Higher buildings and pre-fabricated walls have resulted in an increase in the rate of occurrence of rain penetration. The forces that cause this water infiltration through modern walls are wind induced and can only be altered at the design stage. This paper describes an experimental and computational study of the processes of water ingress and proposes design features to minimize or eliminate them.
