Scope
What we test in Minot
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 Minot
Minot's climate puts real demands on construction materials. Temperatures swing from well below zero in winter to hot, dry summers, compressing the workable concrete season and stressing soil moisture conditions that directly affect compaction results. The region's glacial till and expansive clay soils common across north-central North Dakota require careful Proctor establishment and field density verification — skipping that step invites settlement and pavement failure. On top of that, oil-patch industrial growth and ongoing infrastructure work across the region mean project specifications carry real consequences. Our technicians perform ASTM-compliant field and laboratory testing of concrete, aggregate, and soil — fresh concrete testing, cylinder breaks, aggregate gradation, soil classification, Proctor compaction curves, nuclear density gauge readings, and soil corrosivity analysis — working under a documented quality system and returning defensible reports your project team can act on. Coverage for Minot is dispatched through our Minneapolis regional hub on a scheduled and project-based basis.
North-central North Dakota commonly features glacial till and cohesive clay soils that are sensitive to moisture variation, making Proctor moisture-density relationships and field compaction verification especially critical. Minot's severe freeze-thaw cycle also affects concrete mix design decisions and the timing of cylinder curing and break schedules.
FAQ · Minot
Concrete pours in Minot can happen in near-freezing conditions in spring and fall — how does cold weather affect your fresh concrete testing process?
When ambient or concrete temperatures approach or fall below 50 °F, ACI 306 cold-weather concreting practices become relevant to mix evaluation. During fresh concrete testing per ASTM C172 (sampling) and ASTM C1064 (temperature), our technicians record concrete temperature as a primary data point. Cylinder specimens are protected from freezing during initial curing per ASTM C31, and any deviation from standard curing conditions is documented in the report so the engineer of record can assess strength implications.
North Dakota winters shut down earthwork for months — when should we schedule Proctor testing relative to our spring construction start?
Proctor moisture-density testing under ASTM D698 (standard effort) or ASTM D1557 (modified effort) should be completed before active earthwork begins, not after. If your borrow source or subgrade material hasn't been characterized from a prior season, plan for lab turnaround time before your first compaction lift. Scheduling through our Minneapolis hub in early spring ensures field technicians and lab capacity are aligned with your mobilization date.
Our Minot project involves expansive or high-plasticity soils — what soil classification testing do you perform to characterize them?
We perform Atterberg limits testing (ASTM D4318) to determine liquid limit and plasticity index, grain-size analysis by sieve (ASTM D6913) and hydrometer (ASTM D7928) where fines are significant, and USCS classification per ASTM D2487. These results inform Proctor test selection, subgrade treatment decisions, and geotechnical recommendations. High plasticity index values are a flag for potential swell behavior that your geotechnical engineer should address in the foundation or pavement design.
How fast can a technician be on site in Minot?
Minot work is dispatched through our Minneapolis, MN 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 Minot, ND?
Field work in Minot is dispatched through the Minneapolis, MN regional hub, about 442 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Minot projects.
Are the technicians you send to Minot 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 North Dakota agencies or owners require state-specific certifications, those are confirmed in the proposal.
