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:
“Rub a half potato on your wart
and wrap it in a damp cloth. Close
your eyes and whirl three times and throw.
Then bury rag and spud exactly where they fall.”
—Richard Hugo (1923–1982)
“If any doubt has arisen as to me, my country [Virginia] will have my political creed in the form of a “Declaration &c.” which I was lately directed to draw. This will give decisive proof that my own sentiment concurred with the vote they instructed us to give.”
—Thomas Jefferson (1743–1826)
“The inconveniences and horrors of the pox are perfectly well known to every one; but still the disease flourishes and spreads. Several million people were killed in a recent war and half the world ruined; but we all busily go on in courses that make another event of the same sort inevitable. Experientia docet? Experientia doesn’t.”
—Aldous Huxley (1894–1963)
