When does the expansion of a brick wall occur?
Brick walls move both horizontally and vertically due to changes in temperature and moisture content. When a brick wall is heated it gets larger and when it cools it gets smaller. When brick gets wet, it expands. Approximately 85% of its maximum expansion occurs in the first 18 months after firing. Sixty percent expansion
