Is now a good time for you to perform preventative soil maintenance on your home's foundation?
Persistent drought conditions across Oklahoma have caused soil to shrink, leading to increased reports of home foundation settling. This shift has resulted in structural concerns for many residents as soil loses the moisture needed to support home foundations.
Why it matters
The high clay content in Oklahoma soil causes it to shrink significantly when dry, which can lead to costly cracks in brick veneer and interior walls. Drought conditions have intensified these natural soil movements, prompting a surge in requests for professional inspections.
Engineers report that 80 percent of inspection calls are now linked to drought impacts. This follows a trend observed over the past 20 years, during which local soil moisture levels have dictated the stability of residential foundations.

The details
Oklahoma soil is characterized by a high plastic index, meaning it expands and contracts rapidly based on moisture levels. When drought removes this moisture, the soil shrinks, causing foundations to lose their support, which leads to settling or rotation. To mitigate this, homeowners can maintain consistent moisture levels by watering the soil near their foundation for 10 to 15 minutes, or by working wet soil into any visible separations to ensure proper slope away from the home.

The Home Front
The regional prevalence of clay soil with a high plastic index makes Oklahoma foundations uniquely susceptible to moisture-driven movement. This cycle of expansion and contraction remains a primary driver of long-term property maintenance costs and structural concerns for state homeowners.
Walk around your home to check for new cracks in brick veneer or interior drywall, which may indicate foundation settling. If you identify significant separations, contact a licensed structural engineer to assess whether professional intervention is required for your property.
The takeaway
Maintaining consistent soil moisture is a practical defense against foundation movement during dry periods. Consider establishing a routine to water the soil perimeter of your home for 10 to 15 minutes to help mitigate the effects of extreme drought on your foundation.
