Well worth the money
Excellent quality liner. So much better than the plastic disaster I purchased previously. Good thickness and weight, yet very flexible and relatively easy to work with considering it's weight. I used with a good underlayment for extra protection and feel confident it will work well in the long haul.

Thick, flexible, nice and heavy.
It is very heavy, nice and pliable, and needs a few people to drag it into place. It is so much nicer and more flexible than the last liner we had. Very nice. Thick, heavy and so far no leaks.

Watch out for spiders
When I opened the box there was a spider in the box. It did not run out of the box, but into the liner. In general, my wife and I don't eradicate spiders (I should have). Two days after installing the liner I noticed a bump on my back. It kind of looked like poison ivy (oozing), but the middle of the back is kind of a weird spot for poison ivy. A day later, fever and chills, plus muscle aches started. I went to the ER when I saw this black spot on my back (see attached picture). They said it was a spider bite. I don't know for a 100% that it was that spider, but checking pictures now it did look like a brown recluse. The timing seems to match from when I saw this spider. The initial charge from the ER $130, it will be a while before I see billing from the doctors and testing...we'll see what Medicare covers. I'm guessing it will be Thousands of dollars. A little pond project could turn into a big expense. The liner itself is of good quality.

Great product; No issues!
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!!

Heavy duty but easy to work with
Used as an impermeable surface to ensure rainwater drains away from foundation. Heavy duty enough that there’s no concern about placing it on and covering it with crushed stone. Still easy enough to fold up the wall under a termination bar and to cut with a pair of scissors.

Great for under-deck water protection, too
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.

Just buy it. You want a reliable liner? This is where to go.
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!

Great quality
I honestly haven't installed this yet as my project has been delayed. However, having purchased and installed similar liners in the past, I was impressed with the flexibility and quality of this one. I'm sure it will install easily, and hopefully last a long time
