Scope
What we test in Williams 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 Williams County
Williams County sits at the center of the Williston Basin, where energy infrastructure, industrial facility construction, and supporting civil work have driven consistent demand for dependable construction materials testing. Building here means dealing with northern Great Plains conditions: freeze-thaw cycles that stress concrete mixes and curing windows, native soils that can include highly plastic clays and variable fill from site to site, and project specifications written to enforce quality that holds up across wide temperature swings. Our firm dispatches certified technicians into Williams County on a scheduled and project-based basis to perform ASTM-compliant field and laboratory testing across concrete, aggregate, and soil scopes. From fresh concrete sampling and cylinder breaks to Proctor compaction curves, nuclear density verification, aggregate gradation, and soil corrosivity assessment, every service is delivered by ACI- and NICET-certified technicians and backed by a laboratory operating under a documented quality system — producing reports prepared for third-party review.
Soils in the Williston Basin region commonly include expansive clays and variable native materials that can make compaction control and subgrade evaluation critical steps before placing structural fill or pavement sections. Concrete placement in Williams County's climate demands attention to cold-weather and hot-weather practices per ACI 306 and ACI 305, given the region's wide seasonal temperature range.
FAQ · Williams County
How do cold winters in Williams County affect concrete testing and what standards govern cold-weather placements?
When ambient or concrete temperatures approach or fall below 40°F, cold-weather concrete practices per ACI 306R apply. Our technicians record fresh concrete temperature at point of discharge per ASTM C1064 and document conditions that could affect strength development. Cylinder curing and transport procedures are adjusted to prevent freezing of test specimens, which would invalidate break results. These field observations are recorded in the test report so the engineer of record has a defensible weather record.
What compaction testing is typically required for oil-field and industrial pad construction in Williams County?
Heavy industrial and energy-sector pads typically require moisture-density relationship testing per ASTM D698 or D1557 (Standard or Modified Proctor) to establish the compaction standard, followed by in-place density verification using nuclear gauge per ASTM D6938 or sand cone per ASTM D1556. The applicable method and required compaction percentage are usually set by the geotechnical report or project specification. Our technicians perform both the lab Proctor and field density testing.
How far in advance do I need to schedule a technician for a Williams County project?
Coverage for Williams County is dispatched through our Minneapolis regional hub, so advance scheduling is important to coordinate travel and technician availability. We recommend contacting our scheduling team as early as possible — ideally several business days ahead of a concrete pour or compaction inspection — to secure coverage. We do not guarantee same-day response for this location. For ongoing projects, standing schedules can be arranged to improve consistency and reduce coordination lead time.
How fast can a technician be on site in Williams County?
Williams County 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 Williams County, ND?
Field work in Williams County is dispatched through the Minneapolis, MN regional hub, about 538 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Williams County projects.
Are the technicians you send to Williams 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 North Dakota agencies or owners require state-specific certifications, those are confirmed in the proposal.
