AquaMark Liner material is a food grade (AS/NZS 4020 potable water certified) supported liner material suitable for use in a wide range of water and effluent containment and storage applications.  Ideally suited to prefabrication of liners for transport to site and installation with minimal skilled labour required at the installation site.


AquaMark Liner is lightweight and flexible & extremely tough.  Equally suitable for dam and pond lining as well as a highly durable tank liner with a 20 year UV warranty and high tear strength, AquaMark Liner provides a lining solution in agricultural, industrial and mining applications.



  • 400gsm or 480gsm Polypropylene - light weight enabling large liners or liner sections to be prefabricated for speedy installation
  • BPA Free
  • AS/NZS 4020 approved for contact with potable water - ideal for grey, black and potable water storage applications.  One liner material suits most applications
  • Environmentally friendly Polypropylene - both the manufacture and eventual disposal of the 100% recyclable material ensures minimal impact on the environment with no chlorine or heavy metals in the production of the product
  • Tested to 39m waterhead (400kPa)
  • Aquamark® +480 complies with 3.6.1 of AS2304- 2011 (water storage tanks for fire protection systems)
  • High strength material with durable layered technology supported by high strength woven base material
  • Watertight joints are achieved utilizing double weld heat welding
  • Conforms to the seepage requirement of less than 0.1mm/1cbm per day
  • Generally, any liquid with a pH in the range of 6-8 is able to be in contact with Aquamark. pH of 4 & less is not suitable. Between pH 4 & pH 6, you will need to seek advice from us as to suitability.  If the storage requirement is above pH 10, Aquamark is not suitable. Between pH 8 & pH 10, you will need to seek our advice.

  • Agricultural - dam liners, effluent and wash down containment ponds, tank liners, channel lining
  • Viticulture - contain grape marc & other waste
  • Horticulture - dams & ponds for water supply
  • Industrial - bunding liners, effluent ponds, water storage and containment
  • Building and construction - storm water containment liners, water storage, tank liners
  • Aquaculture - fish and crustacean breeding ponds, bio fuel production ponds
  • Lifestylers - store water - less stress in summer for stock water & firefighting
  • Forestry - fire fighting water storage
  • Biogas Storage

So long as there are no sharp objects (rocks, roots, etc.) in contact with the liner, a Geomembrane underlay should not be required.


In addition to Aquamark, we are able to source a wide range of alternative living material through our supplier network.

This has enabled us to line fuel farms, storm water containment and water detention systems, and effluent ponds that required a thicker material to meet local Council requirements .


Please do not hesitate to contact us and we can source a material that will suit your project.
