OASE AlfaFol Black 0.5mm 4x3m - Pond Liner

The OASE AlfaFol PVC pond liner is the prefabricated solution for creating ponds of any shape. Single-layer black, cold-resistant (DIN 53361), UV-resistant, and fish-friendly. Easily glueable or weldable with OASE accessories. 15-year guarantee.

💡 Expert tip: For a durable pond, lay the liner on a layer of sand or geotextile to protect it from stones and roots that could perforate it over time. Always leave a generous margin on the edges (at least 30-40 cm) before cutting: it's much easier to trim the excess than to add missing material. The weldability of AlfaFol PVC allows multiple liners to be joined for large ponds or complex shapes.
