Selecting A Liner

Pond liners are available in different sizes and different materials to fit any pond enthusiast's ambitions. There are three basic types of liners to choose from; pre-formed liners, roll liners and liquid liners. Pre-formed liners come in a variety of shapes and sizes and are very easy to install, however they can limit the creativity of the installation. A second type of pond liner is a flat roll liner, Roll liner can be made of either EPDM (Ethylene propylene diene monomer) rubber, or PVC (Polyvinyl chloride) plastic. Roll liners will conform to any shape pond you may want, simply stretch and fold the liner to fit the shape you have created. These types of liners are sold both in custom sizes, or boxed in pre-cut sizes. Roll liners are available in several different thicknesses, making them appropriate for a wide range of projects. Generally EPDM rubber liners are considered more durable than PVC liners. This is especially important if you're planning on keeping creatures like turtles in your pond which could easily scratch a hole in a thinner liner. PVC liners are lighter and easier to handle, and are an excellent choices for small ponds and patio water features. A third type of pond liner that is available is a liquid pond liner. Liquid pond liners are usually made of Neoprene or EPDM rubber, and are the most difficult of the three to install. In most cases liquid liners are applied over a concrete formed pond, which allows for great flexibility in design, and the most professional looking product. Liquid pond liners are not ideal for cold weather climates due to the damaging effects that freezing and thawing can have on concrete.

There are many similar products available for other industries, primarily roofing, that are NOT fish safe. Roofing materials should never be used in a pond or water garden. Another consideration for pond liners are warranties and guarantees. Quality liners will have a fish safe warranty, as well as sunlight UV protection guarantee..

Installation Tips

Even the best pond liner can perform poorly if it is not properly installed. There are a few things to keep in mind when installing your pond liner. The most important step to insuring a successful installation is protecting your liner from sharp objects and tree roots. The use of an underliner, or fine sand, will help protect your pond liner from puncture. It is also a good idea not to cut your pond liner until you are completely sure you have it the way you like it, and make sure that you have completely filled your pond before trimming of any excess. Once cut, pond liners are not easy to seam. Here is a simple formula for determining the size pond liner you require:

Length of Liner: (Length of Pond) + (2x maximum depth) + (2 feet for overlap)

Width of Liner: (Width of Pond) + (2x maximum depth) + (2 feet for overlap)
