The objective of this Good Repair Guide is to provide building professionals with examples of analytical techniques which could be used to supplement visual information in the identification of moisture problems. Part 3 gives advice on how to interpret the data gathered from moisture meters or drilling samples from walls recording environmental data logged by sensors over a period of time can establish patterns, such as a rise in humidity linked to a rise or fall in temperature. This gives clues to the cause of the moisture problem. 6 pages.
Good Repair Guide 5 ’Diagnosing the causes of dampness’ covers the subject more briefly.
