Foundation corner cracks are extremely common in residential concrete foundation slabs. These cracks are also commonly referred to as slab cracks. They occur, as the name suggests, at the corner of the foundation where brick veneer is installed on the house. That’s right, they only occur along walls that have brick veneer on the outside of the house.
Characteristics of a foundation crack include a “wedge” shaped crack in the concrete often including a slight displacement or shift in the concrete wedge. The crack usually starts 3 to 8 inches from the corner of the concrete and is located on both sides or faces of the foundation.
