Top 5 Best Pond Liners to Buy🥇(Dec 2024)

Last Updated: 21 December 2024

In this article, we’ll be talking about the 5 best pond liners that you can use for your garden pond.

However, firstly we’re going to talk a little about pond liners, the different types, materials and sizes that you might find, and which one is suitable for certain types of usage.

Either way, we’re sure that you’ll be confident knowing which pond liner is suitable for your specific needs after reading this article.

So, let’s begin!

 

What is a Pond Liner

Pond Liners are water-tight, impervious geomembranes that are used for the reservation and withholding of water in a public or garden pond. They are commonly used and placed over an underlayment, helping to prevent damage and keep the geomembrane in optimum condition.

 

Types of Pond Liners

There are several different types of pond liner material, the most common include EPDM, RPE and PVC liners. All of these have unique advantages and disadvantages, and the ideal type for you can be determined by your applicational usage. So let’s talk about each of the benefits and flaws:

EPDM/Rubber Liner :

Advantage:

• Highly flexible, therefore suitable for very compact shaping, versatile for 90-degree angles.

Disadvantages:

• Slightly softer than RPE liner, and requires pond underlayment to be installed before placing. Although once pond underlayment is installed, this greatly compensates for the softer material density.

---

PVC Liner :

Advantage:

• Slightly stronger than EPDM liner, although this is not a general rule and may vary from brand to brand.

Disadvantages:

• Not as flexible as EPDM pond liner

---

RPE Liner :

Advantage:

• Doesn’t require pond underlayment
• Lightweight

Disadvantages:

• Not as flexible as EPDM
• Not as commonly used or found

Pond Liner Sizes

Pond Liners are made in a range of different sizes to help accommodate for different tastes/requirements for their garden pond creation. They usually begin around 5 x 5 feet (small pond liners), but can be found leading all the way up to 35 x 35 feet (large pond liners).

We’ve linked to all of the different sizes of pond liners that we’ve featured in this article, making the process quick and simple for those who know their liner size and dimension requirements.

Installation of Pond Liner

We’ve featured all of the necessary steps for you to take, to help ensure a successful liner installation; So let’s get to it!

1. Do some research (potentially call your local council surrounding permission and whether or not there are pipes or obstructions below your garden, that would prevent you from installing a pond.
2. If everything is fine, get the appropriate equipment for your installation, this includes a rope, shovel, hose, and a horizontal measuring leveler.
3. Pick a level location in your garden where you would like your pond to be. Bear in mind that a partially shaded location is more ideal, to help keep your fish cool and prevent the growth of algae within the pond; For more information on controlling pond algae, Check out our article on how to control algae in a pond.
4. Design your water-garden on a detailed plan, with ideas about the size, shape, and depth; The depth can be variable, with certain parts being deeper than others, although bear in mind that this will dictate the required liner size. Also, keep in mind that most ponds have plant shelves that are 9-12 inches in size.
5. Begin digging your pond
6. Backyard pond liners are usually made from plastics/rubber, and therefore the main vulnerability for these liners is abrasion caused by sharp objects such as jagged-edged rocks and stones. Therefore it’s important to make sure that the area directly below where the liner will be placed is smooth and rid of any potential piercing objects,
7. Place a layer (2-3 inches) of sand over this area of ground will ensure that necessary steps have been made to reduce the risk of the liner being damaged. Alternatively, you can use pond underlayment material instead of sand.
8. Set the pond liner in the pond, and place some rounded rocks within the liner to keep it in place. If you’re adding a rock waterfall on the outside, you can add this now.
9. Begin filling the pond with water, and smooth out the pond liner if any major material wrinkles start to form.
10. Setup your pond pump, but do not plug in just yet (for solar pond pumps, place the UV panels out of direct sunlight for now), and either attach the outlet hose if you’re using it for your waterfall (Find best-selling Rock Waterfalls on Amazon), or attach the fountain head attachments which is usually included within the pump kit.
11. As the pond is filled, use decorative rocks to place along the outside of the liner, helping to secure it’s position further. Then trim the excess pond liner.
12. Plug in your pond pump to a GFCI-approved outdoor power outlet, or for solar pond pumps, place the UV panels in direct sunlight to begin the water flow and aeration.
13. Add fish and aquatic plants to the pond/koi pond or water garden if you so desire.

Alternative to a Pond Liner

An ideal alternative to using a fish pond liner material is to use a preformed pond liner. Preformed ponds are great because they allow for a consistent look without you having to sculpture your own pond yourself; Ideal for the aspiring pond owner who wants minimal installational hassle.

How to protect my Pond Fish and plants?

Once you’ve placed your pond liner into the dug hole, and your water pump is working to oxygenate and aerate the water, you can then add your aquatic plants and fish.

However, there are many threats that pond fish can face, especially from predators lurking up above. Therefore consider this when designing the pond; Having a shallow pond will make easy prey of your fish for birds, and sloping sides will also make easy prey for the likes of cats and foxes.

A pond net should be used to place over your pond, allowing protection from predators
