Scope
What we test in Laramie 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 Laramie County
Laramie County sits on the high plains of southeast Wyoming, where elevations above 6,000 feet, persistent wind, and wide temperature swings create real construction challenges. Concrete placed during spring or fall shoulder seasons can face freezing temperatures within hours of finishing, making proper fresh concrete testing — slump, air content, unit weight, and temperature per ASTM C172 — essential rather than optional. The native soils across the county range from wind-deposited silts to expansive clays and gravelly alluvium, meaning subgrade verification is not a formality; it directly affects pavement, slab, and foundation performance. Our certified field technicians, dispatched through our Denver regional hub, perform ASTM-compliant concrete, aggregate, and soil testing on commercial, infrastructure, and residential projects throughout Laramie County. The laboratory operates under a documented quality system, and every report is structured to be defensible to the Wyoming Department of Transportation, local jurisdictions, and project engineers without requiring follow-up calls to interpret the data.
Soils in the Laramie County area frequently include fine-grained, wind-reworked deposits and pockets of expansive clay that warrant careful classification and moisture-density testing before earthwork acceptance. Wyoming's high-elevation climate compresses the practical concrete placement season and makes cold-weather and hot-weather concrete procedures — per ACI 305R and ACI 306R — a routine consideration on almost any project.
FAQ · Laramie County
Wyoming DOT projects require specific testing frequencies — can you meet WYDOT's materials testing plan requirements?
Yes. We structure testing frequencies and documentation to align with the project's materials testing plan, whether it references WYDOT standard specifications or project-specific requirements. Our technicians perform field tests per the applicable ASTM designations — including ASTM C172 for concrete sampling and ASTM D6938 for nuclear density — and reports are formatted to support WYDOT submittals and documentation packages.
How do you handle cold-weather concrete testing on Laramie County projects where temperatures can drop fast?
Our technicians record concrete temperature at point of discharge per ASTM C1064 on every visit. When ambient or forecast conditions trigger cold-weather thresholds defined in ACI 306R, that data is captured in the field report and flagged. This gives the contractor and engineer documented evidence of placement conditions and supports decisions about protection measures — which is exactly what an RFI or dispute resolution needs.
What soil classification tests do you run, and why does that matter for Cheyenne-area subgrades?
We perform ASTM D2487 (USCS classification) and ASTM D4318 (Atterberg limits) to identify plastic, expansive, or frost-susceptible soils. In the Laramie County area, fine-grained and potentially expansive soils are common enough that classification testing before earthwork acceptance is a practical safeguard against differential settlement and pavement distress — not just a specification checkbox.
How fast can a technician be on site in Laramie County?
Laramie 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 Laramie County, WY?
Field work in Laramie County is dispatched through the Denver, CO regional hub, about 97 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Laramie County projects.
Are the technicians you send to Laramie 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.
