  • Masonry & Wall Moisture Intrusion Investigation & Testing

    Testing water leaks in walls made of masonry as well as other materials requires an understanding of how the leaking wall was constructed. Is there a secondary layer of masonry? Is there a house wrap or vapor barrier? Are there flashings at key areas and how well were they installed? Are control joints and caulk joints intact and working?

    Our on-site investigation includes…

    • Review available window shop drawings and architectural drawings
    • Inspection and survey building facade and roof
    • Inspection and survey interior leak locations
    • Use infrared camera and moisture meter to discover leak locations
    • Propose further investigations which might include:
    • Invasive testing with moisture meter
    • Invasive testing with endoscopic video camera
    • Destructive testing to observe water management layer
    • Spray rack testing
    • Prescibe remedial measures
    • Follow-up testing to validate effectiveness of remedial measures

After the first set of readings, the plastic tare sheet is removed. Then the readings are taken again. The difference between the initial and current air flow readings are attributed to the skylight. If the airflow measured through the skylight is less than what is allowed, then the test is a PASS.
