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 20 ft x 25 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.

  • 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

  • Instant small pond
Size: 20x25 ft
Always wanted a small pond in the back yard. Easily achieved with this liner.

  • I wouldn't Recommend
Size: 15x20 ft
I wouldn't Recommend for small koi ponds or pond with shelves. Material is very rigid and does not easily conform to things greater than 45 degree angles. I think that it would be best suited for ponds, drainage ditches. If I had to do it again I would spend the extra money and purchase 45mil Rubber liner ... show more
