Forensic Engineering in San Antonio, TX

Forensic work in San Antonio follows the geology like everything else here. On the clay side, the cases are heave and differential movement, slabs riding Houston Black through wet and dry years. On the limestone side, they are mixed bearing, fill wedges against rock, and the occasional karst surprise. We investigate from evidence: floor elevation surveys to map the movement, cores per ASTM C42 to establish the in-place concrete, borings beneath the distress to identify what the structure actually bears on, and petrographic examination per ASTM C856 where the concrete itself is in question. Chain of custody is maintained, and licensed engineers are engaged for evaluation and testimony.

Movement patterns tell the story here: uniform seasonal cycling points to clay behavior, sharp localized offsets point to mixed bearing or fill transitions, and the elevation survey is what distinguishes them before anyone commits to a theory.
