Scope
What we test in Green Bay
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 Green Bay
Green Bay's construction environment demands rigorous materials testing from the ground up — literally. The region's glacially deposited soils vary considerably in bearing capacity and frost sensitivity, and Wisconsin's climate puts concrete through significant seasonal stress, from cold-weather placement risks in late autumn through spring thaw conditions that can compromise subgrade stability. For contractors, developers, and engineers managing projects here — whether industrial facilities near the port, retail and mixed-use development, or roadway and infrastructure work — materials test data prepared for third-party review is not optional. It is the foundation of every structural decision, pay item dispute, and special inspection record. Dispatched through our Chicago regional hub, our ACI- and NICET-certified technicians provide scheduled field and laboratory testing of concrete, aggregate, and soil on a project-basis basis across Green Bay and the surrounding region. The laboratory operates under a documented quality system, and every report is produced to be technically defensible and clearly formatted for your project record.
Glacially derived fine-grained soils common to northeastern Wisconsin — including silts and clays with moderate to high frost susceptibility — make Proctor compaction baselines and in-place density verification critical steps before and during subgrade construction. Winter and early-spring concrete placements require particular attention to fresh concrete temperature requirements under ACI 306, given Green Bay's extended periods of below-freezing ambient temperatures.
FAQ · Green Bay
Can you perform cold-weather concrete testing during Wisconsin's winter construction season?
Yes. When ambient or material temperatures fall within the thresholds defined by ACI 306R, fresh concrete temperature measurement at point of discharge becomes especially critical. Our technicians record concrete temperature per ASTM C1064 on every field visit and note conditions relevant to cold-weather placement. That documentation supports your mix compliance record and helps substantiate any temperature-related decisions made on site.
Our Green Bay project has variable subgrade soils across the site. How do you establish the right compaction standard?
We run standard or modified Proctor tests — ASTM D698 or D1557 — on representative samples from your site to establish the maximum dry density and optimum moisture content for each distinct soil type encountered. If your subgrade changes character across cut areas, additional Proctor tests may be warranted. In-place compaction is then verified by nuclear gauge per ASTM D6938 or, where specified, by other approved methods.
What should I know about scheduling materials testing around Wisconsin's spring thaw period?
Spring thaw in northeastern Wisconsin can temporarily reduce subgrade bearing capacity as frozen moisture releases. We recommend scheduling density testing after subgrade conditions have stabilized rather than immediately post-thaw, and we can document in-place moisture alongside density readings per ASTM D6938 to give your project team a clearer picture of subgrade readiness before structural fill or slab placement proceeds.
How fast can a technician be on site in Green Bay?
Green Bay work is dispatched through our Chicago, IL 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 Green Bay, WI?
Field work in Green Bay is dispatched through the Chicago, IL regional hub, about 183 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Green Bay projects.
Are the technicians you send to Green Bay 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 Wisconsin agencies or owners require state-specific certifications, those are confirmed in the proposal.
