Liner Ponds versus Folding Preformed Ponds


So you've decided to build your very own backyard water garden. You are in the process of actively planning out your design, and you're visualizing the end-result. But have you paused to consider what kind of pond construction you will be using? Do you know what kind of pond constructions exist? The majority of garden ponds utilize one of two types of constructions: a preformed shell, or a pond liner.

Introducing Folding Preformed Pond Shells

Traditionally, preformed ponds are large shells, which are extremely burdensome and difficult to transport. For example, a typical preformed pond kit would come in a box that is 60" x 48" x 24", which is too large for many car trunk sizes.

To alleviate this problem, flexible preformed ponds have recently been introduced by various manufacturers. These folding ponds include built-in plant shelves, are weather-resistant, and are able to withstand extreme temperatures from 0 F to 105 F.

One example of a folding pond, is the one that Algreen distributes (available at Upon closer examination of one of their ponds, one of its greatest features is its textured ridges. These ridges are strategically placed to allow beneficial bacteria to form growth colonies, which significantly reduces algae-buildup in the pond.

Liner Ponds

Liner kits, on the other hand, present many difficulties for the beginner pond gardener. Since every liner pond shape is different, pond gardeners must customize their own pond and ensure that it is level, and that it does not have excessive wrinkling. Therefore, liners are ideal for the more experienced water gardeners because they allow for customizable installations, which consequently promotes greater creativity. However, for the very same reasons, liner ponds also require some extra pre-planning.

Because you can create various shapes with liners, it is possible to construct larger, and deeper liner pond configurations (when compared to preformed ponds). For example, a typical preformed pond at can only hold up to 144 gallons of water. On the other hand, a 10' x 15' liner can be purchased from the same store that can construct a pond that would hold up to 700 gallons of water. However, in terms of cost, the purchase of a EPDM liner is a more expensive option, when compared to the purchase of a preformed pond.

Before making a decision about the pond construction that you require, it is important that you take a moment to consider several variables: cost, labour required, and creativity. It is hoped that by making the proper decision that your pond experience will be all the more enjoyable.
