How Does Drought Affect a Home's Foundation and Soil?

Drought removes moisture from the ground, and as the soil dries, it shrinks and contracts. This is especially true for clay-rich soils, which are common in many areas. The shrinking creates voids or empty spaces beneath and around your foundation.

When the soil pulls away, your foundation loses the support it normally has. This can cause the foundation to settle unevenly, leading to cracks in the concrete, brick, or block. You might notice doors or windows that stick, or gaps between the foundation and the ground.

You can reduce drought-related damage by keeping the soil around your foundation consistently moist. Use a soaker hose or drip irrigation to water the soil near the foundation, especially during dry spells. Avoid overwatering, which can cause its own problems like soil erosion or hydrostatic pressure.

Also, maintain proper drainage around your home. Ensure gutters and downspouts direct water away from the foundation. Planting trees or large shrubs too close to the house can also pull moisture from the soil, so keep them at a distance. If you notice new cracks or shifting, it's wise to have a professional inspect the situation.

Drought can lead to water damage in an unexpected way. When the soil shrinks and pulls away from your foundation, it can create pathways for water to flow toward your home. Heavy rain after a drought can then cause water to pool around the foundation or seep into basements or crawl spaces.

If you experience water intrusion after a dry period, you may need to address both the foundation issue and the water damage. Local water damage pros can help with cleanup and drying. They can also work with you to prevent future problems, such as improving drainage or sealing cracks.
