About Pond Liners
Pond liners are used to line the pond to prevent leakages from sharp stones and roots. You can find many types of pond liners in Australia.
The twin ply pond liner is an economical and easy to install. It is usually about 30 ml thick, and comes with a 15 year warranty. This is the best option for those in Australia looking for a first time pond liner. The PPL pond liner is a HDPE/LDPE combination of a pond liner that is best for water containment. It is found to have better strength and more puncture resistant than other liners. Moreover, it also weighs 1/3 the weight of conventional liners, but is stronger.
The reinforced polypropylene pond liner is a polyester reinforced sheet that is actually a superior UV-stabilized polypropylene copolymer with no requirement of polymeric or liquid plasticizers for maintenance of flexibility. As it is a mixture of a strong polyester fabric and polypropylene plies, it provides high puncture resistance. These pond liners are also known as PP pond liners.
The PP pond liner has excellent resistance to low temperature and solar UV and oxidation. There are no liquid or polymeric plasticizers in the PP pond liner; and it also offer low water vapor permeance with water absorption. When using pond liners in Australia, it is better to use underlayment to protect the pond liner. This has to be the same size as the pond liner to make the liner last long.
Pond liners are usually a single piece; however if mistakes occur, there is a liner tape that can be used to connect 2 liners together. This liner tape can also be used to attach the liner under a waterfall filter system while connecting a waterfall liner to the main pond liner in Australia.
