Pond Liner Heavy Duty HDPE 0.35mm Black

Create a long-lasting waterproof barrier for your pond or water feature with this heavy duty pond liner. Designed to help prevent leaks and reduce soil contamination entering the water, it supports a cleaner, more stable environment for fish and plants.

Made from HDPE, the liner is tough yet flexible, allowing it to fold, bend and conform to curves, rocks and waterfalls. Its UV-resistant construction is intended to cope with outdoor conditions while remaining resistant to cracking and everyday wear.

Ideal for garden ponds, koi ponds, streams, waterfalls and decorative water features, it can also be used for planter and water-garden projects where a dependable waterproof membrane is needed. The sheet can be trimmed to suit your exact shape, and multiple sheets can be joined to cover larger areas.

For best results, measure your pond at its maximum length and width and choose a liner slightly larger than the hole so you can allow for overlap and final trimming. Using an underlay layer beneath the liner can help reduce the risk of punctures from stones or roots and extend the liner’s service life.

Once installed, allow the edges to overlap onto the surrounding ground and secure with smooth stones or suitable edging to keep the liner in position.
