How well sealed were the raised floors?
Not at
all. They were 2 foot squares sitting on adjustable
pillars. Each pillar supported 4 tiles where they all met
at the corners. You could easily slip a punch card (or
credit card) between most of the tiles. Anything poured on
the floor would run down between the tiles.
