Pond Liner Heavy Duty HDPE 0.35mm Black

Create a durable, watertight base for your garden pond, koi pond or water feature with this heavy duty pond liner. It helps prevent water loss while forming a protective barrier between the water and the surrounding soil, supporting a cleaner and more stable pond environment.

Made from tough HDPE, the liner is designed to resist everyday wear and weathering outdoors. Its flexible construction allows it to be folded, bent and shaped to suit curves, shelves and edges, and it can be trimmed to fit your layout during installation.

Suitable for a wide range of projects including ornamental ponds, streams, waterfalls, reservoirs and landscaping features. It can also be used for self-watering raised beds and sub-irrigated planters where a dependable waterproof membrane is needed.

For best results, prepare the base carefully by removing sharp stones and roots, and consider adding a protective underlay layer beneath the liner to reduce the risk of punctures. Choose the size that gives enough overlap around the perimeter so the edges can be secured neatly with stones or edging materials.
