Pond / Dam Liners

Process from excavation through to install & finally, after a couple of years - looking stunning!

Made in New Zealand - Our liners are tough & easy to install


The liner will be made using an Australian textile, Aquamark®.  Aquamark® is a scrim reinforced polypropylene coated fabric, specifically designed for a wide range of water and effluent containment and storage applications. Aquamark® is light but strong, as opposed to the much heavier traditional pond lining material.  This reduction in weight makes it a much easier & faster liner to install.  In most cases, the entire liner is made by us & shipped to site - this eliminates weather related stoppages & potential contamination into the welding joins.



Pond Liner Construction

  • 20 year warranty against UV degradation
  • 400gsm or 480gsm Polyproylene - 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.
  • Aquamark® 400gsm (0.5mm thickness)   or   Aquamark® 480gsm (0.65mm thickness)

If you do need a thicker textile for your liner, we have access to other textiles which are thicker.  Please email us to enquire.


Measuring your liner

Measure following the red line in the diagram below

  • Trench - the bigger the dam, the bigger & wider the trench will need to be - speak with your contractor
  • Slope of walls - usually around the 1:3 ratio - the larger the dam, the longer the walls - speak with your contractor
  • We are liner experts so make sure you seek advice from a civil contractor first - they are the earthworks & design experts
