Construction Materials Testing in San Antonio, TX
San Antonio pours across two very different grounds: limestone and caliche on the north side, where fills are rocky and flex base rules the pavements, and Houston Black clay to the south and east, where moisture control decides whether a pad performs. The military installations, medical center expansion, and industrial growth on the south side add federal and owner-specific quality requirements to the mix. We run the program each setting requires: material-matched Proctors, in-place density per ASTM D6938, gradations on base and processed fills, and the concrete scope per ASTM C172, C143, C231, C1064, C31, and C39, with documentation built to survive a government submittal review.
Caliche and processed limestone fills on the north side need oversize-corrected density work, while Houston Black clay to the south is a moisture-conditioning problem; a single metro program has to run both correctly.
- Concrete field testing: slump, air content, temperature, and cylinder casting per ASTM C31
- Compressive strength testing of cylinders and cores per ASTM C39
- Soil compaction and in-place density by nuclear gauge per ASTM D6938
- Proctor moisture-density relationships per ASTM D698 / D1557
- Aggregate gradation, quality, and source testing per ASTM C136

FAQ · San Antonio
Can you meet military and federal project requirements?
Yes. Federal work adds submittal registers, certified reports, and quality documentation beyond typical commercial practice, and the testing program is set up to produce that record from the first lift rather than reconstructing it at closeout.
What is caliche and how do you test it?
A carbonate-cemented soil common across the north side. It compacts well but produces oversize particles that skew standard density methods, so testing uses the appropriate corrections and gradation checks to keep the numbers meaningful.
