Pond underlay is essential when building your new garden pond. Underlay will protect your pond liner from any sharp objects which you may uncover or disturb while you are digging, as well as offer great future-proof protection from roots from plants such as trees or large shrubs.
When using underlay, secure this to the hole you have dug making sure that you cover the sides with underlay, as well as the base of the pond. As go around installing the underlay, make sure that you remove any loose stones, imposing roots, and debris that you have uncovered when digging.
Although pond liner is very strong, it’s important to remember that a full pond will weight several tons, so underlay will give the liner the best security by offering padding between the liner and the ground, ensuring the success of your pond installation.
