Scope
What we test in Norman
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 Norman
Norman sits on the southern edge of the broader Oklahoma City metro, where active construction spans university-related facilities, residential subdivisions, commercial development along major corridors, and expanding infrastructure to support steady population growth. The region's expansive clay soils — common throughout central Oklahoma — are prone to significant volume change with moisture fluctuation, making rigorous subgrade verification and compaction documentation essential before any slab, pavement, or structural foundation goes down. Oklahoma's climate adds further pressure: wide temperature swings and periodic freeze-thaw events demand that concrete placement be managed carefully and that cylinders be made and cured correctly from the start. Our firm dispatches certified field technicians to Norman project sites on a scheduled and project-based basis through our Dallas regional hub. We perform ASTM-compliant testing of soil, aggregate, and concrete — from Proctor and nuclear density to fresh concrete testing and cylinder breaks — and deliver defensible reports backed by a documented laboratory quality system.
Central Oklahoma's native soils are predominantly high-plasticity clays that swell and shrink with seasonal moisture changes, making accurate soil classification and moisture-density relationships under ASTM D698 or D1557 critical groundwork for any project in the Norman area. Summer heat and low humidity can accelerate concrete setting times in the field, reinforcing the importance of consistent fresh concrete testing at point of discharge in accordance with ASTM C172 sampling procedures.
FAQ · Norman
Norman has expansive clay soils — what testing do you perform to characterize subgrade before we build?
For projects on central Oklahoma's high-plasticity clays, we perform Atterberg limits testing (ASTM D4318), grain-size analysis (ASTM D6913 / D7928), and USCS soil classification (ASTM D2487). These results define shrink-swell potential and inform subgrade treatment design. Moisture-density relationships are then established via Standard or Modified Proctor (ASTM D698 or D1557) so field compaction targets are grounded in tested data, not assumptions.
How do you handle scheduling for Norman projects given your nearest hub is in Dallas?
Technician visits to Norman are coordinated through our Dallas regional hub and are scheduled in advance on a project-based basis. We work with project superintendents and engineers to align field visits with concrete pours, earthwork lifts, and inspection milestones. We do not promise same-day dispatch; building advance scheduling into your project timeline ensures coverage without delays.
Oklahoma summers are hot — can extreme heat affect how you sample and test fresh concrete on our Norman pour?
Yes. High ambient temperatures accelerate cement hydration, compressing the window for sampling and testing. ASTM C172 requires sampling within defined time limits, and ASTM C31 specifies that cylinders be made and initially cured on-site under controlled conditions. Our technicians follow these procedures rigorously and note air temperature, concrete temperature, and time of sampling on every field record — documentation that matters if mix performance is later questioned.
How fast can a technician be on site in Norman?
Norman 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 Norman, OK?
Field work in Norman 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 Norman projects.
Are the technicians you send to Norman 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.
