Scope
What we test in Great Falls
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 Great Falls
Great Falls sits at a continental crossroads where temperature swings of 50 degrees Fahrenheit or more in a single day are not unusual, and where spring and fall construction windows can tighten fast. Concrete placed in those conditions demands careful attention to temperature at delivery, air content, and slump before a single cylinder is cast. Beneath the pavement and foundations, soils across north-central Montana vary from river-deposited alluvials near the Missouri to stiffer native clays that respond unpredictably to freeze-thaw cycles. Getting the materials data right — on the day, on the pour, on the lift — protects the schedule and the structure. Our firm dispatches certified field technicians to Great Falls on a scheduled and project-based basis through our Salt Lake City regional hub. Testing spans fresh concrete properties, compressive strength cylinders, aggregate quality and gradation, Proctor compaction standards, nuclear density, soil classification, and soil corrosivity — all performed under a documented quality system with reporting built to hold up in the field and in the file.
North-central Montana's climate creates real risk for concrete work: cold-weather placements governed by ACI 306 and hot, dry summer conditions that can accelerate slump loss and set time both require field-verified mix data, not assumptions. Subgrade soils in the region can include frost-susceptible fines that make compaction verification under ASTM D6938 or ASTM D1557 particularly consequential for pavement and utility work.
FAQ · Great Falls
My concrete pour is scheduled in October when overnight temps in Great Falls can drop near freezing — what field testing applies and what should I track?
Cold-weather concrete work is governed by ACI 306R. At the point of discharge, technicians measure concrete temperature per ASTM C1064, slump per ASTM C143, air content per ASTM C231, and unit weight per ASTM C138. Temperature readings are recorded at placement and, when specified, during the protection period. Cylinders are field-cured under ASTM C31 procedures that account for ambient temperature, so your strength data reflects actual site conditions.
How far out should I schedule a technician for a Great Falls project, and what affects lead time?
Coverage for Great Falls is dispatched through our Salt Lake City regional hub. Scheduling at least several business days in advance is strongly recommended, especially during active construction season from late spring through early fall when demand across the region peaks. Project-based coverage — where we assign a technician to your pour or compaction schedule — is more reliable than last-minute requests. Contact the hub early when your project schedule firms up.
Cascade County and the City of Great Falls have their own public infrastructure projects — will your reports meet local agency submittal requirements?
Reports reference the specific ASTM test designation, revision year, sample identification, field conditions, and technician certification for each result. Most Montana DOT and local agency specifications cite standard ASTM methods — ASTM C39 for compressive strength, ASTM D1557 or D698 for Proctor, ASTM D6938 for in-place density — and our documentation is formatted to support those submittals. If your agency has a specific report format requirement, share it with us before mobilization.
How fast can a technician be on site in Great Falls?
Great Falls 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 Great Falls, MT?
Field work in Great Falls is dispatched through the Salt Lake City, UT regional hub, about 467 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Great Falls projects.
Are the technicians you send to Great Falls 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.
