Scope
What we test in Edmond
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 Edmond
Edmond sits on the rolling plains of central Oklahoma, where expansive clay soils and a climate that swings between hard freezes and intense summer heat create real challenges for construction quality assurance. Reactive soils can shift beneath slabs and footings if moisture content and compaction are not verified at every lift. Concrete placed during Oklahoma's temperature extremes — whether a January cold snap or an August afternoon above 95°F — demands careful attention to slump, air content, and set time to meet ACI 301 and project specifications. Our firm provides ASTM-compliant field and laboratory testing of concrete, aggregate, and soil for contractors, developers, and engineers active in Edmond and the broader Oklahoma City metro. Technicians holding ACI and NICET certifications are dispatched through our regional network, and all laboratory work is performed under a documented quality system. Reports are structured to support project documentation, pay applications, and regulatory submittals.
Central Oklahoma soils frequently include high-plasticity clays that are prone to volumetric change with moisture variation, making Proctor compaction baselines and field density verification — tested per ASTM D698, D1557, or ASTM D6938 — particularly consequential for earthwork and pavement subgrade. Concrete scheduling in this climate should account for both cold-weather protection requirements and the hot, dry conditions that can accelerate slump loss and shorten finishing windows during summer months.
FAQ · Edmond
Oklahoma clay can shift seasonally — what soil testing do you recommend before we start earthwork on a commercial site in Edmond?
We typically recommend soil classification per ASTM D2487 (Unified Soil Classification System), Proctor compaction testing per ASTM D698 or D1557 to establish moisture-density relationships, and Atterberg limits per ASTM D4318 to characterize plasticity. For sites with significant fill or pavement subgrade, California Bearing Ratio (ASTM D1883) may also be warranted. These results give your geotechnical engineer and grading contractor the baselines needed to specify and verify acceptable compaction.
How do you handle concrete testing scheduling for Edmond projects given that your nearest hub is in Dallas?
Coverage for Edmond is dispatched through our Dallas regional hub. We work with project teams to schedule field visits around pour schedules confirmed in advance. We do not guarantee same-day dispatch, so coordinating concrete placement dates with our scheduling team at least 24 to 48 hours ahead is strongly recommended. This lead time allows us to assign a certified ACI field technician and confirm arrival before your truck is on site.
What concrete tests are performed on site during a pour, and which ASTM methods govern them?
During a fresh concrete visit, our ACI-certified technicians perform temperature measurement (ASTM C1064), slump (ASTM C143), air content by pressure meter (ASTM C231), unit weight (ASTM C138), and fabrication of compressive strength cylinders (ASTM C31). Cylinders are cured and broken at specified ages per ASTM C39. Field results and break data are documented in reports that directly reference the applicable ASTM designation and your project specification requirements.
How fast can a technician be on site in Edmond?
Edmond 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 Edmond, OK?
Field work in Edmond is dispatched through the Dallas, TX regional hub, about 202 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Edmond projects.
Are the technicians you send to Edmond 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.
