Abstract

Literature on permeance of brick and concrete masonry walls to wind-driven rain is reviewed. The force and quantity of rain on walls is discussed. The mode of water entry into the face of masonry through various kinds of cracks is reviewed. Wall design in several aspects is considered. Workmanshi and materials selection are discussed. Flashing, sealants, and metals in walls are reviewed. Repair procedures are outlined. Recommendations are made for materials, design, construction, and maintenance of masonry to reduce water permeance of walls above grade. More than 60 references are cited and a bibliography lists 233 entries under nine key words.
