• Moisture problems in exterior masonry walls can be caused by either water leakage or air infiltration-condensation, or a combination of both. However, because many symptoms of water leakage and air infiltration-condensation are similar, it's vital to investigate both, even when the problem seems to clearly indicate one or the other. A pronounced symptom of one may be overshadowing a symptom of another. For a balanced investigation of an exterior masonry wall system's moisture problem, you should: Review the wall construction and the mechanical system
  • Survey the interior conditions
  • Conduct water leakage tests
  • Measure actual pressures within rooms
  • Do infrared analysis to determine the mechanism of moisture migration within a wall system
  • Analyze and test a mock-up
