Overloading is another cause of foundation failure. Changes in the use or structure of a building result in an increase in loads that were not accounted for in the original design, leading to concentrated stresses in specific parts of the foundation. Similarly, shallow foundations on clay soils are susceptible to seasonal shrinkage and expansion, which creates a cycle of uneven settlement, leading to wall slumping and the formation of cracks around openings. Diagnosing foundation failure involves the use of internally and externally placed signaling devices to monitor movement, supplemented by photographs to accurately document the extent and direction of cracks. This diagnostic process is critical in determining whether movement is occurring and deciding on appropriate remedial measures, and often requires the expertise of a foundation engineering specialist. In summary, understanding the causes and symptoms of foundation damage is critical to maintaining structural integrity. Through diligent diagnosis and intervention, the risks associated with foundation problems can be mitigated to ensure the longevity and safety of the building structure
