When building your own backyard pond or water garden, it’s always nice to have total control over how big, deep, and wide it would be. This gives you enough room to let your creative juices flowing and achieve a specific aesthetic you can be proud of.

In this case, preformed pond liners that come shallow and small just won’t do the trick. This is where the Commercial Pond Liners come to save the day! These pond liners come in much bigger sizes and adjustable dimensions to allow you to let your imagination run wild with your masterpiece.

With a flexible pond liner that conforms to any shape, there really is no limit to what kind, shape, size, or depth of water feature or pond you can create.

There are hundreds of flexible pond liners out there, but in this article, we have rounded up the top 4 best, highest-rated, and most favorite liners, so you don’t have to look much farther. We also included a buying guide for your reference. So, what are you waiting for? Scroll down to learn more!

 

What to Consider When Buying a Commercial Pond Liner

Just like when purchasing any other product, there are several factors to consider when choosing the best pond liner for you. Listed and discussed below are some of the most important ones that we also used to come up with the top 4 commercial pond liners featured here!

 

Size

The first thing you should consider is the size or dimensions of the pond you are making. Pond liners come in a wide range of different sizes starting from 5 by 5 feet all the way to something like 50 by 100 feet or bigger to accommodate the requirements of your pond.

It is essential to know the right size of pond liner to buy based on what shape, how deep, how wide, and how long you envision your pond to end up looking. Are you looking for a small or large pond liner?

Later, we have linked the different available sizes of each pond liner model we reviewed to help you choose the dimension and size quicker.

If you’re not sure how much liner you will need, here are two ways to figure it out:

Method 1

Draw or sketch a plan of your pond on paper. Then, dig your pond based on this plan. Once done, you can take measurements of the bottom surface of the pond.

Method 2

To calculate the appropriate liner size, you can also utilize simple math. This is easier if you have the measurement of the pond’s depth, length, and width. Since liner sizes are expressed in width by length units, you need to compute for these dimensions.

The length of the liner should be equal to the measure of the pond’s length, plus twice the depth plus two.

Liner length = Pond’s Length + (2 x Pond’s Depth) + 2

For the width of the liner, simply do the same math but use the pond’s width instead of the length so here’s the formula:

Liner Width = Pond’s Width + ( 2 x Pond’s Depth) + 2

Both of these calculations work for most units, including meters, feet, and yards. Using these formulas, you should have sufficient liner to cover the pond with enough extra material for the sides.

 

Pond Liner Material

The next thing to consider is the pond liner material. Pond liners can be made using several different materials, but the three most common ones are EPDM, PVC, and RPE. Each of these has its own advantages and disadvantages, so the ideal material for you depends on your application, preferences, and needs.

In the following sections, we will talk about their characteristics and unique benefits and drawbacks:

 

Ethylene Propylene Diene Monomer (EPDM) or Rubber

EPDM is the go-to material for pond liners in the construction of different kinds of ponds. However, RPE liners have risen to the same stage in recent years. Here are the facts about EPDM liners:

Advantages

○    Made from very flexible rubber

○    Suitable for compact shaping

○    Versatile

○    Easy to fold around the corners

○    EPDM sheets can be put together using liner tape

○    Fish and plant safe

Disadvantages

○    Need an underlayment because of its flexibility and softness

○    EPDM sheets cannot be welded together using hear

○    Heavyweight and hard to ship

○    Least puncture-resistant out of the three materials

 

Polyvinyl Chloride (PVC)

PVC liners are also popular mainly because they are the least expensive among the three materials. They are also easy to find. However, their disadvantages far outweigh this advantage.

Advantages

○    Lighter weight than EPDM

○    More puncture resistant and slightly stronger than EPDM

○    Comes with added plasticizers to improve liner flexibility

○    Affordable and easy to use

○    Can be seamed together using heat or liner tapes

Disadvantages

○    Heavier than and not as puncture resistant as RPE liners

○    Not as flexible as EPDM liners

○    Plasticizers can cause splits and cracks in the liner that can threaten wildlife

○    May contain trace amounts of arsenic and other toxic substances lethal to fish

○    Not suitable for cold climate

○    Not UV-stable and can have negative effects upon exposure to direct sunlight

 

Reinforced Polyethylene (RPE)

By far the strongest and most durable of all pond liner materials, RPE is another good choice. However, it still does have a few imperfections.

Advantages

○    More puncture resistant than the other two materials

○    RPE liners are only a third of the weight and half the thickness of PVC and EPDM liners, making them easier to produce in larger sizes

○    Easier to install

○    Packs smaller than EPDM or PVC liners

○    Can also be folded around the corners

○    No need for underlayment

○    Extremely durable and are known to last for 40 years or more

○    Safe for fish and plants

○    Can be welded together using heat

Disadvantages

○    Not as stretchable as EPDM liners

○    Not as easily accessible

 

Now that you know more about each material, it should be easier to spot which pond liners will be more suitable for your specifications. While RPE is obviously the best choice in terms of durability, ease of installation, and size, the other two materials can compete in terms of availability, affordability, and versatility.

 

UV Exposure

Another important consideration is whether or not your pond will be directly exposed to sunlight. Sunlight and UV exposure is one of the biggest evils that can damage your pond liner. In most cases, a liner will only hold water efficiently if placed under cement since dirt will only slide off and expose your liner.

If you think UV exposure will be an issue, and you don’t plan to use cement for your pond platform, the best option for you is to use an EPDM liner, which is UV-resistant.

 

Warranty

Different manufacturers produce liners that vary significantly in terms of durability and performance. For your peace of mind and to ensure you are getting a good quality product, it is vital to look for something that comes with an excellent warranty.

While pond liners can last for years, it is still best to look for longer warranty periods so you can be secured of getting your money’s worth in case a problem arises in the future.
