Inexpensive Pond Liner Ideas Are They Worth It

Those thinking about installing a new pond in their garden may be looking at ways to cut costs for the project. While there are some ways to save money on your pond project (such as limiting the number of plants or decorative rocks you use), Aquascape does not recommend using a cheap pond liner substitute.

There’s no shortage of inexpensive pond liner ideas out there. Today we take a look at a few of the cheap backyard pond ideas for pond liners, and the issues that you could run into by using them.

Polyethylene Pond Liner 

One popular alternative to EPDM pond liners are polyethylene pond liners. While this substitute might seem appealing at first due to its cheaper price point than EPDM, it’s important to realise the downsides. 

  • Polyethylene pond liners are pretty thin, meaning there is generally a higher chance of punctures than with thicker, sturdier materials. 
  • Polyethylene pond liners tend to last for a shorter period of time than EPDM liners. 

This means if you use polyethylene as your pond liner, you will likely need to dig up your pond to replace the lining sooner (and more frequently, if you choose to use it a second time) than if you used an EPDM liner.

PVC Pond Liner

Another cheaper option for pond liner is PVC. While PVC can be alright to use for small, simple and shaded ponds with few features, it doesn’t fare so well when used for larger or more complex projects. Large rocks can damage your PVC pond liner, as can trampling from furry paws! PVC does not do well with high traffic, and as such, shouldn’t be used for swimming ponds or anywhere that kids and pets will be looking to take a dip. Many PVC pond liners are also not UV resistant, and can begin to become brittle when exposed to the sun for long periods of time.

Tarpaulin

Those looking for inexpensive pond liner ideas might be eyeing off the camping tarp, wondering if it can be used to line your pond. Sadly, the truth is that most tarpaulins aren’t designed to be used as a pond liner, and can have a fair few downside. Aquascape recommends against it being used as a pond liner substitute. Tarps are often water resistant and not waterproof, so you could find your pond leaking in a short amount of time. Rather than trying to save your money by using a tarp as a pond liner, you should look for other areas of the project where you can cut a few costs without risking quality and durability.

What do we recommend?

So, what type of pond liner is best? At Aquascape, we recommend using Firestone EPDM pond liners. These liners are: 

  • Fish-safe 
  • UV-resistant
  • Flexible 
  • Come with a 20-year guarantee

We stock Pondgard and Geogard EPDM membranes in our online store, which are both specifically designed for pond applications. Pondgard and Geogard are easy to install with no special tools required for the process.

When it comes to pond liners, there’s no substitute for quality. Having your pond spring a leak because you chose to use a lower quality pond liner can be a frustrating fix. We recommend Firestone EPDM pond liners due to their durability and reliability.

If you’re looking to save money on your pond project, consider cutting down on the number of decorative rocks or plants that you have as part of your feature. You can always add these items in later, if you so wish.
