BRE GR33/1 PDF

Moisture can enter buildings for many reasons and the resultant damage to materials and components is well documented. There is much published guidance on the identification and possible remedies for moisture defects. 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. The number of techniques is large so only a limited number can be reviewed. Part 1 summarises the sources of moisture in building fabric and gives advice on analysing the possible causes.
