Scope
What we test in Natrona 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 Natrona County
Natrona County sits in the high plains and foothill terrain of central Wyoming, where construction contends with expansive and variable native soils, freeze-thaw cycles that can exceed 100 episodes per year at Casper's elevation, and wind-driven temperature swings that compress workable concrete placement windows to a narrow range. Oil and gas infrastructure, commercial development along Casper's growth corridors, and public works projects all depend on materials that perform under those conditions — and on documentation prepared for third-party review. Our firm dispatches certified field technicians to Natrona County project sites for ASTM-compliant testing of concrete, aggregate, and soil. Work is scheduled and coordinated through our Denver regional hub. Field technicians carry ACI and NICET certifications, and the laboratory operates under a documented quality system. Reports are structured to be defensible at every stage of project delivery.
Soils across Natrona County commonly include wind-deposited silts and mixed alluvial materials that can vary significantly in plasticity and compaction behavior over short distances, making classification and Proctor testing important early in grading operations. Wyoming's cold winters and short frost-free season require particular attention to cold-weather concrete practices per ACI 306 and to the timing of nuclear density and lab testing around frozen or near-frozen ground conditions.
FAQ · Natrona County
What soil classification testing do you perform, and why does it matter for Natrona County projects?
We perform grain-size analysis (ASTM D6913), hydrometer analysis (ASTM D7928), Atterberg limits (ASTM D4318), and USCS classification (ASTM D2487). In Natrona County, native soils can shift from well-graded gravels to low-plasticity silts within a single site, and proper classification drives compaction specification selection, subgrade treatment decisions, and earthwork acceptance criteria — all of which affect long-term pavement and structure performance.
How do Wyoming's cold winters affect concrete cylinder curing and when testing can be scheduled?
Fresh concrete cylinders must be protected from freezing during the initial 24-hour curing period per ASTM C31. In Natrona County's cold months, field technicians assess ambient and concrete temperatures at placement and document protection measures. Cylinders are transported under temperature-controlled conditions to the laboratory. ACI 306R guidance on cold-weather concreting informs our technicians' field observations, and placement conditions are recorded in the test report.
Can you perform Proctor testing before we mobilize, so the compaction specification is set before grading begins?
Yes. Submit representative bulk samples of your proposed fill or subgrade material ahead of grading. We run standard or modified Proctor compaction testing (ASTM D698 or ASTM D1557) in the laboratory and return maximum dry density and optimum moisture content values. Having that baseline before equipment mobilizes to a Natrona County site eliminates the common problem of nuclear gauge density readings with no valid reference curve to check against.
How fast can a technician be on site in Natrona County?
Natrona County work is dispatched through our Denver, CO 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 Natrona County, WY?
Field work in Natrona County is dispatched through the Denver, CO regional hub, about 227 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Natrona County projects.
Are the technicians you send to Natrona 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 Wyoming agencies or owners require state-specific certifications, those are confirmed in the proposal.
