This is the one! Don’t cheap out on your pond liner!
If you’re building a pond this is the liner you want! It’s thick and durable. I built my pond on a budget, but this was one of the items I didn’t cheap out on. If you buy a cheap liner and end up with a tear or hole you’re going to have to breakdown entire pond and start with a new liner. Spend the little bit of extra money now and do it right the first time. I did a lot of research when building my pond and I’m so happy I went with a quality liner. You won’t be disappointed in this product.

Excellent product
I got a cheaper liner earlier this year and it was such a mistake. This one came onto the market at a good price and I bought it. They say it is heavy, but it is actually relatively easy to drag into place once unrolled. I installed it and filled it with water and for the first time the water level in my small pond has remained the same. I am completely pleased.

Excellent Price - Great Delivery - Highly Satisified!
After doing a lot of research both online and with local pond experts, we decided to go with the EPDM rubber pond liner despite the additional cost. Not only is it considered more environmentally sound and durable, but almost a necessity if you want fish without fear of contamination etc... Since a pond is not something we want to re-do every few years due to a poor quality liner, nor do we want to risk puncture/tears/rips that could ruin the plants and fish, this seemed like the best option and most cost effective in terms of time and expensve over the long run. BUT, when we began searching locally for an EPDM liner, the price was either very high OR the size options very small. Originally we thought about a 10x15 size but after calculating pond dimensions and depth (don't forget the depth), realized it was not sufficient. (As a side note, for those that are searching for a basic pond rule of thumb...take the desired length of feet, add 2 feet, and 2x desired depth to calculate width. Do the same for width). Decided to order this - very pleased with the purchase. The price per square foot was competitive with the best local prices per square foot for the smaller sizes yet we were able to get a larger dimension for a more useful pond size. Thickness is of a very nice quality. Seller was prompt, delivery quite rapid. This was the same liner a professional pond installer uses on his personal pond so should last for a substantial period of time. Overall, great product and a great price with superb service!

Pool for dogs
If you are looking for a thick durable pond liner and a company with great customer service then look no further! Bought my liner and it leaked out 2000gal in 3 days. I got in touch with there customer service and they had me 2 patch kits within 2days! This thing is super durable and I'm pretty sure will hold up to whatever you put on it. I bought this to use as a liner for a homemade pool. I built a pool that was 8ft wide 12ft long and 4ft tall. This liner is working perfect after the first night of having it filled. Water level isn't down at all and I couldn't be happier!! We built this mostly for our 2 large dogs (Newfoundland, Great Dane) to be able to swim at home and to be able to swim with them. Haven't tried putting them in yet but pretty sure this will hold up to there nails easily because this thing is thick! Very happy with our purchase and there customer service.

Thick, heavy, and easy to work with; Very happy fish
We built up and out on an existing pond, as we were having to add a new liner anyway (no injuries to the deer or fish, old liner damaged badly). This liner is big, it is heavy, due to the weather we were not able to lay it in the sun for a few hours to make it easier to work with. We were a few hours between storms on the install. It took 4 people, one at each corner to pick it up and put it in place. Once we got the center of the liner to the center of the pond, the liner fell in place, making it very easy to work with, smoothing it out was really all that was required. Then putting the blocks (that will get a stucco treatment later) on to hold it in place. It took about an hour to get the liner situated "just right", some blocks on it, water back in the pond, and the fish back in their home. Those fish are some happy fellows, they are loving the new liner and the extra space.

But this liner!
Just installed this liner 2 weeks ago and I loved its durability …So far so good! Unfortunately I bought a cheaper one before and it started to leak the first week! I had to tear everything apart and re install this one! Loving it !😀

Used it on a low pitch roof. Stuck it down with contact cement. Coated it with Liquid Rubber. Been some years now. I'm about to buy more to do another similar roof.

Delivery was over three weeks late but the liner is just what I needed. A little pricey.

Total scam! Bought the liner which arrived defective. It then cost us $195 to return it to Amazon.
