Types of foundation movement: this article discusses how to evaluate and diagnose foundation cracks and movement classified by the type of movement that is occurring: horizontal movement, vertical movement, bulging or bowing walls, leaning or tipping foundation walls, and other forms of foundation settlement or heaving. This chapter of the "Foundation Crack Bible" discusses in detail the recognition of different types and causes of building foundation movement and foundation damage. We distinguish among vertical movement, horizontal movement, leaning, tipping, bending, differential and uniform settlement, earthquake and storm damage, and other foundation damage patterns.

Vertical movement in foundations, in the most general cases, is caused by downwards movement of the wall or wall footings such as when a wall footing sinks in soft soil, or by an up and down movement of the wall or wall footings such as when a wall is disturbed by frost in a freezing climate or by expansive clay soils which expand or shrink as their water content increases or decreases.
Horizontal movement in building foundations or walls is generally caused by an external lateral or "sideways" force applied to some portion of the wall. Depending on the construction materials used and the strength of a foundation wall, a force applied to the wall can cause it to move in any of several ways which we discuss in detail at HORIZONTAL MOVEMENT IN FOUNDATIONS.
We discuss the inspection and analysis of foundation damage which shows a combination of different movement directions, forces, or crack patterns in detail at COMBINATIONS OF FOUNDATION MOVEMENT including the following examples of combination foundation damage:
