Types of Pond Liner: Material Suitability

Depending on our customers’ needs and financial constraints, we provide a variety of pond liner materials. British-made butyl rubber liner is what we always advise for garden ponds. Simply put, it’s the best pond liner material available!

Why? Here are just a few examples that come to mind immediately.

It’s 100% British manufactured for starters

• Butyl Rubber can be fully vulcanised (welded) by our factory technicians, providing inseparable seams. We don’t use glue or tape as it doesn’t last nearly as long as a quality permanent vulcanised weld.
• It is a liner safe for fish and entirely non-toxic to all aquatic life. Toads, newts, and frogs are included in this. 
• Because it is UV stable, the material won’t split or perish when exposed to sunlight and given time to dry out. 
• It is renowned for its toughness, is extremely durable and has an anticipated working lifespan of more than 50 years. 
• We guarantee our workmanship, and our genuine British Made Butyl Rubber Liners come with a Lifetime Warranty and are offered at the very best price you will find on the market. As a result, for a relatively small up-front cost increase, the savings are immeasurable over time as you won’t need to replace the liner due to failure for as long as you would with other less expensive materials available today.

Of course, we are aware that finances can sometimes be limited, so we’ve formulated a British-made EPDM material just for this purpose.

Many of the advantages of Butyl Rubber, like flexibility and UV resistance, are present in our fish-friendly EPDM. Our EPDM is projected to last 30 years, whereas butyl rubber has a 50-year lifespan. Our EPDM comes with a genuine 10-year warranty.

Do I Need Underlay And Overlay For Liner Protection?

Our Landflex G3000 Geotextile is manufactured from a hard spun polypropylene fibre and is perfect for use with our rubber lining materials. It protects the liner against punctures from sharp stones etc. If you choose it as an option in our online liner calculator, the appropriate amount will be automatically added for the size of your pond liner.

Underlay is advised for all of our flat sheets, box-welded liners, and made-to-measure liners.

Overlay – When a natural appearance is desired, such as when putting stone or earth on top of the lining, an overlay is advised for use with flat sheet liners. You will need to weigh it down with soil, stones, or gravel because the material is light and will float. It gives your pond a completely natural appearance and is perfect for luring wildlife to visit. We don’t recommend overlay for ponds with vertical or steep sides as it isn’t possible to cover it with earth or stone.

Ask one of our experts for instructions if you need help folding the rubber liner back on top of the overlay to stop capillary action.
