Texas is known for its diverse landscapes, from dry deserts to humid coastal regions. However, one thing that most Texas homeowners deal with is soil movement, a major factor affecting the longevity of foundations. The state’s soil composition can cause foundation issues, leading to cracks, shifts, and structural instability over time. DuraTech Texas would like to share why understanding how local soil types impact your home’s foundation can help you take proactive steps to protect it.
Common Soil Types in Texas & Their Impact on Foundations
The type of soil your home is built on determines how well your foundation will hold up over time. Let’s break down the major soil types found in Texas and how they affect your foundation.
Expansive Clay: Expansive clay soil is one of the biggest threats to foundations in Texas. Found in areas like Houston, Dallas, Fort Worth, and Austin, this soil swells when wet and shrinks when dry. These drastic changes put stress on foundations, causing them to shift, crack, or even sink over time. Signs of foundation issues in clay soil are:
• Large cracks in walls and floors
• Doors and windows sticking or misaligning
• Uneven or sloping floors
Sandy Soil: Sandy soils, found in El Paso, parts of West Texas, and the Gulf Coast, drain water quickly and don’t expand as much as clay. However, they lack stability and can shift over time, leading to foundation settlement. Signs of foundation problems in sandy soil:
• Sinking or settling foundation
• Gaps between walls and flooring
• Cracks in exterior bricks
Loamy Soil: Loamy soil is a mix of clay, sand, and silt, making it one of the best types for foundations. It retains some moisture without excessive expansion or contraction. However, in regions like San Antonio, Austin, and the Hill Country, loamy soil can still erode if not properly managed. Signs of foundation issues in loamy soil may be:
• Minor settling or small foundation cracks
• Water pooling near the foundation
• Soil erosion near the home’s perimeter
Silt and Silty Clay Soil: Silt-based soils are found in East Texas and tend to retain a lot of water, making them prone to shifting and settling. They can behave similarly to clay when wet, causing foundations to become unstable. Signs of foundation problems in silty soil include:
• Water pooling around the home
• Soil becoming soft and shifting underfoot
• Cracks forming in the foundation after heavy rain
How to Protect Your Texas Foundation from Soil Movement
Since soil-related foundation problems are common in Texas, homeowners should take preventive measures to avoid costly repairs. Here are some key steps to protect your home’s foundation:
• Maintain Consistent Moisture Levels: In dry months, use soaker hoses around the foundation to prevent soil shrinkage. Avoid overwatering, as excessive moisture can lead to soil expansion.
• Improve Drainage Around Your Home: Install gutters and downspouts to direct rainwater away from the foundation. Ensure proper grading so water flows away from the home instead of pooling.
• Use Foundation Piers in High-Risk Areas: Homes built on expansive clay or loose sandy soil benefit from deep piers to provide stability. Helical piers or concrete pilings can help anchor foundations to stable ground.
• Regularly Inspect for Foundation Damage: Look for cracks, uneven floors, and door alignment issues every few months. Schedule a professional foundation inspection every few years, especially if you notice early warning signs.
