Is Pond Liner Expensive

EPDM liners are more expensive than RPE because they’re made out of rubber vs polyethylene, and it just so happens that rubber is a more expensive material to manufacture. … For example, in large ponds, we usually recommend RPE over EPDM rubber because it’s stronger and lighter AND less expensive!

How long do pond liners last?

To summarize, a rubber pond or flexible PVC liner can last for 20 years or longer as long as they are installed over a protective underlay and secured in place using the right edging materials and are protected against visits by clawed animals.

What is a good thickness for a pond liner?

When tree root penetration is a problem or there’s regular traffic in and out of the pond, liners 30 mils and thicker are recommended even for basic ponds. Even backyard ponds benefit from a 30 mil or greater liner to prevent rocks and roots from wearing holes in a thinner material.
