With a large selection of liners available, it is important to always determine whether the liner you choose is safe for fish that may inhabit the pond.
Aquascape 45 mil fish-safe EPDM pond liner leads the industry in quality and reliability. Backed by an industry-leading 20-year guarantee, Aquascape pond liner is the choice of discerning pond professionals. With superior elongation and lay-flat characteristics, it installs easily with no special tools required. Aquascape 45 mil EPDM Liner also has exceptional resistance to solar UV, ozone, and oxidation.
Underlayment is installed before the liner to prevent punctures from rough or rocky ground. Not only does underlayment provide protection for the liner, it also allows the ground to breathe from underneath. The fabric allows the earth’s gases to escape from underneath the liner rather than becoming trapped, causing gas bubbles to push the liner up into the pond.
