In the Front Range, expansive clay is a significant driver of foundation issues because it causes both heaving and settlement through a continuous shrink-swell cycle.
According to the provided content, the region’s clay-rich soils undergo dramatic volume changes based on moisture levels:
- Heaving (Upward Movement): This occurs when the expansive clay absorbs moisture from heavy rains or snowmelt, causing the soil to swell and push the foundation upward.
- Settlement (Downward Movement): This occurs as the clay contracts and shrinks during dry spells, causing the structure to move downward.
Because of these seasonal cycles, both movements frequently affect the same foundation over time. This makes the Front Range particularly challenging for structural stability, as the soil can move in opposing directions depending on the weather. Due to this complexity, the content emphasizes that a structural engineer should perform a site-specific soil analysis and elevation survey to distinguish between the two movements before selecting a repair solution.
