Scope
What we test in Dallas County
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.
ASTM D75ASTM C136ASTM C117ASTM C127ASTM C128ASTM C29ASTM C131ASTM C566
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 Dallas County
Dallas County is one of the most active construction markets in the country, with dense urban infill, large-scale mixed-use development, highway and transit infrastructure, and a continuing wave of industrial and warehouse projects across cities like Irving, Garland, and Mesquite. The expansive, high-plasticity clay soils common throughout the Metroplex create real risk: fill that tests well one week can shift its moisture-density relationship after a rain event, and concrete placed in Texas summer heat requires careful attention to slump, air content, and set time to meet specification. Our firm dispatches certified field technicians from our Dallas regional hub to provide ASTM-compliant testing of concrete, aggregate, and soil — fresh concrete properties and cylinder breaks, aggregate gradation, Proctor compaction, nuclear density gauge readings, soil classification, and corrosivity testing — backed by a laboratory operating under a documented quality system and reports structured to satisfy engineer, owner, and agency review.
The high-plasticity clay soils prevalent across much of Dallas County are sensitive to seasonal moisture swings, making proper Proctor curve selection and field density verification critical on any project with engineered fill or subgrade preparation. Summer heat and low relative humidity can accelerate concrete stiffening on Dallas job sites, making timely fresh concrete testing per ASTM C172 and ASTM C1064 essential to catching out-of-spec conditions before placement is complete.
FAQ · Dallas County
Dallas County has a lot of expansive clay subgrade — how does that affect which compaction tests we need?
Expansive clays in Dallas County typically require Standard or Modified Proctor testing per ASTM D698 or ASTM D1557 to establish the correct moisture-density relationship for that specific material. Because high-plasticity clays can behave differently lot to lot, we run Proctor testing on representative samples rather than relying on a generic curve, so your nuclear density gauge readings in the field are compared against a defensible project-specific standard.
Can you handle both soil and concrete testing on the same visit to a Dallas County site?
Yes. Technicians dispatched from our Dallas hub can perform soil density testing with a nuclear gauge per ASTM D6938 and fresh concrete testing per ASTM C172, C143, C231, and C1064 on the same site visit when the project schedule allows it. Coordinating both services through a single dispatch reduces mobilization and simplifies the chain of custody for your project documentation.
What concrete mix and placement considerations should I flag for testing during Dallas summers?
High ambient temperatures accelerate hydration and can reduce slump rapidly between the truck and the point of placement. Technicians measure concrete temperature per ASTM C1064 at the point of delivery, and that reading is logged in the field report. If your specification includes a maximum placement temperature — common on TxDOT-influenced or owner-specified mixes — the test result documents whether that threshold was met at the time of placement.
How fast can a technician be on site in Dallas County?
Dallas County work is dispatched through our Dallas, 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 Dallas County, TX?
Field work in Dallas County is dispatched through the Dallas, TX regional hub. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Dallas County projects.
Are the technicians you send to Dallas County 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.
