Abstract:

In order to diagnose and treat moisture-related problems in historic buildings, it is necessary to measure moisture levels in walls. This review describes equipment and procedures for measuring moisture in building materials. As well as those commonly employed, it includes techniques which can only be used in the laboratory as they are impractical in the field, and equipment which is being developed and tested but not yet in widespread use. Some approaches are simple and standard practice; others require specialist expertise and equipment, or long term on-site installations. The techniques are evaluated based on their practical application for use in situ, for monitoring moisture changes both at the surface and through the profile of a wall.
