Why are foundation issues common in Houston’s clay soil?

Foundation issues are common in Houston largely because of its clay-rich soil, which is highly reactive to moisture changes. This type of soil is known as expansive clay—and it’s one of the leading causes of foundation movement in the region. 🏠🌍

1. Swells When Wet 💧
   During heavy rains or plumbing leaks, clay soil absorbs water and expands, pushing upward against the foundation. This causes heaving, cracks, and uneven floors.
2. Shrinks When Dry ☀️
   In hot, dry weather, the same clay soil shrinks and contracts, pulling away from the foundation and leaving voids. This leads to settling and sinking.
3. Uneven Moisture Distribution
   Houston often experiences cycles of drought followed by storms. These rapid moisture changes lead to inconsistent pressure under the home, which stresses the structure.
4. Poor Drainage in Flat Terrain
   Houston’s low-lying, flat land makes it harder for water to drain properly. This results in water pooling around the foundation, worsening soil movement.

Because of these natural soil behaviors, foundation repair is a common necessity in Houston. Regular maintenance, proper drainage, and early inspections are key to preventing costly damage. 🛠️✅
