 However he has recently clarified this statement on a comment post made on the Surveying Property website,

Konrad Fisher's article "The Fraud of Rising Damp" points out that the historic city hall in Bamberg stands in the river Regnitz and its bridge remains dry without any chemical, mechanical or electronic damp-proof course.However, proponents of rising damp suggest that not all walls are capable of supporting rising damp, so merely observing that rising damp does not occur in a particular wall does not disprove its existence in other walls.In 1997 the housing disrepair team at Lewisham Council in south London were so convinced that rising damp was a myth that they offered a reward of £50 to anyone who could show them a genuine case of it.
