Description

Pond Liner is the foundation for any Koi pond, water garden, or waterfall. From residential backyard ponds to commercial water features. 45-Mil EPDM LifeGuard Pond Liner is the preferred choice of professional installers Because its is flexible , puncture resistant and will last at least 25 years! LifeGuard EPDM is an elastomeric compound (rubber) that is manufactured from ethylene, propylene, and a small amount of diene monomer. These ingredients are synthesized to produce a product that exhibits a high degree of ozone, ultraviolet, weathering and abrasion resistance, and outstanding low temperature flexibility. These ingredients also contribute to resistance to acids, alkalis, and oxygenated solvents (i.e. ketones, esters, and alcohols). Don't Be fooled by Chinese companies marketing Plastic as EPDM! The Best EPDM RUBBER LINERS ARE MADE IN THE USA Features and Technical Specs: The formula for sizing a pond liner is: (Pond Length') + (2 x Pond Depth') + (2') = Liner Length' (Pond Width') + (2 x Pond Depth') + (2') = Liner Width' So... if you want a finished pond that is 12' long, 7' wide, and 3' deep; then using the formula above, the liner size you need is: (12') + (2 x 3') + (2') = 20' Long (7') + (2 x 3') + (2') = 15' Wide This basic formula will work for ALL pond shapes. Fish Safe EPDM LifeGuard Pond Liner is Certified Fish & Wildlife Safe by Guardian Systems, Inc. Natural and beutiful Water Gardens are great habitat for plants and fish. Just add water and your yard will come to life! Easy to Shape and Fold EPDM Liners Are strong and Flexible so they make waterfalls like these easy to build.

  • Great price, works great, easy to install
Material Type: 5' Width Style: 30' Length
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. ... show more

  • Great product; No issues!
Material Type: 40' Width Style: 90' Length
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!! ... show more

  • Toxic-free Pond Perfection
Material Type: 15' Width Style: 15' Length
Exactly what I needed for my little duck pond. The 15' x 15' liner is thick, without holes, and, for the most part, not toxic to the environment. For the price, I will always buy from this company.

  • Quality liner but dirty
Material Type: 15' Width Style: 15' Length
The liner was delivered quickly and proved to be a quality liner. It was disconcerting to see pine needles folded within it.

  • Thick, Easy to Install
Material Type: 15' Width Style: 25' Length
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. ... show more
