Any masonry structure unprotected by a properly installed
Damp Proof Course is prey to rising damp.
Moisture will rise by capillary action (a suction
phenomenon arising at the boundary between moisture and a
small tube, crack or other tiny, enclosed passageway)
through the pores of the masonry, seeking a means of
evaporation.
The moisture will continue to rise until it reaches a
height, where unless no evaporation is possible, gravity
takes over and pulls it down again.
This height is seldom more than 1.20m.
However, it is often misdiagnosed by unscrupulous or
inexperienced builders.
Make
sure the problem is not for example - leaking guttering,
faulty or leaking plumbing or condensation caused by
inadequate ventilation.
