Ponds are small water spaces that provide beauty and calm to their surroundings, whether large concrete constructions or small private gardens. Even the Romans, Egyptians and Chinese of the ancient world loved to decorate their gardens with attractive ponds.

The most important task while building a pond is to lay a Pond Liner, just like laying a foundation for a building. A natural lake or pond has dirt, rock and silt at its bottom. A Pond Liner helps prevent the pond water from penetrating the soil, making the soil silty.

Pond Liners come in different options. The first choice is between preformed and custom-made or flexible. Preformed liners are suitable for small garden ponds. Preformed Pond Liners are quick and easy to install. Flexible liners are suitable for medium-sized ponds. Flexible liners are made of natural materials like rubber and clay, as well as synthetics such as PVC liners.

Installing a preformed Pond Liner requires creating a hole suited to the space of the pond. But installing flexible liners requires checking whether any sharp objects will penetrate the liner.

Preformed Pond Liners made of plastic are strong and not likely to leak. They are difficult to fit, due to their varying shapes and depth sizes, and are suited to small ponds. Such ponds are usually expensive, with high delivery charges. Flexible liners include rubber products like butyl rubber, EPDM (ethylene propylene dyiene monomer) rubber, and clay like sodium bentonyte clay. Synthetic plastics include P.V.C. (polyvinyl chloride), polyethylene (a thermo plastic) and Ultra Guard (polymeric alloy).

The primary advantage of flexible Pond Liners is that they are easy to transport. They are not affected by limits of size or shape. The materials can be molded into the pond shape of your choice. It is easy to make adjustments. There is a variety of material to suit every need. The pond will look natural as it blends with the landscape.

Synthetic rubber is most versatile. Called EPDM, it is economical, durable and easy to install. And really flexible. Flexible plastic liners such as PVC and HDPE are available, but not as effective as rubber liners.

With the advent of garden pools and preformed pool liners, all the hassles of concrete and other raw material are saved. Heavy-duty Pond Liners are available with long-term guarantees, and sell for less than $1 per square foot. Large ponds require a large Pond Liner that is safe for fish and plant life, inexpensive, easy to install, and durable to last over 20 years. Polyethylene is suitable for such ponds.

Pond Liners are available in black, and U.V. protected. Many people install pre-liners to provide an insulating layer between the soil and Pond Liner. Ultimately, to select a Pond Liner, a number of criteria must be considered such as size, quality goals, budget, property value, and wildlife.
