• Crack record cards to record changes in crack width

Fixing:

• Either Stainless Steel Discs or marks may be used with the Digital Calipers.
• Fix the Discs or marks with the Plastic Padding about 80—100mmm either side of the crack to be monitored.
• The line of the Discs or the marks should be perpendicular to the crack.
• Allow the Plastic Padding to harden thoroughly before taking the first reading.

  Monitoring:

• The distance between the Discs or the Avon marks is measured and recorded on the record card.
• The rates and trends of movement becomes apparent as subsequent readings are taken.
• Monitoring to +/- 0.1mm is sufficiently accurate for most building structures.

• Cracks may be monitored in corners using corner discs either fixed with screws and rawlplugs or plastic padding.
• Corner discs are either used singly to monitor two-dimensional movement or in pairs (as shown) to monitor movement in three dimensions.
