Why Use Pond Underlay?
Placing pond liner underlay protects your liner from sharp objects such as stones, roots and anything else that could tear it. Although you can use old carpet or newspaper instead, they are never quite as good as they will eventually rot down and stop protecting your liner.
Other people place a layer of soft sand under the liner. Although this will not rot down, it is quite difficult to keep in place during the installation of the liner.
We therefore recommend using a purpose made pond liner, which will last and protect your liner for years to come.
These come in differing qualities, each designed to suit different liners. Many companies will only guarantee their liners when you use one of their recommended underlays.
