Abstract
The water permeabilities of about 100 small masonry-wall specimens were measured before and after exposing them to the weather at Washington, D. C., for a maximum period of 3 years. Some of the more permeable walls had been waterproofed before exposure, and the durability of the waterproofing treatments, as well as the structural appearance or condition of the walls, was also determined. The exposure did not have an important effect on the permeability of all-brick or brick-faced walls 8 in. or more in thickness. The permeability of stucco-faced walls was slightly increased. Repointing of the face joints was the most effective and durable of the waterproofing treatments.
