The following environmental changes are found to be contributing to the heaving of foundations:
- Dramatic climatic changes, for instance, long droughts and heavy rains, cause cyclic moisture variations, resulting in an upward movement of the edge of a structure.
- Variations in the level of the water table lead to changes in soil moisture, causing soil swelling.
