A building inspector will determine whether an engineerâs report is necessary as some cracks in the walls may not signal major structural issues, for example, vertical cracks.

Hairline Cracks in Concrete Slab Hairline cracks in a concrete slab are rarely a cause for concern.They can be controlled, but not eliminated.

The words and terms defined in ACI 318 shall, for the purposes of this chapter and as used elsewhere in this code for concrete construction, have the meanings shown in ACI 318 as modified by Section 1905.1.1. A crack in a slab of 1/8 inch or less is typically a normal shrinkage crack and not a cause for concern.

There is no one definitive cause for cracks but the minor changes in the temperature and moisture within building materials can be enough to cause hairline fractures in the surface.
