Scope
What we test in Casper
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 Casper
Casper sits at the center of Wyoming's energy and infrastructure economy, where wind-scoured winters, wide temperature swings, and soils that can carry expansive clays or variable bedrock conditions all affect how construction materials perform in the field. A concrete pour that looks clean in August can be undermined by inadequate air entrainment heading into a hard freeze; compaction gains made in dry weather can mask moisture sensitivity that shows up after spring thaw. Contractors, developers, and engineers working in the Natrona County area need materials testing prepared for third-party review — from WYDOT submittals to owner and engineer review. Our certified technicians cover Casper on a scheduled and project-based basis, dispatched through our Denver regional hub, performing ASTM-compliant field and laboratory testing of concrete, soil, and aggregate under a documented quality system. Reports are written to be defensible, not just delivered.
Wyoming's high-plains soils frequently include fine-grained, moisture-sensitive materials that require careful Proctor moisture-density relationships and field density verification — particularly important on projects where freeze-thaw cycling can expose compaction deficiencies. Concrete work in the Casper area should account for the region's wide diurnal temperature range and the cold-weather concreting requirements of ACI 306.
FAQ · Casper
How do Wyoming's cold winters affect concrete testing requirements on my Casper project?
When ambient or concrete temperatures fall near or below 40°F, ACI 306R cold-weather concreting practices apply. Our technicians verify fresh concrete temperature per ASTM C1064 at the point of placement and note conditions that trigger protection requirements. Cylinder curing becomes critical: field-cured cylinders must be protected from freezing, and the handling record travels with every specimen to the laboratory.
What soil classification and Proctor testing do you perform for earthwork on Wyoming projects?
We perform USCS and AASHTO soil classification, Atterberg limits per ASTM D4318, and standard or modified Proctor compaction testing per ASTM D698 or D1557 depending on project specification. For projects with fine-grained or mixed soils common to the high-plains region, getting the correct Proctor curve established early prevents disputes during field density verification later.
Can you handle nuclear density gauge testing for earthwork and subgrade compaction in Casper?
Yes. Technicians qualified under NICET perform in-place density testing using nuclear methods per ASTM D6938. All gauge operators comply with NRC and DOT radioactive materials handling requirements. Results are compared against the project-specific Proctor reference and reported promptly so earthwork can proceed without unnecessary hold time.
How fast can a technician be on site in Casper?
Casper 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 Casper, WY?
Field work in Casper 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 Casper projects.
Are the technicians you send to Casper 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.
