Wondering "What Does EPDM Stand for in Pond Liners?"

There are quite a few different types of pond liner on the market today. From pre-formed pond liners all the way to concrete for large expansive koi ponds. The most popular is flexible EPDM rubber pond liner.

If this confuses you and makes you wonder what does EPDM stand for in pond liners let me explain.

EPDM stands for Ethylene Propylene Diene Monomer. Which is exactly why they decided to abbreviate it. Imagine ordering up pond liner and saying I would like to buy Ethylene Propylene Diene Monomer flexible rubber pond liner please.. haha

What does this mean to you and why would you want use it

Just like a house, pond liner is your ponds foundation. It is extremely important. Just like you would not build your house on top of sand, you should not try and use a cheap pond liner.

Installing a cheap pond liner will lead to multiple service calls, a leaky pond, and quite possibly a massive amount of labor to fix and replace.

Using a quality EPDM pond liner will give you that good foundation and let you sleep at night knowing your pond will hold water for many, many years. EPDM liners have been tested and when exposed to sunlight they will only degrade 1/2 a mil a year. This would give you a life span of about 90 years after installed! On top of that, we cover the pond liner in most installations so you could get even more life out of it.

Warranty - We wouldn't even consider using a pond liner if it does not come with a warranty. And we suggest you shouldn't either. Most EPDM liners come with a 20-30 year warranty.

Two of the Most Popular EPDM Rubber Pond Liners on the Market

If you have decided to go with EPDM as your pond liner of choice the two major players in the game are Firestone, and now EasyPro.

45 mil Pond Gard EPDM Pond Liner

Firestone has been in the game the longest and is the biggest pond liner company out there with their 45 mil Pond Gard EPDM pond liner. But, rising costs have caused some pond owners to look for alternatives.

EasyPro Intergra 30 Mil EPDM Pond Liner

The newest pond liner currently on the market is EasyPro Integra 30 mil EPDM pond liner. Is is a more lightweight fish safe liner that is cheaper than the 45 mil pond liner by Firestone, but not as heavy duty. If you have a light weight project and your budget is tight Integra liner by EasyPro is the way to go.

TOXIC EPDM Pond Liners

Now that you know what EDPM stands for in pond liners you may start searching the internet. One thing you may notice is that roofing liner is also made out of Ethylene Propylene Diene Monomer (EPDM) and is cheaper than what you find at online pond websites.

Now at first you may be thinking you found the holy grail and cheaper pond liner. But, it could lead to problems.

While some pond owners have used roofing liner for their projects, we have also heard of owners who have come home to a pond full of dead fish that were built without a "fish safe" EPDM liner.  Roofing liners can be made with mold resistant chemicals, or others and its not worth the risk of killing your fish for the small amount saved.

In summary, if you found yourself asking "what does EPDM stand for in pond liners" it is Ethylene Propylene Diene Monomer and the liner of choice of nearly every water feature built today. Click on the links above to learn more about EasyPro and Firestone EPDM liners and purchase.
