Frost heave occurs when soil expands and lifts due to freezing and thawing cycles, potentially damaging plant roots, foundations, or hardscape elements. When water in the soil freezes, it expands, causing the soil to rise and displace anything above it. Frost heave is a concern in colder climates, particularly for shallow-rooted plants or structures built on poorly drained soils. Proper drainage and insulation can help prevent frost heave.
