Scope
What we test in Missoula 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 Missoula County
Missoula County sits in a mountain valley where the Clark Fork River and converging drainages have deposited a varied mix of alluvial soils, glacial materials, and decomposed granitic residuum. Combined with Montana's wide seasonal temperature swings — freeze-thaw cycles that stress fresh concrete placements and complicate compaction windows — responsible construction here demands rigorous materials testing, not estimations. We provide ASTM-compliant field and laboratory testing of concrete, aggregate, and soil for contractors, developers, and engineers working on projects throughout Missoula County. Our ACI- and NICET-certified field technicians handle fresh concrete testing, cylinder casting and breaks, aggregate gradation and quality, Proctor compaction and nuclear density gauging, soil classification, and soil corrosivity evaluation. Work is dispatched through our regional hub network and executed under a documented quality system, so every result is traceable, defensible, and formatted to satisfy specification submittals and agency review.
Missoula County's mix of alluvial valley soils and steeper colluvial and glacially influenced materials means subgrade conditions can vary significantly across a single site, making structured sampling and ASTM D1557 or D698 Proctor programs essential rather than optional. Montana's shoulder-season temperature extremes — including the risk of overnight freezing well into spring and fall — require concrete placements to be monitored closely for air content and temperature compliance per ACI 305R and ACI 306R guidance.
FAQ · Missoula County
What soil conditions in Missoula County should I expect to affect compaction testing?
The valley floor around Missoula includes alluvial silts, sands, and gravels deposited by the Clark Fork system, while upland and hillside cuts often encounter decomposed granite or colluvial material. Both categories can behave differently under compaction. We establish site-specific moisture-density relationships per ASTM D1557 or ASTM D698 before field density testing begins, so the nuclear or sand-cone comparisons are referenced to an accurate baseline.
How do Montana's cold seasons affect concrete cylinder curing and break schedules?
Cylinders cast in cold-weather conditions must be protected from freezing during the initial cure period per ASTM C31 requirements. Our technicians record placement temperature at the time of casting and follow initial curing protocols accordingly. Cylinders are transported to the laboratory where curing conditions are controlled. If your spec requires cold-weather monitoring per ACI 306R, we document ambient and concrete temperatures at the time of sampling.
Can you perform aggregate testing on locally sourced pit run or quarry material common to western Montana?
Yes. We test aggregate from local pit run, crushed stone, or quarry sources against project specifications using ASTM C136 for gradation, ASTM C131 or C535 for Los Angeles abrasion resistance, ASTM C88 for soundness, and ASTM C142 for clay lumps and friable particles. Results are reported against the applicable spec limits so your material approval submittal has a clear pass or fail basis.
How fast can a technician be on site in Missoula County?
Missoula County work is dispatched through our Seattle, WA 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 Missoula County, MT?
Field work in Missoula County is dispatched through the Seattle, WA regional hub, about 394 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Missoula County projects.
Are the technicians you send to Missoula 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.
