How Freeze-Thaw Cycles Move Soil and Structures
Frost heave is upward soil movement caused by freezing conditions and ice lens formation in moisture-bearing soils. When thaw occurs, soils can settle unevenly, leaving support variability that contributes to cracking and slab distress.
How Frost Heave Develops
- Soil moisture is present in the freezing zone.
- Cold temperatures drive ice formation and volume increase.
- Ground lifts and loads are redistributed.
- Thaw can leave voids or softened support zones.
Where Homeowners Notice It
- Seasonal slab cracking and movement near exterior edges.
- Walkway and hardscape displacement after winter.
- Short-term sticking doors or interior alignment changes.
- Recurring wet-zone performance issues in spring thaw periods.
Reducing Frost-Related Risk
- Keep drainage away from structural edges to reduce freeze-zone moisture.
- Stabilize runoff pathways and eliminate chronic saturation pockets.
- Assess existing movement with foundation inspection.
