Drought causes clay-rich soils to lose moisture and contract, leading to uneven ground shrinkage that can damage house foundations and cause cracks. When rain returns, soils may swell unevenly or collapse suddenly due to weakened soil structures and displaced particles, exacerbated by factors like leaking drains or soakaways. Soil behavior varies locally, influenced by foundation depth, vegetation, and drainage conditions. Soil degradation from drought also impacts erosion, microbial activity, and crop yields. Homeowners should monitor cracks and structural changes, ensuring proper drainage and consulting professionals if damage progresses.
