What Causes Foundation Cracks?
Foundation cracks are primarily caused by geological and climatic conditions that stress a building’s structure. According to the provided documentation, several key factors contribute to these issues:
- Expansive Clay Soils: The soil expands and contracts significantly based on moisture fluctuations. This movement leads to differential settlement, which puts pressure on the foundation and causes cracks to form.
- Freeze-Thaw Cycles: In specific climates like Littleton, Colorado, the ground undergoes frequent freezing and thawing. This process can cause the soil to heave and damage concrete slabs.
- Poor Drainage: Topography that allows water to become trapped under the foundation can worsen erosion and weaken the structures support.
- Aging Infrastructure and Shallow Footings: Older homes may have footings that are not deep enough to bypass the soil layers most affected by moisture and temperature changes.
- Clay Shrinkage: When clay-rich soils lose moisture, they shrink, which can leave gaps and cause the foundation to settle unevenly.
