      20 mil Polyethylene Pond Liner?

      Wondering how 20 mil Polyethylene liner compares to 40 mil EPDM. Durability, ease of installation, less or more folds once in pond, lifespan, etc.? Thanks!

      I recently purchased BTL Liners BTL-40. It is extremely tough and durable, but it was very hard to fold, I don't think it's quite supple enough ... if that makes

      I see the 20 mil RPE liner used a lot by hydroponics people. Helped set up some tanks and it folds well for perfect rectangle and squares. Have yet to see someone use it for an ornamental fish pond. Personally I wouldn't want to use it if the pond has many non-square folds and curves.
