Cloud 9 is, in fact, a reference by the International Cloud Atlas, first published in 1896. Its initial purpose included aiding the training of meteorologists and promoting more consistent use of a vocabulary describing clouds—cloud 9 being one of the highest. Many are familiar with the term as an expression of bliss, and maybe that is how design professionals and craftsmen feel when a concrete design comes full circle. The article that started The Concrete 9 series, published in 2011 in The Construction Specifier magazine, was the foundation for developing products that are now common in the marketplace.
