Damp Proof Courses
Moisture may ascend into a building from the foundation of a wall or gain ingress into a building from a wet patch of ground, where it meets a solid wall. The manifest result of this process is called damp. One of many methods of resisting such ingresses of water is to construct the wall with several low courses of dense engineering bricks such as Staffordshire blue bricks. This method of damp proofing appears as a distinctive navy blue band running around the circumference of a building. The efficacy of this means of keeping out damp is more limited by the permeability of the mortar bedding and perpends joining the bricks, than by that of the bricks themselves.

Famous quotes containing the words damp, proof and/or courses:
“Men felt a chill in their hearts; a damp in their minds. In a desperate effort to snuggle their feelings into some sort of warmth, one subterfuge was tried after another ... sentences swelled, adjectives multiplied, lyrics became epics.”
—Virginia Woolf (1882–1941)
“O, popular applause! what heart of man
Is proof against thy sweet, seducing charms?”
—William Cowper (1731–1800)
“However, our fates at least are social. Our courses do not diverge; but as the web of destiny is woven it is fulled, and we are cast more and more into the centre. Men naturally, though feebly, seek this alliance, and their actions faintly foretell it.”
—Henry David Thoreau (1817–1862)
