Scope
What we test in Fargo
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 Fargo
Fargo sits at the heart of the Red River Valley, one of the flattest and most expansive lake-bed plains in North America. The soils here — predominantly high-plasticity clays and silts deposited by glacial Lake Agassiz — present real challenges for compaction, bearing capacity, and frost-related movement. Winters that routinely push well below zero also demand careful attention to concrete placement temperatures, curing protection, and the timing of cylinder breaks. Add the region's active pace of commercial, industrial, and infrastructure development, and the need for rigorous, well-documented materials testing becomes clear. We dispatch certified field technicians to Fargo projects through our Minneapolis regional hub, providing ASTM-compliant testing of concrete, aggregate, and soil. Every test is performed to the applicable standard, every result is reported promptly, and every data point is defensible — giving contractors, developers, and engineers the documentation they need to keep projects moving and protect quality.
The fine-grained glaciolacustrine soils common across the Fargo area can be sensitive to moisture variation, making moisture-density relationship testing (ASTM D698 / D1557) and field compaction verification especially important for earthwork quality control. Fargo's extended freeze-thaw season also means concrete mix design, pour timing, and cold-weather curing practices should be supported by documented fresh concrete testing at the point of placement.
FAQ · Fargo
How do Fargo's clay-heavy soils affect the Proctor testing process for my project?
The high-plasticity clays and silts typical of the Red River Valley are sensitive to small changes in moisture content, which compresses the window between optimum and over-wet conditions. We establish the moisture-density relationship using ASTM D698 (Standard Proctor) or ASTM D1557 (Modified Proctor) depending on your specification, then verify field compaction with nuclear gauge testing per ASTM D6938. That baseline is essential — without it, field density results have no reliable reference.
Can you perform cold-weather concrete testing when temperatures drop below freezing on a Fargo pour?
Yes. Our technicians conduct fresh concrete testing — slump (ASTM C143), air content (ASTM C231), unit weight (ASTM C138), and concrete temperature (ASTM C1064) — regardless of ambient conditions. In cold weather, concrete temperature at point of delivery is a critical data point. ACI 306R provides cold-weather concrete guidance, and our field records document placement temperature so you have defensible evidence of compliance with your project's cold-weather plan.
How do you handle cylinder curing when a project site in Fargo has no heated storage during winter?
Freshly cast concrete test cylinders must be maintained between 60°F and 80°F for the first 24 hours per ASTM C31. When a heated curing box or insulated enclosure is not available on site, we document ambient conditions at the time of molding and advise the contractor on initial curing obligations. Cylinders are transported to our laboratory for standard curing and compression testing per ASTM C39 once the initial period requirements are met.
How fast can a technician be on site in Fargo?
Fargo 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 Fargo, ND?
Field work in Fargo is dispatched through the Minneapolis, MN regional hub, about 214 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Fargo projects.
Are the technicians you send to Fargo 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.
