1000 lbs of EPDM liner (1 piece, 90' x 40') arrived on a pallet just in time. Delivery coordination and communication was great and no issues there. I laid used carpet under the liner to protect it from possible roots etc. I wish I had a few more people to help. It was not an easy task for 6 of us to get this done. We had to work smarter as this is a really heavy liner but managed to get the job done in approx 1hr. Only a few things left to do like booting a couple pipes and then laying the larger rocks down on the shelf. The liner however is perfect, no rips or holes that I can see, very strong and also flexible. I'm not a pond pro so I've never worked with EPDM before but I'm impressed. Amazon had the best $ price for this particular size and free delivery. Could not find any local shop to beat Amazon, so thank you Amazon!!

I got this to use as water protection from my deck, that is, to keep it dry underneath. This stuff is as thick as a tire inner tube and it's real rubber. It does a great job. Saved hundreds over the name brand projects that's meant to do this job, and it's better stuff. You have to install at a certain way so make sure you check for YouTube videos about how to do that if you want to use it for this purpose.

After researching, i decided on an EPDM liner, then eventually chose this one. My pond is about 7'x10' (kidney shaped) so I chose the 10'x15' liner - thinking it was going to be much too large, but it turned out to be just the right size. The material is thick and heavy, and seems like it will last a long time. As with other reviews, I noticed the liner was covered with dust - maybe from manufacturing? maybe for shipping so it doesn't stick to itself? Whatever it was, there was a lot of it, and it's not easy to remove. I laid mine out on the yard and hosed it off, then mopped it, then hosed it again, then mopped again - and did that for both sides. Because I was replacing an old liner, I already had fish and wanted to get them back in the pond ASAP, so the liner went in on Sunday and the fish back in on Monday - no issues so far (it's been about a week). My last EPDM liner lasted almost 20 years, and would have lasted longer had I not punctured it. This liner seems of similar quality.

This pond liner is the real deal. Works just as it should has been in place for over 5 months with no leaks. We used it under an upper deck and above a lower deck to provide a water diversion system to keep the lower deck dry. It was high quality, easy to install considering we installed it above our head. It was not sticky or tacky at all. And it is really the best price I found.

Let me start off by saying that here in Texas, it’s very hard to find a reliable pond, minor for massive ponds, let alone to find any at all! I’ve only seen smaller pond liners for sale at Lowe’s or stores like that and I would not trust them. For starters this pond liner is 45 ml and made of EDBM (forgive me if I spelt that wrong) and is built to resist tears and be able to handle heat and sun. To be honest it wasn’t very heavy but then again, I’m a pretty strong guy. HAHA. Just be very careful, to prevent tears when you were first building your pond for example when you are lifting heavy rocks over it, etc. another thing to look out for is to make sure that you pull any sticks roots, rocks or anything sharp underneath the liner as the weight of the water is going to be constantly pushing down on that sharp object and could cause a rip even on the worlds, best pond liner. On that subject, I actually noticed a large sticking into the liner that I had missed, which was my fault and it never poked the hole through this liner. I ended up just snapping it to relieve the tension. I really do hope I feel the same about this product years from now the same as I do right now, because I really got lucky, as you could tell in the photos because this is anybody’s dream pond and it could be yours too. as the title suggests, just buy it already, and build the pond of your dreams!

We have a 20 x 15 pond dug out. We had four people to lay out the underliner and pond liner. We thought it would be super-difficult to lay down the liner. It wasn't. It was good to have one on each side, but we could have done this with two. It was cut exactly to the dimensions we ordered. It is covered with a powdery substance, but that was easy to clean off. It's nice and thick. Was fairy easy to install. We will see how it ages. At this point, we are thrilled.

I ordered 45-mil EDPM from 2 different vendors. The other was shiney and tough to shape. This looked more like a tire inner tube, and shaped nicely. This is the one you want.
