I have been looking for an alternative solution for a dunking pool.
I have been researching oversized cast planters. They can be very large.
I have been looking at this one:
REALLY BIG PLANTER
This is cast, with 3/8" rebar reinforcement. Also a hole on the bottom
My question is..... If i wanted to make the inside waterproof, what steps would I need to follow. Obviously there would be a plastering step, but do i need to do some sort of waterproof coating over the the bare interior?
Thanks....
Paul
