What we investigate in San Antonio

San Antonio sits at the head of Flash Flood Alley, where Gulf moisture climbing the Balcones Escarpment can dump intense rain onto shallow soils that shed it fast. Add expansive Houston Black clay under older foundations, and structural causes overlap. We document what actually failed, and a licensed engineer responds within 24 hours.

The conditions we see in San Antonio

San Antonio anchors what the San Antonio River Authority calls Flash Flood Alley: warm Gulf air lifts over the Balcones Escarpment and drops intense rain onto thin soils over limestone, so water runs off fast and rises fast. The city also runs hot and dry between those events, with 75 days over 100 degrees in 2023, and that swing punishes the ground under a foundation.

Below the surface, the older core sits on expansive Houston Black clay that shrinks in drought and swells with rain, moving slabs and post-and-beam foundations. About 22 percent of the city's housing predates 1960, carrying aged wiring and additions, while newer north-side subdivisions sit over the Edwards Aquifer recharge zone's faulted, cavernous karst limestone. Sorting clay movement, karst voids, and construction defects is the engineering question behind most claims.

How we help in San Antonio

The evaluations San Antonio cases usually call for

Foundation and structural evaluation

When a slab cracks or a wall separates here, the cause can be shrink-swell clay, a karst void on the recharge zone, a drainage problem, or a defect. Our licensed engineers evaluate the structure and the ground behavior together and document which one is responsible.

Our structural engineering in San Antonio
Flash flood and water loss investigation

After a flash flood, we determine what the water did to the structure and whether the damage came from the flooding, a pre-existing condition, or construction, based on the physical evidence. We investigate the component and drainage failures that surface in the aftermath.

Hail and storm damage

We evaluate hail and wind damage across San Antonio, separating fresh storm damage from wear, prior repairs, and conditions that predated the storm.

Fire origin & cause

Fire origin and cause in San Antonio

Cooking is the leading residential fire cause nationally, but San Antonio's pre-1960 housing core adds its own driver: decades-old wiring and distribution equipment buried behind additions and remodels. Add prolonged drought and brush that raises ignition risk across the surrounding Hill Country edge, and the origin of a fire is rarely obvious in the debris.

Our NAFI-certified investigators apply NFPA 921. They examine the scene systematically, trace burn patterns back to the area of origin, evaluate the electrical and mechanical systems, and eliminate causes until the evidence supports one conclusion, including whether the fire was accidental or incendiary. We preserve the evidence early, document the finding, and testify to it at deposition and trial.

Common questions

Forensic engineering in San Antonio, Texas

A different question about your case? An engineer, not a call center, answers within 24 hours.

Is foundation movement in San Antonio the clay or the karst?

It depends on the site. The older core sits on expansive Houston Black clay that shrinks and swells, while newer north-side ground overlies Edwards recharge-zone karst. We evaluate the pattern and the subsurface conditions to determine the cause rather than assume it.

Can you tell flash flood damage from a pre-existing condition?

Yes. Distinguishing fresh flood damage from prior deterioration or a defect is central to a San Antonio water claim, and we base the conclusion on the physical evidence at the property.

Do you charge travel to reach San Antonio?

No. We work San Antonio-area cases from our Omaha lab and Los Angeles office with no travel charges, and a licensed engineer responds within 24 hours.
