San Antonio Soil Conditions
San Antonio area soils are composed of stratified loam, clay, and sand. They are mostly fine, but there are scattered rocky areas throughout the area. In places, the bedrock in San Antonio is quite shallow. Most of the soil in San Antonio is moderately expansive, meaning that it swells and shrinks depending on the moisture content, but not in a way that would threaten a home’s foundation. Overall, when compared to other cities in Texas, San Antonio’s soil is relatively stable.
If you would like to take a detailed look at the soil in your neighbourhood, consider looking at the United States Department of Agriculture’s Soil Survey Tool. It can give you an in-depth look at exactly what type of soil your home sits on and the characteristics one can expect from soils of that type.
