What is a pond liner?

A pond liner is a tarp-like structure that can be used to cover the bottom of your pond. It’s made with water-tight material that prevents water from seeping out into the earth.

It helps the pond hold water, gives it structural integrity, and improves the aesthetics.

What are the different types of pond liner?

There are different types of pond liners available based on your needs.

Pre-formed pond liner

If you want a small pond and don’t want to spend a lot of effort on the work, a pre-formed plastic liner is available.

This is made from a mould of plastic or fiberglass in the shape of a pond. It’s suitable for a small pond with shallow depth.

You need to dig a hole of the same shape as the pre-formed liner to hold it in place.

The drawback of using this type of liner is that you don’t get to be creative or customize it as per your needs. And it’s suitable only for a small pond.

Flexible pond liner

These are the more commonly used pond liner that can be placed in a pond of any shape.

They are available either as plastic or rubber material that can be cut and fit for any sized pond. They can be expensive or cheap based on the material. And the material also determines the durability and flexibility of the pond liner.

Do you need a pond liner?

If you have a pond, you’re going to need a pond liner. Otherwise, you’ll be troubled by problems like loss of water and erosion of the pond.

If you have fish and plant life in the pond, the liner will help keep them protected and thriving.

How to choose the best pond liner

The pond liner can differ based on the type of material used. But there are also several other factors that you can use to choose the best pond liner for your pond.


The pond liner will be exposed to the sunlight, ozone, water pressure, and fluctuations in temperature.

All these factors place lots of stress on the pond liner. So you need to pick one that gives you good durability and lasts a long time without need for replacing.


The thickness of the pond liner impacts the durability. But the thicker the pond liner the heavier it can get. And it can also be difficult to install.

The thickness of the pond liner is measured in mils. One mil equals one thousandth of an inch.


The most influential factor of your pond liner is the material used to construct it. The durability, thickness, and cost are dependent on the material.


PVC stand for polyvinyl chloride. This is the lightest pond liner material you can find. It’s inexpensive and easy to install in your pond.

But it’s quite thin measuring just 20 mils. This means it’s not very durable and has a short lifespan. It could be punctured by rocks, roots, animals, or when working in the pond.

You also need to be careful not to pick PVC that contains arsenic or other harmful chemicals. These can affect the animal and plant life in the pond.


LDPE stands for low density polyethylene. This is the material you find being used as tarps in agriculture and construction.

It is quite flexible even though it has a good thickness of 40 mils. It’s better than PVC but it has its drawbacks.

It’s not very strong and durable compared to some other types of pond liner material.


EPDM stands for Ethylene propylene diene monomer. This is a synthetic rubber material that you find used in roofing material or automobiles.

This is the best pond liner material you can get because it’s very durable. It’s puncture resistant and UV stabilized. The thickness of this material is about 45 mils.

It’s also quite safe for the fish and plants in your pond.

This material has a good warranty of 20 years or more which tells you about it’s durability. This does make the material expensive compared to the others. But you get high-quality in exchange.

It’s quite thick which makes it heavy and difficult to install compared to the others.


The size of the pond liner is determined by the size of your pond. You can get a pond liner from 5×5 feet to 35×35 feet based on your needs.


Check that the pond liner has material that is good for the environment. It should not contain harmful chemicals that can impact plants and fish in your pond.

Some material like PVC might contain traces of arsenic that could be harmful.


The benefit of using a pond liner is you can help shape it as per your pond. That’s why pick a material that makes it easy to adjust it to your pond and crevices.

Protection from the sun

You need to choose a pond liner that has durable material. This includes protection from the UV radiation and ozone.


A company that is confident of its products provides a good warranty. You could get pond liners that come with a 10, 25 year or longer warranty.

Do remember to read the fine print of what is covered before buying the pond liner. Some will protect you in case the liner material gets ripped or starts to leak.

Precautions when using a pond liner

You should not use the pond liner directly on the base of your pond. Use a underlayment on the base instead.

This underlayment acts as a protective layer between the pond liner and the ground. This underlayment could be sand, an old carpet, or a layer of newspaper.

This material prevents roots from penetrating through the ground and protects damage from the rocks. It also gives protection when animals move in the pond. Or when you’re doing some work in it.

When you’re placing the pond liner, make sure the area is smooth and there are no sharp objects on the surface. Lift the pond liner and place it gently instead of dragging it across the ground. That increases the risk of puncturing the liner.

If the pond liner is heavy and you’re struggling, you can get the help of more people to place it right.

How to use a pond liner

Before using the pond liner, you should find out how much area of the pond needs to be covered. You can either dig the pond and then find out the measurements or just do it on paper beforehand..

You need to know the length, width, and depth of your pond to calculate the size of the pond liner you need.

The length of the pond liner = Length of the pond + 2 x (Depth of the pond) + 2

The width of the pond liner = Width of the pond + 2 x (Depth of the pond) + 2

This calculation will give you enough pond liner to cover the pond and overlap the sides as well.

If you have a small pond or a tight budget, it’s OK to go for a pond liner with PVC material. But if you have a large pond, EPDM is the best material you can go with.

You should place the liner over the base of the pond and keep it in place with round stones. Then fill the pond with water and smooth out any wrinkles in the liner. You can also place colorful rocks along the outside of the liner to secure it.

It’s important to have the right installation of the pond liner otherwise you risk issues like soil erosion. Or leaching of the water into the ground.

Maintaining your pond liner

Once you’ve set up the pond liner, it’ll keep your pond and fishes comfortable for a long time. But you do need to sometimes do some maintenance on it.

The best time to do this maintenance would be spring where you can clean the pond and the liner. Then it’ll be ready for a good looking pond by summer.

You should clean up the pond and liner of debris that may have fallen in the pond. Do clean up the dirt and algae that may have grown in the pond. You could use a pond vac or a net to get rid of these.

During summer, the water level of the pond would reduce due to the heat. It’s good to keep it filled up as this reduces the exposure to the sun and UV radiation.
