Scope
What we test in Oakland 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 Oakland County
Oakland County sits at the intersection of sustained residential expansion, large commercial development, and significant public infrastructure investment — all of it subject to Michigan's pronounced freeze-thaw cycle and a subsurface that transitions from glacially deposited clays and silts in lower elevations to sandy loams and gravels further north. Those conditions make materials testing a structural and schedule issue, not just a compliance formality. Concrete placed in spring or late fall must be documented against ACI 305 and ACI 306 temperature thresholds. Earthwork on clay-bearing subgrades demands accurate Proctor baselines and reliable compaction verification before any pavement or foundation load is applied. Our firm dispatches certified field technicians to Oakland County projects from our Detroit-area regional hub, covering scheduled and project-based assignments for contractors, developers, and engineers who need defensible data, consistent procedures, and reports prepared for third-party review.
Oakland County's glacially derived soils — ranging from soft lacustrine clays to well-graded glacial outwash gravels — mean that moisture sensitivity and variability across a single site are common concerns, making thorough soil classification and Proctor testing practical necessities rather than optional steps. Michigan's extended winters and significant freeze-thaw activity also create real concrete placement windows that require documented temperature monitoring and proper curing verification to meet specification.
FAQ · Oakland County
What soil classification work is typically needed at the start of an Oakland County earthwork project?
Most Oakland County projects begin with ASTM D2487 (Unified Soil Classification System) testing to characterize subgrade materials, which can range from compressible clays to granular glacial deposits within a short distance. Atterberg limits (ASTM D4318) and moisture-density relationships (ASTM D698 or D1557) are typically run before grading begins so the compaction specification is tied to actual site materials rather than assumed values.
How do Michigan's freeze-thaw seasons affect when and how you perform compaction testing on our site?
Frozen or frost-affected soil cannot be compacted to specification and cannot be reliably tested with a nuclear gauge (ASTM D6938) or sand cone (ASTM D1556). Testing is scheduled around active placement only, and technicians document ambient and material temperatures. In spring, previously frozen subgrade that has thawed but not dried to near-optimum moisture will commonly fail density requirements and needs additional drying or remediation before testing resumes.
What concrete testing is required for flatwork or structural pours placed in Oakland County's colder months?
Cold-weather concrete work in Michigan requires fresh concrete temperature documentation at point of discharge per ASTM C1064, alongside slump (ASTM C143), air content (ASTM C231), and cylinder fabrication (ASTM C31). ACI 306R sets the framework for cold-weather protection requirements. Technicians record concrete and ambient temperatures, and minimum placement temperatures are typically specified by the engineer of record. Cylinders are initial-cured under controlled conditions per ASTM C31 to avoid compromised breaks.
How fast can a technician be on site in Oakland County?
Oakland County work is dispatched through our Detroit, MI 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 Oakland County, MI?
Field work in Oakland County is dispatched through the Detroit, MI regional hub, about 29 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Oakland County projects.
Are the technicians you send to Oakland 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 Michigan agencies or owners require state-specific certifications, those are confirmed in the proposal.
