Choosing the Right Garden Pond Liners

Whether you're building a large commercial pond, or a small water garden, pond liners are essential to making your pond watertight. Without a good pond or water garden liner, the pond will slowly (or quickly) loose water into the ground below.

Flat Liners vs. Preformed Liners

There are two main categories of pond and water garden liners. First there are flat, flexible liners, that are able to bend and conform to any custom shape you can build. The second type are preformed pond liners, which are manufactured into a pre-determined shape out of some kind of flexible liner, hardened plastic or fiberglass.

Flexible Pond Liners

The first and more popular option when it comes to pond and water garden liners, are flexible liners made out of materials like Reinforced Polyethylene, Polypropylene or EPDM Rubber. There are other cheaper materials available, however for the purpose of building a lasting pond, it's best to stick with one of the above mentioned pond liner materials. Each liner has it's own strengths and weeknesses, read on to learn more about each.

Reinforced Polyethylene (RPE) Liners

RPE liners are considered one of the most durable pond liners available, lasting up to 40 years with excellent puncture resistance. In many cases, RPE liners don't even need a protective underlayment because of their higher strength. Another advantage of RPE is they can be produced in very large sizes because of their light weight, up to 60,000 sq ft in a single panel in the case of our Premium Grade RPE Pond Liner. However, a possible disadvantage to RPE liners is that they are slightly less bendable to work with compared with some other flexible liners like EPDM rubber. This is only a slight disadvantage if a pond has a lot of sharp bends and corners that require a ton of folding and pleatingr. Even then, it's usually not that big of a deal, and we still opt for RPE because of it's higher strength and durability. One thing to remember when buying any liner, is that you have to be careful about who you buy the liner from. Not all liners are created equal. Our Premium Grade RPE liners are guaranteed to be fish and plant safe, and come with a 25 year warranty. In addition to ponds and lakes, RPE is commonly used as an indistrial liner as well.

Box Welded Polypropylene Liners

When considering options for rectangular or circular shaped garden pond liners, holding tanks, vegitable filters or other applications, our box-welded polypropylene is an excellent product to consider. Not only is it light and strong, but it is highly UV resistant and safe for fish, plants and humans. In fact, our polypropylene liners are so safe, they are even rated for human drinking water applications. However, the main reason we like Polypropylene is that it can be easily box-welded into 3D shapes at our facility. Box-welding is the process of taking a flat liner and creating a 3D shaped box or cylinder through the process of heat welding the seams (see the picture on the right). The main advantage of box-welding is that all the corners are nice and clean with no folds or wrinkles necessary. If you've ever worked with a flat liner like EPDM rubber and tried to bend it around corners and ledges, you'll know that you will never get it completely flat as numerous folds and liner bunches will be necessary to conform it to the pond substrate. To learn more about, please see the box-welded polypropylene liners in our store.

Rubber Liners

In the past, before RPE liners were fully developed, most ponds were built using 45 mil EPDM rubber garden pond liners. Although rubber liners are quite heavy and much less puncture resistant than our premium RPE liners, they are very flexible which is nice for ponds that have lots of bends, shelves and other features. However, unlike RPE, multiple panels can't be heat welded together. Heat welding is by far the most reliable way to seam a liner - it's possible with RPE, but not EPDM. However, it is possible to join two or more EPDM sheets together with liner tape. Because rubber is so much heavier than RPE, one of the disadvantages of rubber is that it's often more difficult to find and ship large pieces of EPDM due to weight concerns. If you need a large piece, it is usually better to go with a premium grade RPE liner since it's stronger, lighter and more cost effective. To learn more about large liners, please see our page on large pond liners.

A Flexible PVC Pond Liner

PVC Liners

PVC liners are usually the least expensive option compared to other flexible liner materials, but their biggest downside is their lack of UV stability. What that means is that the water garden liner has to be completely buried with no direct sunlight contact, otherwise the liner will begin to break down, shortening the life span. If you do decide to go with a PVC liner, be sure to go with a good quality name. Some of the cheaper PVC garden pond liners may not be safe for fish due to the type of plasticizers used.

preformed pond liner
A Typical Preformed Pond Liner

Preformed Garden Pond Liners

While preformed pond liners are quite easy to install, they are somewhat less flexible with respect to size, shape and artistic freedom since they are purchased in a predetermined shape. While it is possible to find a preformed liner in an appropriate size for a large scale water garden or koi pond, often times they are used more as small garden pond liners. Typically preformed liners are made out of either plastic or fiberglass, which also makes it very difficult to install a pond skimmer. Installing a pond skimmer usually involves cutting a hole in the side of the liner, which usually isn't possible or is much more difficult with a hard shell liner. For more information please see our pages on fiberglass pond liners and plastic liners, pond liners for sale.
