I can vaguely remember seeing a prog on tv a good few years back which
showed a cellar under a college or university where they had pillars of
various bricks ie breeze block,red brick,stone cladding etc stood in baths
of water which was topped up daily, over a number of years they had
concluded that damp cannot rise up the pillars. If anyone knows where this
is/was then it should make interesting info.
