Scope
What we test in Marion 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 Marion County
Marion County sits at the center of Indiana's most active construction market, where infrastructure reinvestment, urban infill, and suburban expansion are generating consistent demand for reliable materials data. Indiana's glacially deposited soils vary considerably across the county — ranging from dense till to softer, more compressible layers — making soil classification, Proctor compaction, and in-place density verification essential steps on virtually every graded site. Concrete work here contends with a continental climate that brings hard freezes from November through March and summer heat that can accelerate slump loss and affect set times, putting a premium on accurate fresh concrete testing at the point of placement. Our certified technicians dispatch to Marion County project sites to perform ASTM-compliant field and laboratory testing of concrete, aggregate, and soil. Results move through a documented quality system and are returned in reports prepared for third-party review — without unnecessary delay.
Indiana's glacial legacy leaves Marion County subgrades that can include fine-grained silts and clays with variable bearing characteristics, making ASTM D698/D1557 Proctor testing and ASTM D6938 nuclear density verification standard practice on earthwork contracts. The region's wide seasonal temperature swings — from sub-freezing winters to humid summers — create real risk windows for concrete placement that field testing under ACI 305R and ACI 306R conditions directly addresses.
FAQ · Marion County
Marion County projects often require special inspection under the IBC — does your materials testing work coordinate with that requirement?
Yes. Materials testing frequently runs alongside IBC Chapter 17 special inspection programs. Concrete cylinder breaks, fresh concrete testing, and compaction testing can be structured to satisfy the continuous or periodic special inspection requirements the Statement of Special Inspections identifies. Our technicians document observations in formats that align with what the Authority Having Jurisdiction and the engineer of record typically expect.
What should I expect for scheduling and lead time for a Marion County project?
Coverage for Marion County is dispatched through our regional hub. We work on scheduled and project-based arrangements; contact us to confirm availability for your pour or earthwork window. We do not guarantee same-day response, so coordinating technician visits at least 24 to 48 hours in advance is strongly recommended to align with your construction schedule.
Cold weather concrete placement happens regularly in Indianapolis winters — how does field testing account for those conditions?
Technicians follow ACI 306R guidelines during cold weather placements. Fresh concrete temperature is measured per ASTM C1064, and results are logged with ambient conditions noted. If concrete temperatures approach specification limits, that data is captured in the field report and flagged. This documentation supports contractor decisions on heating, insulation, or modified curing and protects all parties if questions arise later.
How fast can a technician be on site in Marion County?
Marion 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 Marion County, IN?
Field work in Marion County is dispatched through the Chicago, IL regional hub, about 165 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Marion County projects.
Are the technicians you send to Marion 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 Indiana agencies or owners require state-specific certifications, those are confirmed in the proposal.
