Scope
What we test in Cleveland 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 Cleveland County
Cleveland County sits at the intersection of rapid suburban growth and demanding subsurface conditions. The Norman and Moore corridors are adding residential subdivisions, commercial pads, and municipal infrastructure at a sustained pace, while the underlying soils — often expansive clays common to central Oklahoma — require careful attention during earthwork and foundation construction. Seasonal temperature swings also put concrete mix design and curing under real pressure: summer heat accelerates set times and risks plastic-shrinkage cracking, while late-season work demands close monitoring of cold-weather placement. These are not abstract concerns; they show up directly in compaction failures, failing cylinder breaks, and costly rework when testing is absent or poorly documented. Our firm dispatches certified field technicians through our Dallas regional hub to provide ASTM-compliant testing of concrete, aggregate, and soil — with reporting prepared for third-party review. Scheduled and project-based coverage keeps your testing program on track without disrupting your schedule.
Central Oklahoma's prevalence of high-plasticity clay soils means moisture-density relationships established during Proctor testing (ASTM D698 / D1557) can shift meaningfully with seasonal rainfall, making field density verification against the correct reference curve especially important on earthwork-intensive projects. Concrete placement during Oklahoma's hot summers warrants close monitoring of fresh concrete temperatures and slump under ASTM C1064 and C143 to protect long-term strength outcomes.
FAQ · Cleveland County
Our Cleveland County site has highly plastic clay. What soil testing do we need before we can start grading?
At minimum, expect moisture-density relationship testing (ASTM D698 standard Proctor or ASTM D1557 modified Proctor, selected based on your project specification) and Atterberg limits (ASTM D4318) to classify plasticity. Swell potential and soil classification under ASTM D2487 are also common on central Oklahoma sites. These results establish the compaction targets and handling conditions your earthwork contractor must meet.
How do you handle nuclear density gauge testing on Oklahoma DOT or City of Norman projects that reference specific compaction specs?
Our NICET-certified technicians operate calibrated nuclear gauges under ASTM D6938, correlating field density readings to the project-specific Proctor curve required by the governing specification — whether that is ODOT standard specifications or a municipal public-works requirement. We document gauge calibration, test location, and lift depth on every report so the data is directly defensible against the spec language your inspector will cite.
With Oklahoma summers routinely exceeding 90°F, what concrete testing precautions apply on our Cleveland County pours?
ACI 305R guidelines for hot-weather concreting apply when ambient or concrete temperatures are elevated. Field technicians measure fresh concrete temperature (ASTM C1064) alongside slump (ASTM C143), air content (ASTM C231), and unit weight (ASTM C138) at point of discharge. Elevated temperatures that approach specification limits are documented and flagged in the field report so the placing contractor and engineer of record can act before strength is compromised.
How fast can a technician be on site in Cleveland County?
Cleveland 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 Cleveland County, OK?
Field work in Cleveland County is dispatched through the Dallas, TX regional hub, about 173 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Cleveland County projects.
Are the technicians you send to Cleveland 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 Oklahoma agencies or owners require state-specific certifications, those are confirmed in the proposal.
