I've tried a lot of different materials in pond making from pounding clay, to rubber liners, old oak barrels and preformed fiberglass to cement.
I wish I was am to have a natural pond, but alas...
While I like cement ponds, I tend not to recommend them to others since most people's enthusiasm wanes quickly and there is nothing that saddens me like seeing a cement pond sitting empty.
Rubberliners leak too easily.
Currently, I make do with old bath tubs.
If given your choice, what is your favorite material to use for a man made pond?
