Top Causes of Foundation Problems in San Antonio

Understanding the Leading Causes of Foundation Problems in San Antonio, Texas
San Antonio, Texas, frequently faces challenges with foundation issues in homes and buildings, a predicament largely resulting from the specific soil characteristics prevalent in the region. The root of foundation complications lies in the state’s unique soil composition and the resulting environmental dynamics, causing Texas to top the list for foundation troubles across the U.S.

The ground upon which foundations are constructed in Texas consists of expansive clay soil and rich, black dirt, two soil types well-known for causing structural instability. While black dirt is incredibly fruitful for agriculture, it poses a significant challenge when laying the groundwork for a building. The expansive clay soil swells when it comes into contact with water, leading to shifts beneath structures. Such shifts result in common foundation issues such as water damage, door and window malfunctions, tilting chimneys, and wall or brick cracks. Clay soil is common in Northeast San Antonio in the suburbs of Converse Texas, Selma, Cibolo, Schertz, Kirby, Universal City Texas and into the West Southwest areas of San Antonio such as the Lackland AFB area and Castroville Texas area.
Seasonal variations cause these soils to fluctuate between dry and moist states, further promoting soil movement and affecting the stability of foundations.
