Features

  • LLDPE Material: The pond liner is made of LLDPE material, pro-environmentally, sunlight-proof, weather-proof. It can restrain the penetration of harmful substances into the pond and give your fish and plants a secure living environment.
  • 20 Mil Thickness: This small pond liner is strong enough to withstand extreme weather conditions, more durable, tear-proof, and puncture-proof. In addition, good waterproof performance can effectively retain the water in your pond.
  • Flexible & Pliable: The fish pond liner has good flexibility, easy to bend and fold. You can cut it in various shapes to fit all irregular surfaces(e.g., waterfalls). For better flexibility, you are recommended to lay the liner under the sun for 10 to 15 min before use.
  • Aging-proof & Durable: Our waterfall liner is designed with excellent durability, high tensile, and impact strength. The size of 15 ft x 20 ft is ideal for small ponds. The lifespan can live up to 50 years without any exposure, and it can also last for ten years under intense sunlight.
  • Wide Application: This large pond liner is a perfect choice for agricultural or home use, such as water garden, fish pond, backyard waterfall, golf course, artificial lake, riverway, aquaculture farm, sloping side, rooftop, etc.

  • Good material easy to work with

Duck pond and it worked great The dogs beat them to it though

  • It works
Size: 15x20 ft
It's not very flexible and has folds. It is also expensive. I've had it in my pond for a couple of weeks now, and it is holding water. I will update you if it breaks.

  • Extra thick
Size: 15x20 ft
Love these liners, they are extremely thick but will still tear easily if you drag them and they snag on something so be careful on assembly

  • Quality Material

  • Great liner!
Size: 15x20 ft
Used for our goldfish pond and it is very well made. I have huge rocked stacked around the outside and it never rips or tears. No leaks at all.

  • Can't stop the Leaks!
Size: 20x25 ft
Installed 20x25 liner. Finished my stonework and added water. Water dropped over night. Searched liner and patched a couple of leaks. Refilled - dropped again. Carefully removed stones below water level, patched anything that look like it might leak. Refilled - dropped again. Last try was removing stones beneath the waterfall -found two suspected leaks, patched, refilled. Still dropped. I got my money back from Amazon and am buying a 45 mil EPDM rubberized liner. Will have to disassemble all of the rocks remove the old liner and put in a new one. Should have done the 45 mil the first time. What a pain in the ass. NOT Recommended. ... show more

  • Too stiff
Size: 20x25 ft
Was not easy to work with, was expecting it to be more flexible but it’s extremely hard to lay out and the wrinkles were huge and doesn’t fold well and wrinkles are soo stuff they don’t lay down, instead stick straight out. It was very thick though so credit where it’s due but not for a rounded pond unless u cut it several places and tape it back together causing weak point in the water barrier. ... show more

  • Worked great
Size: 20x25 ft
