yarlung2 Pack 4x7 Feet Pond Liner, 20 Mil Small Pond HDPE Mat Black KOI Pond Liner for Fish Ponds, Waterfall, Garden Fountains

I was looking for the thick rubbery type of liner material and this is not it. It is however a thick heavy plastic material. It just doesn’t have that rubbery squishiness to it. For what it is it’s okay tho. I put a couple folded layers under rocks in my pond on top of the original liner for an extra layer of protection while adding new rock features.

I wouldn't hesitate to use as a water garden but not a fish pond

Due to the somewhat smaller size, it's pretty easy to work with.

Very rigid. Hard to form well. They are thick though so I am not concerned about holes or tearing.

It was a 2 pack and one piece looked like it was cracked at the folding seams like they had a bunch of weight stacked on it....

It was to thick for what I was using it for

I used a pond liner to create a water proof cover over a spring tank where water accumulates from a spring.But Mr. Bruin came along and made his bed there and between claws and teeth punctured numerous holes and tears.I'll be using this pond liner to replace the old pond liner.The old pond liner was a bit thicker, but in a single layer.This new pond liner is a bit thinner, but will be double layered.I'm calling the double layer a + (plus).

I have a small 4 x 4 pond, about 2 feet deep. Visually, it seems quite small and the pictures on the product's website seem quite large. Also, the material on the product page looks thicker than the material that was sent to me. I think it is 20 mil, but I don't think it's the same liner that's in the ad. Also, once the material got hot in the sun, it smelled like an ant that has just been squished, so not pleasant. I was not able to build my pond, there was not enough material for me. If you have a tiny area to cover, this would work, but for anything worthy of being called a waterway or pond, not so much.

Great product I will be buying more as weed bearer.

Purchased in hopes to reline a pond in the backyard that sprung a leak last year, did everything correctly and since I paid for a pack of two thought it would be an opportunity to double line the pond, however both liner sheets seemed to have a hole in them somewhere. By the next day the pond had drained completely. Hoping to uninstall and ask for a refund.

This is a plastic material. Very difficult to work with, very difficult to bend, very stiff. I ordered this for a birdbath water feature, and the second one i used for a small waterfall. Worked pretty good for the small water feature(birdbath), but not so much for the waterfall. Finished the whole waterfall project just to have it leak somewhere, all my edges are fine, so i'm assuming its leaking somewhere underneath. So that being said, I'll be redoing my waterfall, so twice the work, just so I could save a few bucks. I would recommend buying a 45mil pond liner, way more expensive but way easyer and thicker material to work with.

This was more like a heavy tarp than a pond liner.

Not sure how this would ever work for a pond liner. Maybe to wrap up some body you were wishing to dispose of. Rigid and just not functional. Thankfully an easy return with Amazon
