Foundation Conditions in Houston
Houston sits on Gulf Coast alluvial clay and is subject to both soil expansion and significant land subsidence - the ground itself has sunk measurably in parts of Harris County over the past century due to groundwater extraction.
Houston's subtropical climate means high humidity year-round with frequent heavy rainfall. Poor drainage around foundations is the leading preventable cause of foundation damage in the Houston metro.
Common Foundation Types in Houston
Houston homes commonly use slab-on-grade construction. Many older Bayou City homes also have pier-and-beam foundations, which can be more forgiving in wet conditions but require maintenance to prevent rot and pest damage.
Most Common Foundation Problems in Houston
- Slab movement from clay expansion
- Pier-and-beam rot and settling
- Flooding-related foundation undermining
- Subsidence cracks
- Drainage-driven erosion
