The OASE 57779 AlfaFol black waterproof liner is a high-quality PVC waterproofing material designed for professional water feature engineering. With a standard thickness of 0.5mm, this product ensures excellent durability and reliable sealing performance, making it ideal for custom and complex pond designs. Its 8-meter width significantly simplifies the installation process for large-area ponds or water features, reducing the need for seams and thus lowering the risk of potential leaks. The AlfaFol black material is formulated to be free of recycled materials and cadmium, ensuring safety for aquatic life (fish compatible).
A key advantage of this waterproof liner is its excellent workability; it can be easily bonded or welded using OASE's dedicated PVC accessories to create secure seams. It also boasts superior UV resistance and cold-weather performance (compliant with DIN 53361 standard), ensuring long-term structural stability and functional integrity in outdoor environments. Each roll comes with an integrated measuring tape (except for extra-large rolls) for precise cutting. This material is highly flexible and easy to handle, providing a durable and reliable water barrier for your DIY or professional water feature projects, fulfilling the basic requirements for Smart Water Control.
