Cracks in Buildings

Interpreting whether a crack is of structural significance is usually seen as one of the more challenging aspects of a Surveyor’s role when establishing the condition of a building. There can be a tendency to err on the side caution and conclude that cracks which have appeared in a wall are naturally symptomatic of ground subsidence. Subsidence is, however, comparatively rare and the number of cases where further action is required is minimal. The Surveyor should therefore first try discount less serious causes. To do this requires only a relatively basic understanding of the principles of physics and building construction. Bricks and...
