films, it not only enhances the tensile strength and puncture resistance of the plastic films but also increases the friction coefficient of the contact surface due to its rough surface, which helps stabilize the composite geotextile membrane and protective layer. Additionally, these materials exhibit good resistance to bacterial and chemical erosion, making them resistant to acids, alkalis, and salts.
