Houston, Texas, with its unique geographical and environmental characteristics, faces specific challenges when it comes to concrete slab foundation issues. The causes of foundation problems in Houston are influenced by the region’s soil composition, weather patterns, and urban development. Today, we at DuraTech Texas would like to share the factors that contribute to concrete slab foundation issues in the Houston area.
When Should I Be Worried About a Slab Foundation?
Expansive Clay Soils: Houston is known for its expansive clay soils, particularly the highly expansive clay of the Eagle Ford Formation. This type of soil has a high clay content, making it prone to significant volume changes with variations in moisture levels. During periods of heavy rainfall, the soil expands, and during droughts, it contracts. This cyclical movement can exert pressure on foundations, leading to cracks and shifts.
High Humidity & Moisture Levels: Houston’s subtropical climate brings high humidity and frequent rainfall, creating an environment conducive to soil moisture fluctuations. The constant expansion and contraction of the soil can impact the stability of concrete slab foundations, making them more susceptible to damage over time.
Poor Drainage: Houston experiences intense and sporadic rainfall, and poor drainage exacerbates foundation issues. Improperly directed runoff water can accumulate around foundations, leading to soil erosion and instability. Addressing drainage issues is crucial for preventing water-related foundation problems.
Gulf Coast Hurricanes: The Gulf Coast, including Houston, is prone to hurricanes and tropical storms. Severe weather events can bring heavy rainfall, storm surges, and strong winds, all of which can contribute to foundation issues. The excess water from storms can saturate the soil, leading to instability and potential foundation movement.
Subsidence: Parts of Houston are affected by subsidence, which is the gradual sinking or settling of the ground. Groundwater extraction for urban development and industry can contribute to subsidence. As the ground subsides, it can affect the foundation, causing uneven settling and potential structural damage.
Urban Development and Impervious Surfaces: Houston’s rapid urbanization has led to an increase in impervious surfaces such as roads and buildings. These surfaces prevent water from being absorbed into the ground, leading to concentrated runoff. This altered hydrology can impact the moisture content of the soil around foundations, contributing to foundation issues.
Tree Roots: Houston’s lush greenery includes large trees with expansive root systems. When these trees are located in close proximity to homes, their roots can seek moisture beneath the foundation. As the roots grow, they exert pressure on the foundation, potentially causing damage over time.
Clayey Loam Soils: Certain areas of Houston have clayey loam soils, which, while not as expansive as clay, still undergo changes in volume with moisture variations. Homes built on clayey loam soils are also at risk of foundation issues due to soil movement.
