I am planning to build an above ground fish pond. The structure will be make out of wood. I plan to sheet the outside of the structure is some kind of suitable board and then tile it with something like these: Faux thin Brick | Greenway Systems

My question is what will a suitable material/board be to fasten to the wooden structure that I can tile over. The board and tiles will not be in direct contact with the pond water, but it will be outside exposed to the elements, rain, sun etc.

Thanks in advance.
