When first installing your garden pond, there are a few different important decisions you must make. Do you want fish and plants? Are you going to add fountains and waterfalls? How many gallons are you going to shoot for? The list of concerns goes on and on, it seems. One of the most important things to consider, though, is what pond liner will best suit your setup and needs. In today’s highly saturated market, it can be a bit of a blur to attempt to decide which liner will best benefit your pond. Here is our guide to the best pond liners on the market today and what situations they best apply to.

A Bit of Background

Pond liners are geomembranes added after the initial hole for your pond is dug to seal the area. Generally, the liners prevent water from leaking and keep your pond looking cleaner and clearer than a clay or dirt bottom since there is little sediment getting into the water, though it is not mandatory or vital for a healthy pond in most cases. Pond liners are relatively inexpensive and can last quite a while when properly cared for, making them a good place to invest a little extra money if possible to help ensure access to a high-quality product.

Liner or Pond Armor?

Traditional Pond Liners

If you are going to choose to use a liner, you should understand what exactly they are made of. Pond liners are typically made of one of three different materials: reinforced polyethylene, ethylene propylene diene monomers, or HDPE. For those looking to DIY a pond at home, reinforced polyethylene is the way to go. This lightweight product is easy to install and quite moldable with separate sheets being easily molded together. Ethylene propylene diene monomer-based liners have been the industry standard for quite some time due to their flexibility and UV resistance. Unfortunately, they are easy to tear or puncture, so they do require a bit of maintenance. HDPE liners are a hybrid product that requires professional installation but looks amazing and is incredibly durable, making it more expensive initially but a good investment due to their lasting abilities.  Of course, other products do exist made of different materials but these three comprise most that you will find today.

Pond Armor

Most people choose to use a liner when constructing a pond since it is generally thought to be much easier. If you are going to opt for a liner-less pond, you need to make sure that your surface is suitable. Pond Armor can be applied to:

  • Concrete
  • Cement
  • Shotcrete
  • Gunnite
  • Tile wood
  • Stone
  • Metals: steel, aluminum, copper, cast iron, brass
  • Rock
  • Some plastics
  • Fiberglass

Top 7 Best Pond Liners

1. Pond Armor – Non-Toxic Pond Shield Epoxy Paint

The Pond Armor Non-Toxic Pond Shield Epoxy Paint is a bit of a different spin on a traditional pond liner. This product eliminates the unsightly creases, lines, seams, and texture that comes along with using sheet-style liners and grants users the freedom to create ponds in any shape or size with ease. The unique formula can be applied much like traditional paint. The brand recommends using a squeegee, brush, sprayer, or other painting tool based on your own skills and preferences.

Questions and Answers About Pond Liners

Can you cut pond liners to better fit smaller ponds, waterfalls, and other water fixtures?

For the most part, liners are able to be trimmed to allow you to customize the size to suit your needs. To do this, use a sharp blade or specialty shears to carefully cut off the unwanted portions of the liner. If the liner has a rough edge after being cut, you can usually gently sand the edges to remove any texture or sharp pieces, though you should double-check with the manufacturer’s information to ensure that it is safe to sand the product before attempting any alterations. A little tip: keep any trimmed off pieces in a safe storage place in case of emergency repairs or to use in other projects; these take quite a while to degrade in landfills so reusing them when possible not only helps you get more bang for your buck but also keeps the planet looking nice, as well!

Can you use these pond liners for food gardening purposes?

Many people plant food alongside their pond and some have figured out ways to seamlessly integrate the two hobbies but, unfortunately, many pond liners contain rubber which can release chemicals into the food and make it unsafe to consume. Carcinogens are known to be released by rubber when it gets heated; these cancer-causing chemicals can wreak havoc if ingested so it is best to keep your garden separate from your pond and use alternative products that are food safe to grow such plants. Aquatic plants do just fine with rubber liners since you are not consuming them, though. Instead of planting food items in the pond liners, try doing some creative landscaping to create a garden area next to your pond! It will look stunning and keep you completely safe!

How do you clean a pond liner?

When you clean your pond, the liner is usually included in the process. When cleaning your liner, remove any fish from the water and choose a pond safe cleaner like vinegar or a specialized commercial product. Follow the directions on your commercial product or pour a bit of vinegar into the water and scrub the liner gently to remove any debris. Drain out the water and rinse the area well before reintroducing the fish. Alternatively, if you do not want to drain your pond you can quickly clean it by simply wiping up any debris and removing leaves and other odds and ends from the water, though on occasion you should definitely fully clean everything to keep your pond looking nice and your fish healthy. There are tons of helpful resources for cleaning tutorials online so do a bit of research and find one that suits your set up and you will be all set!
