AbstractThe mechanisms responsible for the wetting of masonry are reviewed; in addition to rain falling on walls, these include: condensation of water vapour diffusing through the masonry materials and of that contained in the air passing through masonry pores or wall openings, "wicking" of ground moisture into masonry, and flooding of water onto masonry because of defective drains and flashings. The effects of the wetting of masonry on certain aspects of its performance, and the design and construction features of masonry walls that influence their wetting, are also discussed.
