The causes of problems

Types of movement

Types of movement

Raking Crack

A crack that runs diagonally across a wall. Typically it will follow the mortar joints but it can also cross bricks. Damage to bricks is very much dependent on the strength of the mortar.

Vertical Crack

A crack that runs vertically (or close to this) up a wall. The direction must be vertical but it may follow mortar joints. This type of cracking can be caused by insufficient movement joints, particularly in block walls.

Settlement Crack

This generally refers to the cracking that frequently occurs in the first year or so after a structure is finished.


Although similar problems tend to result in similar crack patterns, expert advice should always be sought. Every property is different and should be treated as such.
