Scope
What we test in Corpus Christi
Concrete testing services
Fresh concrete sampled and tested at the pour — slump, air content, unit weight, and temperature — with cylinders and beams cast on site and broken in the laboratory on the schedule your specification calls for.
ASTM C172ASTM C143ASTM C231ASTM C173ASTM C138ASTM C1064ASTM C31ASTM C39
Aggregate testing services
Gradation, fines content, specific gravity and absorption, unit weight, abrasion resistance, and stockpile moisture for concrete, base course, and backfill aggregates.

Soil compaction and density testing
Standard and modified Proctor curves in the laboratory and in-place density by nuclear gauge on every lift, so fill, subgrade, and trench backfill are documented against the specified percent compaction.
Soil classification and index testing
Sieve and hydrometer gradation, Atterberg limits, moisture content, specific gravity, and USCS classification for earthwork acceptance, select-fill verification, and geotechnical reports.
ASTM D6913ASTM D7928ASTM D1140ASTM D4318ASTM D2216ASTM D854ASTM D2487
Soil corrosivity testing
pH and electrical resistivity of backfill for MSE walls, pipelines, and buried structures, reported against the specification limits for metallic and geosynthetic reinforcement.
Special inspection (IBC Chapter 17)
ICC-certified special inspectors for reinforced concrete and soils, reporting to the building official alongside the materials test results, so one agency covers both requirements.

Local conditions
Construction materials testing conditions in Corpus Christi
Corpus Christi's coastal location along the Gulf of Mexico creates a demanding environment for construction materials. Salt-laden air accelerates corrosion, high humidity and temperature swings affect concrete curing and set times, and the region's expansive and often poorly-draining soils require careful characterization before any foundation or pavement system is placed. On-shore and industrial construction along the Port of Corpus Christi, commercial development, and ongoing infrastructure work all carry specifications that depend on verified, defensible test data. Our firm dispatches certified field technicians from our Austin regional hub to Corpus Christi project sites for ASTM-compliant testing of concrete, aggregate, and soil. From fresh concrete sampling and cylinder fabrication to Proctor compaction curves, nuclear density, and soil classification, every test is performed under a documented quality system and reported in a format your engineer of record, project owner, and local authority can rely on.
Coastal Bend soils frequently include high-plasticity clays with significant shrink-swell potential, making accurate soil classification and compaction verification under ASTM D698, D1557, or D6938 especially important before slab and pavement placement. High ambient temperatures and humidity common to the Corpus Christi area can shorten concrete workability windows, reinforcing the value of timely fresh concrete testing performed in accordance with ASTM C172 and C1064.
FAQ · Corpus Christi
Corpus Christi soils near the bay seem to vary a lot — how do you determine which compaction standard applies to my project?
The applicable standard is typically set by the project specification or geotechnical report, not selected in the field. Our technicians can perform standard Proctor (ASTM D698) or modified Proctor (ASTM D1557) to establish the moisture-density relationship, then verify field compaction by nuclear gauge (ASTM D6938) or sand-cone (ASTM D1556) against that baseline. Your geotechnical engineer of record should designate which method governs.
Given the heat and humidity along the coast, how does weather affect when you schedule concrete testing visits?
High ambient temperatures accelerate cement hydration, shortening the time available between batching and placement. ASTM C1064 governs fresh concrete temperature measurement, and ASTM C172 requires sampling within specific time and discharge limits. We coordinate visit timing with your pour schedule so technicians are on site at first discharge. ACI 305R provides guidance on hot-weather concrete practices your team should also review with the mix designer.
The Port of Corpus Christi area has marine-influenced soils — do you test for soil corrosivity for underground utilities and structural elements?
Yes. Soil corrosivity testing typically includes pH, resistivity, chloride content, and sulfate content, using methods such as ASTM G57 for resistivity. Coastal and near-bay soils in this region can carry elevated chloride and sulfate concentrations that affect buried steel and concrete. Results are reported with the raw data so your engineer can evaluate corrosion risk and specify appropriate coatings, materials, or cathodic protection.
How fast can a technician be on site in Corpus Christi?
Corpus Christi work is dispatched through our Austin, TX regional hub. Scheduled visits are set up by phone at (346) 420-5425; multi-day placements and full-time project assignments are scheduled through a proposal request.
Which office covers materials testing in Corpus Christi, TX?
Field work in Corpus Christi is dispatched through the Austin, TX regional hub, about 172 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Corpus Christi projects.
Are the technicians you send to Corpus Christi certified?
Yes. Concrete technicians hold ACI Concrete Field Testing Technician Grade I; soils and laboratory technicians hold NICET Construction Materials Testing certifications; special inspection is performed by ICC-certified special inspectors. Where Texas agencies or owners require state-specific certifications, those are confirmed in the proposal.
