Pond liner

My personal choice for pond liner is EPDM rubber. It’s what Ive used on all my personal ponds.

I have also used HDPE, that was on my grey water wetland. I constructed that over 10 years ago and it’s still going strong.

If you are going to construct an ecosystem pond with rocks and pebble I would certainly stick with EPDM rubber. I’ve put two links below for EPDM rubber.

HDPE and LLDPE are more rigid, but I think they are a perfectly fine choice for a small fish pond, with no rock and pebble.

You might also like to view geotextile underlayment to protect your liner.

There’s a video at the bottom of the page where I talk about the different choices of pond liner.
