Yes, a foundation can experience both settlement and heaving simultaneously or sequentially over time. This dual movement is particularly common in regions with expansive clay soils or significant seasonal moisture variations.
According to the provided technical guide, this combined movement can occur in several scenarios:
- Differential movement: One area of a foundation may experience soil consolidation (sinking), while an adjacent area with expansive clays absorbs moisture and swells (lifting).
- Variable site conditions: Interior columns might settle due to poorly compacted backfill, while the perimeter of a shallow foundation experiences frost heave.
- Plumbing issues: A leak can soften the soil in one section, leading to settlement, while the migrating moisture triggers heaving at the slab edges.
Because these conditions create opposing stress fields, they often result in severe structural damage, such as diagonal cracking and warped door frames. It is critical to have a structural engineer perform a thorough evaluation, including soil analysis and elevation surveys, to isolate the root causes and design a repair strategy tailored to both active mechanisms.
