Pond Liner EPDM Rubber 900gsm

Create a dependable, watertight base for ponds and water features with this heavy duty EPDM pond liner. The flexible rubber sheet is designed to shape neatly to shelves, curves and uneven ground, helping you achieve a clean finish with fewer creases and less stress during fitting.

Made from EPDM (ethylene propylene diene monomer) synthetic rubber, it offers strong resistance to weathering, UV exposure and ozone. The material remains pliable in a wide range of conditions and is built to withstand everyday garden movement, helping reduce the risk of splits, tears and cracking over time.

Ideal for new builds and refurbishments, this liner suits garden ponds, koi ponds, wildlife ponds and decorative water features such as waterfalls and fountains. It can also be used for other aquatic and water containment projects where a durable, flexible membrane is needed.

For best results, prepare the base carefully and consider using a protective underlay to help guard against roots, stones and sharp debris. If you need to join sheets, use compatible EPDM seam tape and adhesive to maintain a reliable seal and extend the life of the installation.

Choose your pond liner size

The listed options run from 1 × 1m to 10 × 10m, including rectangular sheets such as 2 × 10m and 4 × 5m. Measure the complete area to be lined, including the pond depth and shelves, before selecting a size.

The 900gsm figure describes material weight per square metre; it is not a thickness measurement in millimetres.
