It has been suggested that I could use ICF blocks for the pond (foam building blocks with cement added) to build my pond. Then add a box liner. Has anyone used ICF blocks in their pond build?

Do a search on Koiphen and you'll find several. Koi Acres did a very nice ICF build few years back. Look to see if it's still on their site.

I havent used ICF but I have used permanent PVC formwork which is fully waterproof. If your going high walls, you only need to brace support one side. I was able to concrete pour the walls and floor at the same time (monolithic) which reduces leaks as there aren't any cold seams.

In Australia, polystyrene is prone to termites due to soil moisture.
