Protect Your Pond Liner with Underlay

What is Pond Liner Underlay? Pond liner underlay is a thick geotextile layer placed between your pond liner and the ground. This essential component ensures the longevity of your pond by protecting the liner from punctures.

Why Use Pond Liner Underlay? Pond liner underlay is a tough and durable material made from interwoven geotextile sheets. It's designed to prevent sharp roots and rocks from puncturing your pond liner, which could otherwise cause your pond to drain completely. We recommend using underlay with any pond liner to provide extra protection and peace of mind.

Benefits of Pond Liner Underlay Using pond liner underlay protects your pond investment. Most underlay options are affordable and act as insurance to prevent the loss of pond life or damage to your pump due to pond drainage.
