Benefits of using Fabric Solutions Australia Pond Liner

A pond is generally defined as a body of standing water, either natural or man-made, that is usually smaller than a dam or lake. The technical distinction between a pond and a lake has not been universally standardised. Some say that the definition of a pond relates to depth that light can penetrate and support rooted plants, while other definitions are related to size (footprint) rather than depth or volume. The terms pond, lake and dam can often be used interchangeably.

A pond liner is generally thought to be an impermeable liner, often a geomembrane material that is used for water retention. These impermeable liners are used for the lining of lakes, garden ponds and artificial streams in parks and gardens.

Pond liners need to be protected from sharp objects (for example, sticks, roots and stones) below the liner and from being punctured by any objects in the water body. Liner protection can be provided with layers of sand, concrete, fibre-matting, geotextile and other materials.

Pond liners are manufactured in rolls and strips of liner can be seamed or welded together in a fabrication facility or on site. A number of flexible materials, such as PVC and EPDM, and polyethylene (LLDPE) can have their panels pre-fabricated together in the factory to fit the design shape of the pond.

The edge of the pond liner can be rolled over and secured in a trench or it can be fixed to a vertical wall made in brick or concrete. Box-shaped pond liners can be made for rectangular structures. The vast majority of flexible pond liners available commercially are manufactured of EPDM, butyl rubber or PVC, with LLDPE now being used more and more as it has become more commonly available.

Butyl Rubber and EPDM are relatively expensive but are very flexible, long lasting and mostly fish friendly. PVC and LLDPE are much cheaper but in many cases PVC is not fish friendly or does not have good long term UV resistance.

LLDPE has excellent UV resistance, is fish friendly and flexible albeit not as flexible as Butyl or EPDM.

A good quality pond liner will last many years but many of the lighter gauge (thin) and cheap pond liners have limited life, poor UV light resistance and potentially can kill fish, particularly the more sensitive breds like Koi fish.
