Scope
What we test in Waukesha 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 Waukesha County
Waukesha County sits on a mix of glacially deposited soils — clays, silts, sands, and gravels left behind by the last ice age — that vary sharply across even short distances. That variability means fill performance is rarely uniform, concrete placement schedules get compressed by Wisconsin's hard winters and short construction seasons, and structural decisions depend on data collected under real field conditions. Contractors, developers, and engineers working on commercial, residential, and infrastructure projects across the county need test results they can defend to local reviewers and keep the schedule moving. Our ACI- and NICET-certified field technicians dispatch to Waukesha County project sites for fresh concrete testing, cylinder fabrication, aggregate sampling, Proctor testing, nuclear density, soil classification, and corrosivity evaluation — all performed to current ASTM standards under a documented laboratory quality system, with clear, timely reporting built for specification compliance.
Glacially derived soils common to southeastern Wisconsin frequently include moisture-sensitive silts and lean clays that respond poorly to compaction when wet or frozen, making density verification a critical step on nearly every grading or foundation contract in Waukesha County. Wisconsin's freeze-thaw exposure also places concrete work under real durability pressure, and cold-weather placement requirements can affect mix acceptance criteria on project sites from early fall through late spring.
FAQ · Waukesha County
Wisconsin winters are long — how does cold weather affect when and how you perform concrete field testing?
Cold weather changes what our technicians observe and record during fresh concrete testing. When ambient or concrete temperatures approach thresholds defined in ACI 306R, we verify concrete temperature per ASTM C1064 and document conditions that affect cylinder curing. Cylinders must be protected from freezing during the initial 24-hour curing period; failure to do so invalidates the break. Our reports capture all temperature and field-curing conditions so your cold-weather plan holds up to review.
Our Waukesha County site has highly variable fill — some areas pass density and others fail repeatedly. What testing approach helps diagnose that?
Inconsistent density results on glacially deposited or imported fill often reflect variable moisture content, lift thickness, or material changes rather than equipment effort alone. We perform in-place density testing per ASTM D6938 (nuclear gauge) or ASTM D1556 and compare results to a laboratory Proctor (ASTM D698 or D1557) tied to the specific material being placed. When failures cluster, reviewing proctor curves against actual gradation and moisture data helps identify the root cause.
Waukesha County projects often involve engineered fill over expansive or compressible native soils. What soil classification work do you provide to support geotechnical recommendations?
We perform soil classification testing including grain size analysis per ASTM D6913, Atterberg limits per ASTM D4318, and moisture-density relationships per ASTM D698 or D1557. These tests define whether a soil is suitable for structural fill and at what moisture range it can be compacted reliably. Results feed directly into bearing and settlement analyses and give the engineer of record documented data rather than field estimates.
How fast can a technician be on site in Waukesha County?
Waukesha County 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 Waukesha County, WI?
Field work in Waukesha County is dispatched through the Chicago, IL regional hub, about 84 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Waukesha County projects.
Are the technicians you send to Waukesha 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 Wisconsin agencies or owners require state-specific certifications, those are confirmed in the proposal.
