Best Pond Liner – Buyer’s Guide

If you’re a little unsure of what to look for when finding a pond liner then we have listed some of the top features for you below. Our buyer’s guide intends to help you purchase the best pond liner that is going to be suitable for you and your garden.


Pond liners are available in different sizes. Again the size that you choose is dependent on the size of the garden that you are working with. For a smaller garden, a minimal pond is going to fit in a lot better with a more compact look. For a larger garden, you have the flexibility to choose a larger sized pond.


Now plastic pond liners can come in all different shapes, the shape that you choose depends on what is going to work the best with your garden space. Some common shapes of pond liners may include round, egg-shaped, oval, rectangular or free form.

Some pond liners come in a roll with the versatility to be moulded into whatever shape you would like for your pond.

The Type of Plastic

Different types of plastic are going to fare differently against the weather. A pond liner is going to be exposed to all different weather conditions, however, the sun or warm weather is likely to cause the most damage. A pond liner with UV radiation is going to be stronger and less likely to crack, leak or become brittle. It should also be capable of stretching when the temperature changes.


The thickness of the pond liner is very important too. They are available from around 0.35mm thick to 0.75mm thick. The thicker pond liner is likely to last a little longer as they are more likely to withstand wear and tears. However, if you wanted a smaller pond in your garden then a thinner liner may suit your needs.

Material construction

Available on the market you can now get pond liners that are constructed using different materials. You may find some to be stronger and more durable than others. The first is PVC, as an inexpensive option, it is very commonly used in pond liners. It is slightly heavier than LDPE however it is a stretchy type of fabric so there is more flexibility in regards to the shape of the pond you can create.

Another common material is LDPE, which again is a popular material to be used in pond liners. This material is great for wrinkle-free, tight-fitting bases and it is also tear-resistant. EPDM is another material. This tends to be the strongest material out of all that we have mentioned. Not only is it tear and puncture-resistant it is also a lot more stretchy and flexible to give you greater versatility with how you can work with it.


You will ideally want a pond liner that is flexible so that there is more versatility to mould it to the alignment of the desired shape of your pond. A liner that is easy to manipulate into a specific shape is going to be a lot easier for you to use.


Before laying down your pond liner you will require some underlay which will add protection to whatever conditions that you pond liner might face from the ground below, such as sharp stones and also the weight of the water that it is capable of holding.


Different types of pond liners are available for a range of prices. The material and size of the pond liner are going to influence the price that it retails for. The most common types of pond liners are made from PVC or rubber which are ideal options for those wanting to start creating their pond from scratch as they are both good quality materials at affordable prices.

Frequently Asked Questions

How long is a pond liner going to last for?

Typically a PVC or rubber pond liner is going to last an average of 20 years before deteriorating in quality and needing to be replaced. A pond liner is only going to last for this length of time if you take the right steps when installing it in the first place. For example, using the correct protective underlay and then also maintaining your pond correctly for the duration of the time that it is in place. This is going to ensure that it lasts for a decent length of time.

What kind of pond liner is best?

Pond liners that are made from rubber tend to be the best option as they are a lot stronger and flexible which makes them much easier to work with. A rubber liner is also more likely to last you a lot longer too as it is less prone to tears and breaking. They also tend to be an inexpensive option too. However, you will find that PVC liners are also very popular and this is because there is a slight stretch to this material which gives you the flexibility to create the shape of the pond that you want and it is inexpensive too.

How do I maintain my pond liner?

If a pond liner is maintained correctly you will find that it will last a long time before the deterioration in quality. Failing to maintain the cleanliness of your pond liner is more than likely to result in algae growth which can spread very quickly. Ensure that you scrub the sides of the pond liner and also any rocks that are in it too as this will help to loosen any algae that are starting to grow. If you have a pond pump or filter too these should be cleaned thoroughly. Ensuring that you are following these steps will help to prolong the life of your pond.
