It is mostly formed by uneven settlement of foundation.

Horizontal crack

Horizontal crack refers to the cracks formed in the wall of a building along the horizontal direction. Horizontal cracks are mostly caused by temperature stress damage. In exterior walls, it is common at the junction of different materials. Such as: the joint of concrete beam or concrete floor (house) cover and brick wall. Its shape is a horizontal straight line. It is in a "one" shape.
