San Marcos Soil Characteristics As They Affect Foundation Repair
According to the United States Census Bureau, San Marcos has a total area of 18.3 square miles of which only 0.1 square miles (0.60%) is surface water. The city rests upon the Balcones Fault, which is known as the boundary between the Gulf Coastal Plains and the Texas Hill Country. The fault has created opportunities for ground water to rise to the surface and form crystal clear fresh water springs. The San Marcos River is the most well known of the water systems in the area.
The eastern portion of San Marcos is generally flat or rolling terrain that is blackland prairie suitable for farming. This is the western most portion of the Gulf Coastal Plains area and the soils are characterized by a high clay content. Clay soils are the culprit behind soil movement. This occurs when the moisture content of the clay changes because clay will expand when wet and shrink when dry. When the climate is wet the clay soils will swell in volume and when the climate is dry the clay soils will shrink in volume. This constant shrinking and swelling places tremendous stresses on rigid concrete slab foundations. When the stresses are too great, the slab foundation, or a portion of it, will uplift, collapse, and/or crack.
The western portion of San Marcos marks the beginning of the rocky Texas Hill Country with larger rolling hills. Generally these areas have a higher concentration of rocky soil and a lower concentration of clay soils. As a result, these areas are less prone to soil movement and foundation damage.
