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.

  • It works
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.

  • Great liner!
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.

  • Extra thick
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

  • SUPER tough and heavy duty pond liner! BUT HAS PINHOLES!!!
LOVED!!! (PAST TENSE) 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!) UPDATE one year later... (not long enough in our opinion) - the pond is leaking and needs refilled daily - we have a trip planned and MUST address this immediately - It is no small task to drain the pond, remove fish, remove and repair liner, replace the decorative BIG HEAVY rock around (not to mention trying to salvage as many of the flowers growing around it). We are NOT so happy with this liner anymore. We discovered MULTIPLE pinholes - all of which contributed to the growing leakage that had become a serious problem. There is NO excuse for the pinholes. We actually installed a piece of carpet UNDER the liner so that NOTHING could POSSIBLY pierce it from underneath. It just wore OUT entirely in ONE YEAR. SAD SAD SAD. ... show more

  • NEEDED THIS FOR MY POOL
THIS 15' X 20' POND LINER IS A PERFECT PART OF MY UNDERLAYMENT FOR UNDER MY ABOVE GROUND POOL...IT IS 20MIL THICK SO THERE IS NO WORRY ABOUT ANYTHING DAMAGING MY POOL LINER

  • Not pincture resistant
Not the kind of material I was expecting, the rubberized material which I got from years ago is more flexible and durable and moe puncture resistant.

Used to line my garden. Quality material at a good value. I would recommend.
