Scope
What we test in Yellowstone 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 Yellowstone County
Yellowstone County sits at the intersection of the Yellowstone River valley and the northern high plains, where construction projects contend with expansive and frost-susceptible soils, significant freeze-thaw cycling, and concrete placement windows that can close quickly in spring and fall. A placement made at the wrong air or concrete temperature — or on fill that hasn't reached specified density — can compromise structural performance and trigger costly remediation. Our construction materials testing services give contractors, developers, and engineers in the Billings area the field and laboratory data they need to stay on spec and ahead of problems. Certified technicians dispatch from our Salt Lake City regional hub to perform ASTM-compliant fresh concrete testing and cylinder breaks, aggregate gradation and quality, Proctor and nuclear density testing, soil classification, and soil corrosivity analysis — all documented under a formal quality system and reported with the clarity prepared for third-party review or an agency review.
Soils across Yellowstone County commonly include alluvial and river-terrace deposits along the Yellowstone River corridor and variable native clays and silts on the surrounding benchlands that can exhibit shrink-swell behavior; both conditions make compaction verification and soil classification important early steps on any grading or foundation project. Montana's wide seasonal temperature range — including hard freezes well into spring and early fall — makes cold-weather concrete placement planning and temperature-monitored cylinder curing standard practice rather than exceptions.
FAQ · Yellowstone County
What scheduling lead time should I plan for when requesting field technicians in Yellowstone County?
Service for Yellowstone County is dispatched through our Salt Lake City regional hub, approximately 386 miles away. We ask project teams to schedule field visits in advance rather than assuming day-of availability. For recurring work — such as weekly compaction testing on a grading contract or regular concrete cylinder collection — a standing schedule reduces scheduling friction for all parties. Contact the hub directly to confirm available windows for your project calendar.
Montana winters and shoulder seasons create cold-weather concrete conditions — how does that affect cylinder curing and reporting?
When fresh concrete is placed at or near ACI 306 cold-weather thresholds, field-cured cylinders may not represent potential structural strength without supplemental standard-cured specimens. Our technicians collect and document both sets per ASTM C31, record placement and ambient temperatures, and note protection measures in field reports. That data gives engineers a defensible basis to evaluate whether a pour met temperature and curing requirements specified for the project.
How do you handle Proctor and density testing when native soils vary across a single Yellowstone County site?
When borrow or native material types change during grading, a single Proctor reference curve may not remain valid across the site. Our technicians flag material changes in the field, and additional ASTM D698 or D1557 Proctor tests are performed on representative samples of each distinct material. Nuclear density gauge readings under ASTM D6938 are then compared to the correct reference curve for each zone, keeping compaction verification defensible through project closeout.
How fast can a technician be on site in Yellowstone County?
Yellowstone County work is dispatched through our Salt Lake City, UT 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 Yellowstone County, MT?
Field work in Yellowstone County is dispatched through the Salt Lake City, UT regional hub, about 386 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Yellowstone County projects.
Are the technicians you send to Yellowstone 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 Montana agencies or owners require state-specific certifications, those are confirmed in the proposal.
