The media could not be loaded. First let me say that I've never built a pond before and I completely winged it. This pond liner made the task very easy. Basically I dug a roughly 4 foot by 4 foot square hole in a spot in my yard that varies a little in depth from 12 to 18ish inches deep. I laid the pond liner out in the sun for a bit to make it more pliable, then dropped it into my hole. I then walked around on top of the liner to use my weight to push the liner down into the depth of the hole, filled it with water, placed some pavers around the edges to hold the liner in place and cut the liner to size with a box cutter / razor blade. I left about 4 to 6 inches of "lip" around the edges of the pond on which I placed bags of river rock to hide the liner but to leave a little extra liner in case it settled or stretched at all. So far it is holding up extremely well and I've had as many as 6 ducks swimming around in my little pond at one time. If I were to do this over the only change I'd make is that I might consider doing a double layer of this material in case one layer gets a hole in it but it does seem extremely sturdy. It's essentially extremely thick black plastic garbage bag material. Another possible use for this is that you could use it to kill grass or weeds in a section of your yard if you wanted to. It would also work well as a waterproofing barrier for leaky RVs or as patch material for tents or anything else that leaks and shouldn't leak.

I bought this liner like 2years ago in my outdoor pond. Put it in (not professionally BTW, lol). Its STILL leak proof. Been thru a few hurricanes. Me and my three young boys get in it and splash around 1-2 times a week. Its got fish in it that all look healthy too. Just trying to say its a good liner. Maybe not if youre doing lots of boulder under water, it tells you its not as thick as other competitors. But I didn't want to spend 400$ on a liner, haha.

Bought for our above ground turtle pond. I agree with other reviews that it is very stiff and hard to move around. Leaving it out in the sun did help some. It is holding up very well. The pond is made with cinderblocks and this liner and is approximately 350 gallons.

This is not rubber it’s plastic and it won’t form to your pond at all! I can’t understand how this has such a high rating with so many reviews. I spent 3 days digging out the perfect pond structure with shelves and this terrible liner wouldn’t form around the structure. It’s too thick but at the same time is punctured easily by even a small rock or even within its own folds. It has scratches all over it right out of the box. Because it’s not flexible and won’t form to the shelves in your pond there is no way to disguise the liner with rock. It will crack along the seams and or puncture under any rocks you place on it. This is not acceptable! This will ruin your project do NOT BUY!

So far so good. Had a large hole in our pond liner and this patch was the perfect size and easy to install. Not to thick and was easy to cut as needed. So far is holding up well. Only issue was it was delivered on a hot day, so some of the glue started to seep out and stuck to the plastic bag so we had to cut it out of the bag.
