Is it possible to determine the rate of movement of a foundation crack at the time of inspection?

The ability to determine the rate of movement of a foundation crack during an inspection can be quite challenging. Typically, a single inspection does not provide the necessary time interval needed to assess how quickly a crack is moving. Even if there are signs of recent activity, such as fresh breaks or displaced material along the crack, this alone does not reveal a precise rate of movement.

This type of assessment usually requires repeated measurements over a period of time to identify patterns and rates of movement accurately. Without the ability to compare measurements taken at different times, it is not feasible to comment on the rate. In most inspection scenarios, professionals focus on the current state of the cracks. Therefore, concluding that it cannot be determined aligns with the reality of the situation and the nature of inspections.
