Protection for your pond liner

Pond liner underlay is a thick geotextile that is laid between your pond liner and the dirt beneath it. Underlay is key to ensuring the longevity of your pond as it protects against damage from punctures. We sell several underlay products from top brands like Gordon Low.

What is a Pond Liner Underlay?

Pond liner underlay is a tough and durable geotextile weave, created through the mechanical bonding of several sheets interwoven together. It's designed to prevent sharp roots and rocks from puncturing your pond liner, which can lead to your pond draining completely. We recommend using pond liner underlay with any pond liner.

Why should I buy a Pond Liner Underlay?

With pond liner underlay you can protect your pond. Most underlay is fairly cheap, so you can look at it as a form of insurance for your pond to prevent the loss of your pondlife or damage to your pump that can be caused when a pond drains.

What are the main types of Pond Liner Underlay?

The different types of pond liner underlay are characterised by different thicknesses or material types. Depending on how rocky or root-filled the area you need to cover is, you may want to consider a thicker underlay to ensure the safety of your pond.

What features should you look out for when buying Pond Liner Underlay?

There aren't really any other features to consider when it comes to pond liner underlay but it is worth ensuring you're buying the right amount of underlay. We sell our underlay in 2-meter squares so when placing your order all you need to do is enter the quantity you need. For example, if you're buying a 10 x 5m pond liner the quantity you would enter in the underlay amount would be 25. To work this out you simply do 10 x 5 = 50 / 2 = 25.
