About San Antonio GeoTech

San Antonio GeoTech is a geotechnical engineering and soil testing firm serving builders, developers, engineers, and property owners across the greater San Antonio area. We drill the borings, run the lab work, produce the reports, and give construction projects the subsurface data they need to move forward.

Our team works in the field every week across Bexar County and the surrounding region, from the clay corridors near I-35 to the limestone terrain north of Loop 1604. We know San Antonio’s soil, from Taylor Marl clay to Edwards Plateau limestone, the local permitting landscape, and what structural engineers in this market expect to see in a geotechnical report. We show up when we say we will, deliver reports on time, and answer the phone when you call.

Getting the soil right before construction starts is what keeps foundations performing and projects on track. That is the work we do, and we take it seriously.
