OI implements methods for determining and evaluating causes of water leakage through the building envelope. Water penetration (leakage or intrusion) can be problemmatic if moisture levels exceed the planned resistance or temporary retention and drainage capacity of the wall, is causing or is likely to cause premature deterioration of a building or its contents, or is adversely affecting the performance of other components. Investigative techniques may be intrusive, disruptive or destructive.
