Scope
What we test in Campbell 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 Campbell County
Campbell County sits at the heart of Wyoming's Powder River Basin, where energy development, infrastructure expansion, and commercial construction operate against a backdrop of cold winters, freeze-thaw cycling, and soils that can vary considerably across relatively short distances. Concrete placed in northern Wyoming's shoulder seasons demands careful attention to temperature limits and curing practices, while compacted fill beneath foundations, pavements, and heavy industrial pads must meet verified density standards to perform under loaded conditions. Our firm dispatches certified field technicians from our Denver regional hub to serve Campbell County projects on a scheduled and project-based basis. In the field, our ACI- and NICET-certified technicians perform ASTM-compliant fresh concrete testing, cylinder fabrication, soil compaction verification, and aggregate sampling. Laboratory testing — including cylinder breaks, Proctor compaction, gradation, and soil classification — is completed under a documented quality system. Reports are structured for owner, engineer, and agency review.
Soils across the Powder River Basin can include expansive clays and variable alluvial materials that respond poorly to moisture change, making ASTM D698/D1557 Proctor testing and field density verification especially important before placing structural fill or pavement subgrade. Wyoming's extended cold-weather season also means fresh concrete testing must account for ACI 306R cold-weather concreting thresholds from late fall through early spring.
FAQ · Campbell County
How do you handle scheduling for a project in Gillette or rural Campbell County given the distance from your nearest hub?
Technician coverage for Campbell County is dispatched through our Denver regional hub, approximately 316 miles from Gillette. We coordinate visits on a scheduled and project-based basis, so early notice — ideally tied to your pour schedule or compaction milestone — allows us to confirm technician availability and travel logistics without delaying field work. We do not promise same-day dispatch from this hub.
What cold-weather concrete testing precautions apply to pours in Campbell County's fall and spring seasons?
When ambient or concrete temperatures approach the thresholds defined in ACI 306R, our technicians measure and record fresh concrete temperature per ASTM C1064 and note conditions that could affect cylinder curing. Cylinders must be protected from freezing during the initial curing period; we document field curing conditions and can flag situations where contractor-provided protection appears inadequate before cylinders are transported to the laboratory.
Can you perform Proctor and density testing on fill materials containing coarse particles common in some Wyoming aggregate sources?
Yes. When fill or subgrade material contains oversize particles, we apply the correction procedures outlined in ASTM D4718 before establishing the moisture-density relationship under ASTM D698 or D1557. Field density is then measured by nuclear gauge per ASTM D6938 or by other ASTM-referenced methods, with results corrected for oversize content so the compaction percentage reported reflects actual field conditions.
How fast can a technician be on site in Campbell County?
Campbell 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 Campbell County, WY?
Field work in Campbell County is dispatched through the Denver, CO regional hub, about 316 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Campbell County projects.
Are the technicians you send to Campbell 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.
