HDPE Liners


There are a variety of geomembranes available to line dairy effluent ponds, each with varying life expectancy, cost and performance. 

For the team at Enviroline NZ the choice was easy – High Density Polyethylene (HDPE) as the superior performance and numerous benefits far outweigh other geomembranes.

Internationally and within New Zealand HDPE is the most widely used geomembrane; used for lining: Landfills, waste water treatment ponds, (including dairy factory and meat works waste treatment ponds), dairy effluent ponds, irrigation dams, canals and hazardous waste containment.

High Density Polyethylene (HDPE) Properties:

  • Extensively used within New Zealand for over 30 years
  • Supported with manufacturers 20 year warranty
  • Extremely cost effective
  • Maintenance free
  • HDPE has high chemical resistance, including resistance to dairy fats and oils, and common dairy shed sanitising chemicals
  • Evaluated and approved for use with farm dairy effluent by the manufacturer
  • Unique welding process with  double seams, provides greater containment security
  • Reliable fully tested welds
  • Independent papers predict the life expectancy of exposed HDPE liner is in excess of 36 years
  • Continuous testing during product manufacturing ensures quality assurance
  • The product can be traced back to a single polymer during manufacturing
  • Each roll is batch tested during manufacturing , with batch number recorded
  • Manufactured to international GRI-GM13 standards
  • Meets the requirements set out in IPENZ Practice Note 21

Ultimately HDPE liners provide the most secure containment possible.
