Tank Liners - Fast, Efficient Design & Supply
Waterplex tank liners are installed all over Australia in new and old water tanks alike. In fact, designing and supplying quality tank liners quickly is one of the things we do best. When you need a tank lined, it usually means you have a leaking tank or you want to install a new tank. Waterplex will make sure that you get the right lining solution where and when you need it.
Tank Liner Solutions
Open water tank liners are the most common form of tank liner and are the primary means of waterproofing and liquid containment for :
- new steel water tanks of almost any size
- leaking steel water tanks
- leaking poly plastic tanks
- new concrete for site formed water tanks (for example, Besa Block)
- leaking concrete water tanks
The type of material used depends on the size and shape of the tank, the type of liquid being stored, its end use and the tank location and environment.
Tank Liner Customisation
Open tank liners can be installed in almost any space provided there is adequate access for a person. Remember when designing a water tank that you will need to allow for on-going access for any tank or pump maintenance
An advantage of open liners over enclosed liners is that submersible pumps can be used. Submersible pumps are a good solution where there is limited space outside the tank or if pump noise is potentially an issue.
Obviously all OH&S and confined space precautions and regulations should be followed during installation.
Open water tank liners can be made to waterproof tanks with:
- internal piers
- sumps
- weirs
- walls with step ins or step outs
If you have an unusual tank size or shape call the team at Waterplex on 1300 32 66 70 and we can advise you on the best tank lining solution for you.
