AbstractEnjoying the low maintenance of masonry along with its long-term durability requires that particular attention be paid to those building details that help prevent or divert concentrated flows of water from exterior masonry walls. The careful installation of flashing, overhanging copings or caps, drips, eavestroughs and downspouts, among several other details, can prevent staining, efflorescence, and biological growth on the masonry. Mere unsightliness, one could say. But drenched masonry, given a few freeze-thaw cycles, soon begins to spall, and worse, leads to corrosion of ties. Adieu, long-term durability!
