Evaluating moisture levels within building envelopes requires the application of both destructive and non-destructive test methods.  Non-destructive test methods such as infra-red, capacitance meter or nuclear meter are utilized to cost effectively and efficiently examine selected sub-assemblies of existing building envelopes for latent moisture.  Destructive testing is required to establish test parameters and calibration of the various non-destructive test methods and to verify anomolies identified during non-destructive testing.

• Testing:  Sub-assemblies of the building envelope are evaluated utilizing state-of-the-art non-destructive equipment, providing a cost effective, efficient means of locating anomolies indicating the possibility of moisture presence.
• 
  Identification: Anomalies are sometimes marked on the surface being evaluated during the survey, in addition to being identified on the scaled drawing.
  
  
• Verification:  The presence of moisture is physically confirmed by means of destructive testing of materials within anomalies identified during the survey.
  
  
• Location:  Verified anomalies are recorded on a scaled drawing.
  
  
• Documentation:  Photographic and/or video tape documentation of anomalies is provided.
  
  
• Written Report:   A compilation of the results of the moisture survey is provided for use as a reference tool for future asset management decisions.
