What Causes Foundation Problems in San Antonio?
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.
Current San Antonio Soil Conditions
Dry stretches are when San Antonio foundations move the most. Below is the current U.S. Drought Monitor stage for Bexar County, updated weekly, alongside our overall risk rating for area soil. When the drought stage climbs, so does the stress on your foundation – and the value of catching movement early.

Common Signs of Structural Damage 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. Most concrete slab foundation problems originate from one or more of these five areas:
- Seasonal weather changes
- Poor drainage
- Expansive clay soil
- Trees and tree roots
- Under-slab plumbing leaks
Left unaddressed, these problems create visible damage to the home. For example, you may start to see separation 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 door frames.
Repairing Slab Foundation Homes – Cable Lock ST Plus
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 the Cable Lock ST Plus foundation repair system. It combines the durability of concrete pilings with the strength of steel to penetrate deeper than other pilings.
Cable Lock ST Plus (U.S. Patent #8,500,368) is highly effective in the clay-rich soil that is common in the San Antonio region.
Cable Lock ST Plus offers significant improvements in the quality of installation, cost-efficiency and long term reliability when compared to outdated foundation repair methods.

Verified Review of Olshan Foundation Repair San Antonio
★★★★★
Olshan repaired my foundation about 30 years ago and I recall the crew that came out to repair my foundation and the folks in the office were awesome! I have no issues after all these years. Fifteen years ago I had a room and patio added to my home and unfortunately, I have faced foundation problems. I called Olshan and everyone was great! Scarlett came out to assess my home and as she explained what, how and why I needed my foundation repaired, I felt really comfortable and immediately knew she was not trying to poke me in the eyes. She was awesome! The crew Joe Garcia, Gabriel Garcia, Caldelenio Carlos Soto and Joseph Clay were very hard at work. They walked me through the process both days!!! I am very pleased with Olshan. Costly but definitely a good lifetime investment, especially when it comes to the structure of your home! You get what you pay for! Thanks Olshan Team!!
