I have very sandy soil in Western Australia and would like to build a
pond system but use natural methods to seal it, if possible. Does
anyone have any info or references on this topic?

Thanks

Hi,
I just recently read an article that is posted on
http://permakultur.net/texte/teich/index.html about this. It gives
some suggestion and one place and name that should help you to follow
up on it. See in the paragraph under "Vergleiung". This article is in
German.

Hope this helps
Richard
