Thick heavy liner to stand the test of time!
We built this koi pond a few months ago and we wanted a high quality liner that would last for years with no rips or leaks. As soon as we felt the material we knew that is what we got. It is much bigger than what we needed, but that was by design. The pond is about 4x5 foot and 4 ft deep (with a 2ft shelf). We have koi fish living in it and get so much enjoyment from it, and it also adds home value. It was easy to put in (relatively to the job, which was very difficult as a whole). Would highly recommend if you want a long lasting pond.

Excellent customer service, great product
I bought the LifeGuard Pond Liner 5 ft. x 30 ft. 45 Mil EPDM Rubber and Underlayment Combo. The underlayment was correct, but the liner was only 20 ft instead of 30 ft. I discovered this after the 30-day return period, but the seller still responded quickly and professionally, sending the correct replacement right away. The new liner arrived promptly and is excellent quality—durable and exactly what I needed. Very impressed with the customer service and highly recommend this product and seller.

Start with this
I first tried to set my pond up with a heavy duty plastic liner. That was a big mistake. I should’ve gone with this EPDM rubber to start with. The plastic one I tried got a hole just trying to set it up. This one has held up to my dog jumping in several times trying to get a ball. We’re still training… I watched a few more videos and lined the pond with cardboard then the underlayment before laying out the rubber lightning, I am still working on making it pretty since winter hit, but it is holding up nicely out there.

Multi Purpose. Solved basement flooding.
I purchased this to divert water away from my house, so that water won't come into my basement. It worked! Water is not getting through into the ground around the back side of my house, where water was coming into the ground and into my basement. It has really solved a major problem. It was easy to lay down. Can be cut easily. Holding up very well in the sun. And is leak proof. Flexible, easy to work with. After the success with that project, I have now also used it on top of my roof. If no problems, I will leave the review as is. But if the roof patch doens't hold, I will update. I realize that this pond liner isn't made for roofs. But if it works, it works. (Sealing the edges of the liner on the roof with "liquid rubber seam tape" and covering the tape with "liquid rubber color sealant gallon".)
