Guide to Wall Cracks

Step Crack

Often found on masonry walls, they appear like steps in the brickwork/blocks and typically follow mortar lines. The mortar and masonry deteriorates due to the movement of the affected wall.

Horizontal Crack

Found running horizontally between bricks and in some instances, they transition to become a step crack. Internally they typically appear as gaps between the skirting board and floor or between the cornice and ceiling.

Articulation Joint Crack (Expansion joint)

Usually visible in building extensions where two walls join and in modern buildings at the sides of large window and door openings. The gap is often wider at the top of the joint, exposing the lining.

Corner Crack

Buildings built using clay bricks are susceptible to cracks in corners as overtime the clay expands creating lateral force pushing against each other. The mortar around the clay brick deteriorates exposing gaps in the brickwork.


Evident in both masonry or concrete walls where the crack is wider at the top, indicating the wall settling or heaving. They are normally jagged or zig-zag and don’t follow a uniform pattern.
