Pond liners fall into 2 categories: flat liners and preformed liners.
Flat Pond Liners
Whether you want to start building a small, medium, or large pond, a flat pond liner is very flexible. And you can bend and adjust the liner to any shape you desire.
Flat pond liners can be made from different materials like Reinforced Polyethylene, Polypropylene, EPDM Rubber, or PVC. These types of pond liners can vary in strength, flexibility, and some materials are better suited for particular pond types and sizes. However, the most common type of materials that are used in flat pond liners is EPDM Rubber or PVC.
– PVC
PVC (Polyvinyl Chloride) pond liners are the least expensive and they are usually quite lightweight and they may include plasticizers, which makes the material very stretchy and flexible. The downside of the PVC liner is that it may not be tear-proof. So the material can be easily punctured, which can cause the pond to leak.
This tendency to leak means that the PVC liner may not be the best choice for ponds that hold a higher water capacity. However, some manufacturers include a polyester weave in the fabric. This helps to reinforce the liner and make it stronger, or you could use an extra Geotextile underlayment for extra protection.
There are 2 important things to keep in mind in relation to PVC liners:
1. PVC liners have small traces of arsenic or other toxins that could be lethal to wildlife and harmful to humans if ingested.
2. The added plasticizers in PVC may also pose a threat to wildlife as these molecules may cause splits and cracks in the material.
PVC liners as not recommended for very cold climates as the material can cause some discomfort to the fish. However, if you are planning on creating a small lily pond or reflection pool, a PVC Pond liner is a very good choice.
– EPDM
EPDM (Ethylene Propylene-ethylene diene monomer (M-class) rubber) is a synthetic rubber and pond liners that are made from this highly versatile material are considered to be the best types of liners for medium and larger ponds.
Liners with EPDM feature thick rubber construction. However, they are also soft and supple. Making them very flexible and can be folded into almost any shape and the liner can be joined together with another liner by using a silicone sealant or pond seam tape.
Pond liners with EPDM are more resistant to punctures and tears. They are a great choice for ponds that contain a lot of plants and have decorative rocks that are placed around the edge of the pond.
The only downside of an EPDM pond liner is that it is heavier than other pond liner materials. You may find it hard to move around especially if you have a large liner, and as the material is soft, an underlayment is required.
– UV and Ozone Resistance
If you want to feature some beautiful brightly-colored Koi fish in your new pond or your garden gets a lot of sun exposure, EPDM liners are the best choice as the material is highly UV and ozone resistant. Liners that are UV and ozone resistant, help to guard your fish against excessive heat. And also stops the liner from deteriorating quickly and losing its flexibility.
– Do You Need an Extra Pond Underlayment?
One of the questions that many gardeners ask in their quest to build a new water feature is ‘do I need an extra pond underlayment or can I put a pond liner directly on the ground?’ Yes, you can put the liner on the ground by itself.
However, if the liner does not come with an underlayment, there is the possibility that there might be sharp stones in the ground where you want to build your pond which can cause a puncture in the liner and it will start leaking water.
An extra pond underlayment will protect your liner from getting damaged. It can also smooth over any uneven ground and sharp rocks or stones, and will help to maintain the durability of your liner over the long term.
Preformed Pond Liners
If you prefer a no-mess-no-fuss approach to pond building and do not want to wrestle with a heavy flat liner, or you just want a small pond that you can set-up anywhere, either outdoors or indoors, then a preformed pond liner is the pond liner for you. A preformed pond liner takes all the hard work out of installing a pond. Or you could invest in an all-in-one DIY pond building kit.
Preformed liners are already designed in a particular shape and they can be made out of hardened plastic or fiberglass. The downside of the preformed liner is that their predetermined shape. It does not allow you to change its shape unless you dig the whole liner out and use a flat pond liner.
Warranty
The length of the pond liner’s warranty is also important. Some manufacturers offer you more durability and product value for money. However, having a warranty that covers your liner for a considerable amount of time like 10, 25 years or more, gives you extra peace of mind. An extended warranty covers the liner in case it does not meet up with your expectations or it gets ripped or starts to leak.
Another important thing to consider is that some warranties have limitations. It is a good idea to read the fine print to find out what the warranty covers and what it does not cover. Some manufacturers do not readily display their warranty information next to the product. So you will have to request the details. Before you purchase a pond liner, visit the company’s website.
