Scope
What we test in Madison
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.

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 Madison
Madison's construction environment demands precision from the ground up. The region sits on a mix of glacial till, lacustrine clays, and bedrock that can vary significantly across a single site — conditions that make proper soil classification, moisture-density relationships, and compaction verification essential rather than optional. Seasonal extremes compound the challenge: Wisconsin winters compress the concrete placement window and make cold-weather protection a routine specification concern, while spring thaw cycles can disturb subgrade stability before a footing is ever formed. Our firm dispatches certified field technicians to Madison projects through our Chicago regional hub, providing scheduled and project-based coverage for contractors, developers, and engineers who need ASTM-compliant testing of concrete, aggregate, and soil. Testing is performed under a documented quality system, and reports are prepared for third-party review by city, county, and state agencies — giving project teams the documentation they need to stay on schedule and in spec.
Madison-area soils frequently include glacially deposited clays and silts that are sensitive to moisture variation, making Proctor compaction curves (ASTM D698 / D1557) and in-place density verification critical at every lift. Cold-weather concrete placements are common across Wisconsin's extended shoulder seasons, requiring fresh concrete temperature monitoring and mix compliance documentation consistent with ACI 306R guidelines.
FAQ · Madison
How do glacial soils in the Madison area affect the testing my project will need?
Glacial deposits common to the Madison region — including clays, silts, and mixed till — can have highly variable plasticity and moisture sensitivity. Expect soil classification per ASTM D2487 (Unified Soil Classification System), Atterberg limits testing per ASTM D4318, and moisture-density relationship testing per ASTM D698 or D1557 to be specified by your geotechnical engineer before earthwork acceptance testing begins.
What concrete testing is typically required during cold-weather placements in Wisconsin?
When ambient or forecast temperatures approach or drop below 40°F — common in Madison from October through April — ACI 306R cold-weather concreting protocols apply. Field technicians document fresh concrete temperature per ASTM C1064 alongside slump (ASTM C143), air content (ASTM C231), and unit weight (ASTM C138) at the point of placement, providing the time-stamped field data needed to demonstrate specification compliance.
City of Madison and Dane County projects reference specific compaction acceptance criteria — how do you handle those requirements?
Our technicians perform in-place density testing using nuclear density gauge methods per ASTM D6938, comparing results against the project-specific Proctor curve (ASTM D698 or D1557) established in the lab. Reports identify the test location, lift number, percent compaction achieved, and the governing specification value, giving your public agency inspector a clear, traceable record at each test point.
How fast can a technician be on site in Madison?
Madison 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 Madison, WI?
Field work in Madison is dispatched through the Chicago, IL regional hub, about 122 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Madison projects.
Are the technicians you send to Madison 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.
