More Detailed Pond Liner Reviews

PondHero Pond Liner With Free Underlay

This PondHero Pond Liner With Free Underlay wins top spot for the best pond liner because it 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. It’s the best pond liner for UK gardens.

All Pond Solutions Pond Liner

This All Pond Solutions Pond Liner is a durable LDPE pond liner that is 0.3 mm thick and super strong. It’s a close runner up for the best pond liner available.

The liner comes in a range of sizes and is easy to cut to size. It includes a 25-year warranty provided it is used with an underlay, which you will need to purchase separately. The liner is 200 grams per square metre.

This is a simple to use liner that is flexible and strong. It is reasonable easy to cut and lay it nice and smoothly for an attractive finish.

Flexiliner 4x3m Pond Liner With Free Underlay

This Flexiliner 4x3m Pond Liner With Free Underlay is thin but tough and would not easily be pierced by stones or roots. It comes with a good quality underlay, providing everything you need to get going with your pond. The triple-layer liner has a core of hard-wearing LDPE which is then coated on both sides with a UV/Rot resistant laminate. The inner weave makes the liner highly flexible and easy to fold into difficult corners. It comes with a reassuring  40-year guarantee.

This super flexible liner is thin and light making it really easy for even one person to lay. This also makes it the best pond liner for more intricately shaped ponds, streams and waterfalls.

Certikin 2x3m PVC Pond Liner

This Certikin 2x3m PVC 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.

Polyex 5x4m Pond Liner

This Polyex 5x4m Pond Liner 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.

This is a really heavy-duty liner that would be suitable for a large pond.

Pond Liner Buying Guide

If you are planning a pond, then sourcing the best pond liner is essential. 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.

The best pond liners should always be used with underlay to protect them from sharp roots and stones.

When choosing the best pond liner for your pond, 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.

The best pond liner will also 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.

FAQs

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.
