Abstract Outline: This paper will draw on the authors experience of various irrigation works in Australia and New Zealand to look at the various options that are available and to help with selection of appropriate options for different circumstances.

In particular it will challenge the view that HDPE is synonymous with geomembrane and that indeed there are now variations in the world of HDPE.  It will discuss various HDPE alternatives such as PVC, Elvalloys, EPDM and coated fabric geomembranes.  It will provide a comparative matrix of different geomembranes and their respective properties.

Finally it will discuss the combined effects of geomembrane choice and associated subgrade preparation requirements and point to some circumstances where a more expensive geomembrane choice might lead to a solution that is less expensive overall.
