Exploring Your Pond Liner Options


Pond liners are an essential element of having a beautiful and problem-free backyard oasis. When the right type of pond liner is chosen, a seal is created between your pond and the otherwise damaging elements which surround it.

Skipping out on the expense of a liner may seem worthwhile to some. However, the costs which will arise from erosion, leakage, and contamination can easily end up costing you more money than you would initially save.

Keeping Your Pond Beautiful, Clean, and Crystal Clear

A pond liner plays a key role in keeping your pond looking gorgeous for several years with little maintenance. Some of the benefits include:

  • Keeping water in your pond so that you do not need to continually refill your pond
  • Maintaining the structure and shape of your pond (over time, your pond can lose shape and depth as the soil surrounding your pond mixes with the water)
  • Keeping your water clear and beautiful
  • Helping keep contaminants out of your water (this ensures that the pond is healthy for both plant and animal life)

Your Pond Liner Options

Water Garden at www.water-garden.co.uk are specialists in the supply of high-quality pond liners and offers a variety of different types of liners to meet your specific needs and challenges. Below, we will talk about your pond liner options, what benefits they bring, and what potential challenges or drawbacks they may present.

Butyl Pond Liners

Thickness: 0.75mm

Best Usage: All aquatic projects

One of the most well-known names in the pond lining industry is Butyl. The liners produced by this company have set the standard for pond liners and how they should be. This type of liner is perfect for any aquatic project you may have, from small ponds to large lakes and any kind of water feature. Butyl easily moulds to the shape of any pond and delivers superior results.

The problem with Butyl liners is the cost. If you can afford to have a Butyl liner, it certainly is the way to go. Most liners are also backed by a guarantee ranging from 10 to 25 years.

PVC Pond Liners

Thickness: 0.5mm

Best For: Smaller ponds which can be accessed from the edge, as placing pressure on the PVC liner (i.e. bracing yourself with your hand on the liner or walking on it) can cause a hole to develop

One of the most common types of pond liners is the PVC pond liner. This type of liner is the most cost effective option and, when used in the right conditions, can last a fairly long time.

There are a few issues which come with the installation and maintenance of this type of liner, however. For homeowners who are planning on building a pond themselves, they should wait for a warm and sunny day to install a PVC liner. This is because this type of liner can be difficult to work with and fit successfully if it does not have heat to help mould it.

Another drawback is that it can puncture easily. The good news is that repairing a PVC liner is quick and fairly straight forward, but it does still require draining and then refilling the pond again.

Lastly, PVC can be quite brittle in cooler temperatures. If you are in an area where it regularly dips below 8 Celsius, then another type of liner may be better. This type of liner can also only be cleaned when the temperature is above 8 Celsius.

Greenseal Pond Liners

Thickness: 0.75mm

Best Usage: Ponds of all sizes and water features. Suitable for ponds for fish and wildlife

One of the more innovative types of pond liners available in the UK is Greenseal pond liners. Workable in all temperatures and easy to maintain and repair, this type of pond liner feels and looks like rubber. It is versatile, can be used in ponds of all sizes, and folds and creases extremely well.

The main drawback with this type of liner is the cost. What you get for investing a bit more money into this type of liner, as opposed to a PVC liner, however, is better quality and longevity.

Firestone EPDM Pond Liners

Thickness: 1.02mm

Best Usage: Large ponds and lakes

In terms of strength, Firestone EPDM pond liners are the champion of all pond liners. Being significantly thicker than other liners on the market, this type of liner can only be punctured by extremely sharp objects. It is elastic and is able to take the pressure placed on it by blunt objects.

The main issue with Firestone pond liners is that it does not fold or crease very well. Because of this, this type of liner is not well recommended for those who are building a small garden pond. It can, however, work very well with water features.

What about Preformed Pond Liners?

Another option available to pond lovers is a preformed pond liner. There are a lot of advantages which come with this type of liner, such as it being easier to install and very durable (most are made of plastic or fibreglass).

Why preformed pond liners have not grown in popularity in the pond industry is because they are incredibly restrictive. The liner you order is the shape which your pond will be. This means that you cannot choose the size, the shape, or the depth, so you may not end up with the pond you had been dreaming of. There are also not a large variety of designs or shapes to choose from.

The final option which one may want to consider is what is referred to as box welded pond liners. While not every pond provider is able to create these bespoke liners, box liners are perfect for almost any type of pond. Coming in a thickness of 0.75mm or 1mm, these pond liners are made to measure, meaning that you are left with a seamless pond with no folding and no pleats.
