Hi All,
I am studying Sustainable Building and Renewable Energy and have to complete a project on a building defect for my Building Pathology module.
I have chosen my own garage wall as the defect.The crack in question is almost perfectly vertical which has led me to question whether it is subsidence or not. The crack does not extend to the base of the wall and is far wider at the top than it is at the bottom.
Im really stumped by thisand would appreciate some advice from anybody more knowledgeable than i am.

Unfortunately i cannot provide pictures as i have just joined this forum and am not permitted to yet. Ill gladly send pictures to anyone willing to help.

Thanks in advance,
Gavin.
