Scope
What we test in Aurora
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 Aurora
Aurora sits on glacially deposited soils — a mix of clays, silts, and sands left by retreating ice sheets — that can shift significantly with seasonal freeze-thaw cycles and moisture changes. For contractors and developers working across Kane and DuPage Counties, that means soil variability and expansive clay behavior are routine concerns on every graded site, foundation pour, or pavement section. Illinois winters also compress the usable window for concrete placement, making fresh concrete testing and temperature monitoring during cold-weather pours a practical necessity rather than a formality. Our firm dispatches certified field technicians to Aurora project sites through our Chicago regional hub, providing ASTM-compliant testing of concrete, aggregate, and soil. From Proctor compaction curves and nuclear density verification to fresh concrete testing and cylinder breaks, every assignment runs under a documented quality system and closes with clear, defensible reporting that satisfies engineer-of-record requirements and local agency submittals.
Glacially derived clay-rich soils common to the Aurora area can exhibit low bearing capacity and volume change with moisture variation, making soil classification and compaction verification under ASTM D698, D1557, or D6938 important controls at every earthwork phase. Illinois's extended cold season — with ground freezing and thaw cycles that typically run from late November through early April — creates concrete placement conditions that require documented fresh-concrete temperature and air-entrainment testing to meet ACI 306 cold-weather requirements.
FAQ · Aurora
My Aurora project has expansive clay subgrade. What testing do you run to characterize it before we compact structural fill?
For clay subgrade characterization, we perform Atterberg limits testing (ASTM D4318), grain-size analysis (ASTM D6913 and D7928), and soil classification under ASTM D2487. Those results define plasticity index and swell potential, which your geotechnical engineer uses to specify compaction criteria, moisture conditioning requirements, and whether select fill or stabilization is warranted before structural loading.
We're placing concrete in November in Aurora. What field tests are required to document a cold-weather pour?
For cold-weather placements, our ACI-certified technicians measure fresh concrete temperature (ASTM C1064), slump (ASTM C143), air content (ASTM C231 or C173), and unit weight (ASTM C138) at point of discharge. Cylinder sets are cast per ASTM C31, which specifies initial curing temperature ranges. Documentation of these values supports your ACI 306-referenced cold-weather protection plan and gives the engineer of record a defensible record.
The City of Aurora plan reviewer is asking for compaction test reports tied to specific lifts. How do your reports handle that?
Each nuclear gauge density test report (ASTM D6938) includes station or grid location, lift number, test depth, field dry density, field moisture, the reference Proctor maximum dry density (ASTM D698 or D1557 as specified), and the resulting percent compaction. Reports are structured so plan reviewers and inspectors can match results to grading plan stationing or structural element locations without ambiguity.
How fast can a technician be on site in Aurora?
Aurora 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 Aurora, IL?
Field work in Aurora is dispatched through the Chicago, IL regional hub, about 36 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Aurora projects.
Are the technicians you send to Aurora 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 Illinois agencies or owners require state-specific certifications, those are confirmed in the proposal.
