What Is The Best Pond Liner?
More Detailed Pond Liner Reviews
This pond liner comes in a range of sizes and offers great value for money. The product is sent with a matching amount of underlay. This is essentially a weed resistant fabric which will help extend the life of your liner.
The sellers sent me lots of this, so it would be enough to double over for some extra protection, too. However, it won’t protect the liner from sharp stones, so you should remove these before laying. Ideally, your pond should be lined with a layer of sand before using this product to get the maximum life.
The pond liner has a UV resistant coating to make it extra durable and is guaranteed for 40 years. It is impressively thick for the price, easy to cut to size and would be suitable for a moderately sized pond.

This super flexible liner is thin and light making it really easy for even one person to lay. This also makes it suitable for more intricately shaped ponds, streams and waterfalls.
This thick durable pond liner is UV and cold resistant. It is 0.5mm thick and tear and root resistant. It comes with a 10 year guarantee or a 20 year guarantee when used with a Heissner underlay.
The material is thick yet easy to lay, though it is easier to handle with two people.
This is a strong, durable and flexible pond liner that is guaranteed to last for at least 25 years when used with an appropriate underlay. The liner consists of a woven inner core that keeps it flexible between two outer layers that are UV stabilised and rot resistant. It is reversible with one side being black and the other brown.

Pond Liner Buying Guide
If you are planning a pond, then getting the right liner is a key factor. You want something that is tough and durable, but also light and flexible so you can create a nice shape and smooth finish. Also, having done the hard work of digging out a pond, you want to be sure that the liner you use will last many years.
Flexible liners mean you can make a pond of any shape you want, as well as other features such as streams or waterfalls. Using a flexible liner means you can make a nice natural looking pond relatively easily. In addition, flexible liners are usually dark in colour and therefore become invisible once the water is added and this creates a nice illusion of depth.
Pond liners should always be used with underlay to protect them from sharp roots and stones.
When choosing a pond liner, obviously durability is an important factor. Most liners are made from fabrics that are tough enough to last for decades. Many are also UV stabilised. However, the liner will only last many years if the preparation for your pond has been done well. Always remove sharp stones that could pierce the liner and use an appropriate underlay to prevent roots from breaking through.
You also want your pond liner to be nice and flexible, so you can create a natural design. Luckily, modern liners are made from materials that are surprisingly light and flexible without compromising on durability. This means you can easily create more intricate shapes and neat corners.
Flexible liners come in a range of materials including PVC (Polyvinylchloride), HDPE (High Density Polyethylene), EPDM (Ethylene Propylene Diene Monomer) and Butyl Rubber. These are all flexible and strong materials that will help you create a natural looking pond that will last for many years.
How do I choose the right size liner for my pond?
The following formula will help you choose the right size liner for your pond
Liner length = Max Excavation Length + twice maximum depth + 1m for overlap
Liner width = Max Excavation Width + twice maximum depth + 1m for overlap
Remember to measure the length and width at the longest and widest parts. Also, remember to include enough liner for overlap when you make your purchase. The overlap provides extra material to cover any margin of error in calculations as well as for edging.
Can I use a rubber liner for my pond?
Butyl rubber pond liners are very hard-wearing and reasonably easy to work with. However, they are very thick and heavy. Also, rubber liners are toxic to some animals and so may not be suitable for a Koi or wildlife pond.
