OASE offers three types of waterproof pond liners: made of PVC (AlfaFol), recycled rubber (OaseFol EPDM) and natural rubber (EPDM EuroFol). PVC liners are the standard variant, while the rubber types are more elastic and resistant. Fleece under the pond liners provides protection from sharp stones and roots. The fleece should extend beyond the edge of the pond to protect the liner in the area of the capillary barrier. This prevents water loss beyond the edge of the pond. Liners and fleece are available in pre-packs for smaller ponds as well as in rolls or cut to size. Supplementary stone liners are not a replacement for pond liners, but decorative elements for the bank area.
