OASE - UNDERLAY 2.2M X 1M

Pond Underlay, not only protects your pond liner from rocks and root damage, it also gives a professional finish and a quality foundation for your pond.
Underlay is made from a woven material which is rot resistant and extremely difficult for sharp objects and roots to penetrate.

Using an underlay should ensure that you have no surprise holes appearing in your liner, requiring awkward repairs or expensive replacement.
