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.

  • Best liner you can buy.
Material Type: 15' Width Style: 15' Length
Excellent liner, no issues, thick, and best value for a 45 mil on the market. Also came with a free underlayment.

  • Great Quality
Material Type: 10' Width Style: 15' Length
This material is absolutely perfect for the project I used it for. Used it to line a 300 gallon metal trough where it conformed to the shape much better than the plastic liners and I don’t worry about this one puncturing or leaking.

  • Heavy and looks like it will last
Material Type: 20' Width Style: 20' Length
This is a very heavy pond liner and works well to line larger ponds than what you could put in insert in. We first ordered another type of liner that basically was just a tarp. When we got it my husband put it in, filled it up and then realized water was leaking from somewhere not sure where the tear was. We never found it. Just took it out, ordered this one instead and replaced that it hasn’t been in very long, but it looks to be like it will last for a while ... show more

  • Best pond liner seen thus far

My son and daughter-in-law purchased a different pond liner and thought it was a high quality product until they saw mine. They were jealous because mine was so much better than theirs.... 5 stars!!!!
