Aquascape Underlayment - 20 Sq M

This pond liner underlay by Aquascape is made from Non-Woven Geotextile and this is a square sheet measuring 4.5m by 4.5m, which is perfect for pond and water feature installations. It is a large, flat, black underlay that is easy to install and covers a total area of 20.25 square meters.

The underlayment serves as a protective layer for both the pond liner above and below it. It prevents damage caused by rocks, roots, and other sharp objects that may puncture or tear the liner. Made from lightweight polypropylene, it has a non-slip surface and allows gases to escape easily.

The underlay can also be used as an overlay to provide extra protection for the pond liner. It is recommended to prepare the site by removing any sharp objects in the soil before laying down the underlay. Then, the EPDM 1mm pond liner can be added, followed by another layer of the underlay as a fish-safe overlay. Once everything is in place, rocks and gravel can be added around the pond.

It's important to note that while the underlay provides extra protection, it does not guarantee that the liner won't be damaged. However, it is a useful precaution against normal digging conditions and environmental elements.
