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.

  • SUPER tough and heavy duty pond liner!
Size: 15x20 ft
LOVE the quality of this pond liner - we'd had neighbor cows come destroy our pre-formed liner and rearranged our whole set up when they climbed down into the pond to slurp up the melted snow run off last winter. Boy were we MAD! But hubby found this heavy grade plastic and we have re-done our pond and couldn't be happier. (we have since run barbed wire up to the top of the mountain and installed a cattle guard where we drive in to our property, so no more cows! YAY!) ... show more

  • Worked great
Size: 20x25 ft
Ordered this for an existing pond that had a torn liner, as of now 3 weeks later the liner seems to be holding up perfectly fine, will update if necessary

  • 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

  • Worked fine but stiff
Size: 20x25 ft
Worked good just hard to form cause very stiff. Had to let sun hit it to form it a little easier.

  • Water ponds liner
Size: 15x20 ft
I wouldn't recommend this product. I have bought other liners from other companies on Amazon and they worked great. We put this one in and all it does is leak. We have to go and buy another one.

  • 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

  • Pretty tough liner!
Size: 20x25 ft
