Best Pond Liners – Buyer’s Guide
Whether you are constructing your first pond or your tenth, a liner is an essential part of the pond. The right liner will lend strength and integrity to your design.
With so many options and materials available, choosing the best one can get pretty confusing We’ve created this guide to help clarify the vast array of options available to you, so you are able to make an informed decision when purchasing a liner.
Do I Really Need to Purchase a Pond Liner?
During the excavation or hole digging phase of your pond project, you may be tempted to skip using a liner. You do not want to skip this imperative step. The pond liner is a waterproof fabric which will keep your pond filled with water, instead of it just leeching back into the earth. It also protects any fish or plants that have made their home there.
Most liners are attached sheets of fabrics. These joined areas, or “joints,” are sealed in the factory to ensure their strength and durability. Purchasing a liner meant strictly for ponds is an essential part of ensuring your pond stays beautiful, safe, and fresh for years and years to come.
Key Factors to Consider when Choosing a Pond Liner
There are several important factors to examine while searching for the perfect pond liner.
The type of exposure your liner will be under is an important point to think about. Assessing whether your new liner will be exposed to the sun’s harmful UV rays is an excellent place to start. UV rays aren’t just harmful to our sensitive skin. In many cases, the liner will be covered with cement, so this isn’t as much of an issue. If you live in a particularly sunny area, this may be of more importance to you and your pond.
Some of the materials that liners are crafted from can be prone to disrupting the various forms of flora and fauna found within your pond’s ecosystem. PVC liners fall into this category. If you’ll be filling your pond with fish or flowers, closely examining the materials constituting the liner is crucial. Additionally, some liners contain arsenic, which is extremely deadly to plants and animals no matter how low the amount.
You need your liner to be flexible so that it can be properly shaped to align with your pond or similar water project. Depending on the materials that your liner is crafted from, it will have varying degrees of malleability. Some of the more popular pond shapes like kidney bean shaped or freeform will require a liner that is easy to manipulate into the curves and crevices presented.
What are the Different Materials Available?
Let’s take a closer look at the components that pond liners are crafted from.
Reinforced Polyethylene Pond Liners
Reinforced Polyethylene Pond Liners, RPEs, are quite possibly the most durable type of liner. They are extremely solid and resist punctures and tears beautifully. This version is thinner than others and can be welded together using heat methods. RPEs are able to last over 40 years, which is an extremely long time as it pertains to liner lifespans.
RPEs are easier to pack and install thanks to their thickness. They are also lighter. Due to their thin characteristic, you will need to utilize an underlayment. This version is also safe for plant and animal life and costs less than other materials.
On the downside they aren’t very resistant to UV rays. As such, RPEs are best used in areas that aren’t subjected to much direct sunlight. You may be able to avoid this with cement or extra soil.
Ethylene Propylene Diene Monomer Pond Liners
Ethylene Propylene Diene Monomer, EPDM, is heavier making it more difficult to ship and handle. These liners are easily folded, especially around corners, which is due to its high flexibility degree. EPMS are safe for plants and animals as well.
Unlike RPEs, EPDMs cannot be heat welded together, but you can attach them with tape. This particular material is not very resistant to punctures, so you’ll need to use an underlayment with this version. They are extremely UV resistant though.
Polyvinyl Chloride Pond Liners
Polyvinyl Chloride, PVC, is heavier than RPE but slighter than EPDM liners. They are the least expensive version available. Some of these liners may contain trace elements such as arsenic, so they shouldn’t be used for fish or plant-filled ponds if they contain these kinds of ingredients.
PVC liners often have added in plasticizers to increase flexibility, which may tend to split and crack. This makes them a dangerous hazard to many different types of wildlife. They are fairly easy to lay down and fold and fall in the middle of the puncture resistance spectrum when compared to RPE liners and EPDM liners. They are the least UV resistance and do not last nearly as long as other versions which may also make them undesirable for many products.
Calculating the Right Amount of Liner Needed
To figure out the size of lining needed, you’ll just need to perform some simple math equations. You can use these calculations in inches, feet, yards, or even meters. These equations will also include the overlap needed for the top lip portion of the pond.
• Necessary Liner Length = Length of pond + 2(depth of pond) + 2
• Necessary Liner Width = Width of pond + 2(depth of pond) + 2
Underlays are a crucial piece of the pond puzzle. They will be laid down before your insert your liner. The purpose of this item is to add protection from both above and below pressures that could harm the liner. From sharp stones that could puncture or tear the liner to the weight of the water filling the pond, underlining is an imperative part of ensuring your pond’s structural integrity.
Underlays will also guard against dangers such as plant roots which continue to grow sight unseen beneath your pond. These roots may not be an issue currently, but eventually, they can become a thorn in your pond’s side, literally. An efficient underlay will act as a barrier to prevent such problems.
Thinking about what type of pond you want is the first step in determining which lining will be the perfect fit. If you plan to have a peaceful Koi fish pond, steer away from any liners with dangerous trace elements like arsenic. If your pond is very large, using RPEs may be your best bet, since they are easily welded together using heat. Understanding your needs and comparing them with each type of liner should make it much easier to find the best liner for your pond. Don’t forget to leave us a comment with your thoughts and tips.
