Scope
What we test in Scott 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 Scott County
Scott County sits along the Mississippi River in a region where glacial till, alluvial deposits, and clay-heavy soils vary considerably across project sites. That variability matters: fill placed without proper density verification can settle, and concrete poured in Iowa's temperature swings — from subfreezing winters to humid summer heat — demands field controls that match actual conditions. Developers pushing mixed-use corridors along the Quad Cities metro, contractors building distribution facilities, and engineers specifying infrastructure improvements all carry real liability when materials don't perform. Construction materials testing is how that liability gets managed. Dispatched through our Chicago regional hub and staffed by ACI- and NICET-certified field technicians, our team performs ASTM-compliant concrete, aggregate, and soil testing in Scott County on a scheduled and project-based basis. Results are documented under a quality system built for defensibility — the kind prepared for third-party review, a dispute, or a project closeout package.
Scott County's glacial and alluvial soils can exhibit plasticity and moisture sensitivity that directly affect compaction and subgrade performance, making Proctor moisture-density relationships (ASTM D698 / D1557) and field density verification essential steps rather than formalities. Iowa's seasonal temperature range also requires concrete producers and contractors to account for cold-weather and hot-weather placement procedures, and fresh concrete testing at the point of delivery is the practical check that those conditions are actually being met.
FAQ · Scott County
Our spec requires Proctor testing before earthwork begins — how do we get that scheduled given your Chicago hub location?
Scheduling through our Chicago regional hub typically involves lead-time coordination, so notify us when soil submittals are approved and representative samples are available. Laboratory moisture-density relationships under ASTM D698 (standard effort) or ASTM D1557 (modified effort) are run on submitted material, and results are returned with enough lead time to support your earthwork start. Build sample submission into your pre-construction schedule rather than waiting until grading mobilizes.
Iowa winters can be harsh — what concrete field testing happens when ambient temperatures drop near or below freezing?
When temperatures approach freezing, fresh concrete testing under ASTM C172 (sampling), ASTM C1064 (temperature), ASTM C143 (slump), and ASTM C231 (air content) becomes especially critical because cold conditions affect hydration rate and air-void stability. Our technicians document concrete temperature at point of delivery alongside standard plastic property tests, giving your team and the mix designer the field record needed to evaluate whether cold-weather procedures per ACI 306R are being followed as specified.
Alluvial soils near the Mississippi corridor — do you perform soil classification testing to help us confirm fill suitability before placement?
Yes. Laboratory classification testing includes grain-size analysis (ASTM D6913 for sieve, ASTM D7928 for hydrometer where fines require it) and Atterberg limits (ASTM D4318) to assign USCS or AASHTO classification. For sites near river corridors where alluvial deposits and variable plasticity are common, classification data paired with your Proctor results gives a defensible basis for accepting or rejecting proposed fill material before compaction begins.
How fast can a technician be on site in Scott County?
Scott 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 Scott County, IA?
Field work in Scott County is dispatched through the Chicago, IL regional hub, about 154 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Scott County projects.
Are the technicians you send to Scott 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 Iowa agencies or owners require state-specific certifications, those are confirmed in the proposal.
