Scope
What we test in Oklahoma City
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 Oklahoma City
Oklahoma City sits on expansive clay-rich soils that shift with seasonal moisture swings, and the region's freeze-thaw cycles — though milder than the northern plains — still demand concrete mix designs and placement practices that hold up across wide temperature ranges. Add the metro's active commercial, infrastructure, and energy-sector construction, and the stakes for defensible materials data are real. Our firm dispatches certified field technicians to Oklahoma City projects through our Dallas regional hub, covering fresh concrete testing, compressive strength cylinder breaks, aggregate gradation and quality, Proctor compaction, nuclear density gauge readings, soil classification, and soil corrosivity testing. Every test follows the applicable ASTM standard, every report is produced under a documented quality system, and results are delivered in a format your engineer of record, owner, or municipality can rely on without qualification. If your project requires scheduled or project-based coverage, we coordinate logistics in advance to keep your schedule intact.
Oklahoma's red-bed geology and high-plasticity clay soils mean accurate moisture-density relationships and soil classification — ASTM D698, D1557, D2487 — are critical before and during earthwork on most Oklahoma City sites. Hot, dry summers and occasional late-season cold fronts also create concrete placement windows that require documented fresh concrete temperature and slump testing to protect long-term strength.
FAQ · Oklahoma City
Oklahoma City projects often involve red clay subgrades. What testing do you perform to characterize those soils before earthwork begins?
We perform Atterberg limits testing (ASTM D4318) and unified soil classification (ASTM D2487) to identify plasticity and expansive potential in high-clay subgrades common to central Oklahoma. Paired with standard or modified Proctor testing (ASTM D698 or D1557) to establish moisture-density relationships, that data gives your geotechnical engineer and grading contractor a defensible baseline before any fill or structural earthwork begins.
Oklahoma summers get extremely hot. How does that affect concrete testing requirements on my project?
ACI 305R addresses hot-weather concrete production and placement. When ambient or concrete temperatures are elevated, fresh concrete testing — including temperature (ASTM C1064), slump (ASTM C143), air content (ASTM C231), and unit weight (ASTM C138) — becomes especially important for documenting that delivered concrete meets specification before placement. Our technicians record conditions and test at the point of discharge so your record is complete and defensible.
We have a project near the Oklahoma River corridor with potentially moisture-variable fill. Can you help us set compaction acceptance criteria?
Yes. We establish the maximum dry density and optimum moisture content through laboratory Proctor testing (ASTM D698 or D1557), then field technicians verify in-place compaction using a nuclear density gauge (ASTM D6938) referenced to that curve. Results are reported as percent compaction relative to the lab standard, giving your geotechnical engineer and inspector a consistent basis for acceptance or rejection decisions.
How fast can a technician be on site in Oklahoma City?
Oklahoma City 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 Oklahoma City, OK?
Field work in Oklahoma City is dispatched through the Dallas, TX regional hub, about 191 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Oklahoma City projects.
Are the technicians you send to Oklahoma City 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 Oklahoma agencies or owners require state-specific certifications, those are confirmed in the proposal.
