Finding the Root of The Problem


San Antonio isn’t known for high rainfall. Most precipitation occurs during the early fall and late spring, but the area typically gets less than 30 inches of total rainfall per year.

San Antonio is near the edge of the humid subtropical climate zone. The amount of humidity in each season can fluctuate depending on the influence of the Gulf of Mexico, in addition to the winds.

The soil composition in San Antonio, Texas and the surrounding cities such as New Braunfels, San Marcos, Uvalde and Seguin is made up of moderate to highly expansive types of soil. During and after periods of heavy rainfall, the soil absorbs the moisture and expands like a sponge, while the opposite is true during dry spells.

When rain is introduced to expansive soils, the dirt can start to lift up and put pressure on the home’s foundation, even as the center of the foundation stays dry.

During drought conditions, the moisture content from the soil gets released. As the soil shifts underneath the foundation, cracks can begin to develop inside the home.

Common Signs to Look for


Most homes in San Antonio have a slab-on-grade foundation. There are several signs to keep an eye out for that can indicate problems with this foundation type.

For example, you may start to see separations between the walls and ceilings or the floor. The same phenomenon may occur with your doors and windows. You might also notice that the doors and windows of your home begin sticking or not closing fully. Small cracks may appear near the doorframes.

Left untreated, these problems can worsen over time resulting in major structural damage.

Best Ways to Fix Foundation Problems

It’s important to contact a structural specialist immediately if you suspect problems with your foundation. When the issues are very serious, pilings are usually recommended to lift the home.

At Olshan we use a Hybrid Piling System designed to penetrate deeper than traditional methods, which is highly effective in the clay-rich soil that is common in the San Antonio region. Concrete lifting, another common repair, relies on injected polyurethane grout to raise the foundation as close as possible to its original level.
