Pond liner Oase Damfilm 4 m x 3 m (12 m²) – Oase 50647

The Oase Damfilm pond liner measures 4 m x 3 m and covers 12 m², providing a flexible, waterproof membrane for garden ponds and water features. Made to serve as a watertight barrier, this liner retains water while protecting surrounding soil and substructure. Its dimensions suit small to medium installations and repairs and allow installation under gravel, sand or decorative finishes to create a durable pond base.

Advantages

The liner is flexible and conformable to uneven ground, reducing the need for extensive excavation. The material resists common environmental stresses encountered in garden applications and provides a continuous, seamless barrier when correctly installed. Its size offers an immediately usable sheet for typical backyard ponds without the need for on-site welding or joining for small installations. Lightweight and easy to handle, it simplifies transport and placement compared with rigid alternatives.

Suitable for

• Lining small ornamental and wildlife ponds

How to use

Prepare the pond excavation by removing sharp stones, roots and debris; level and compact the base and, where appropriate, add a protective underlay or sand bed to prevent punctures. Unfold the liner and position it so that it overlaps the pond edges sufficiently to allow secure anchoring. Trim excess material after shaping the liner to the pond profile and anchor edges with rocks, soil or edging materials. When installing under gravel or decorative finishes, spread the protective layer evenly and check for wrinkles or folds that could trap debris. For repairs, cut a patch slightly larger than the damaged area and adhere it according to the liner material’s recommended bonding method or secure mechanically where applicable.

Usage recommendations

Before installation, verify the substrate is free from objects that could puncture the liner and consider installing a geotextile underlay for additional protection. Avoid prolonged exposure to sharp tools or heat sources during fitting. For long-term performance, inspect seams and exposed edges periodically and maintain surrounding landscaping to prevent mechanical damage.
