Scope
What we test in Franklin 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 Franklin County
Franklin County is one of the fastest-growing counties in the Midwest, with active commercial, industrial, and residential construction across Columbus and its surrounding communities. Central Ohio's glacially deposited soils — often silty clays and clayey silts with variable bearing capacity — make ground-up verification of compaction and subgrade conditions a practical necessity, not a formality. Concrete placement across a full Ohio construction season adds another layer of complexity: cold-weather and hot-weather protocols can shift within a single month. Our Columbus regional hub dispatches ACI- and NICET-certified technicians to Franklin County projects for ASTM-compliant field and laboratory testing of concrete, aggregate, and soil. The laboratory operates under a documented quality system. From fresh concrete testing and cylinder breaks to Proctor compaction curves, nuclear density verification, aggregate gradation, soil classification, and corrosivity analysis, every engagement produces defensible, specification-ready reporting that satisfies contractors, engineers, and public-agency reviewers alike.
Central Ohio's glacially deposited fine-grained soils are common across Franklin County, making soil classification and moisture-density relationships critical inputs before and during earthwork. Ohio's climate — with freeze-thaw cycles in late fall and early spring — can affect concrete curing windows and compaction timing, reinforcing the value of timely field verification rather than relying solely on ambient conditions.
FAQ · Franklin County
Franklin County has a lot of fill from older site development. How do you handle compaction testing on suspect or variable fill?
When fill origin or composition is unknown, we establish a site-specific moisture-density relationship using ASTM D698 (Standard Proctor) or ASTM D1557 (Modified Proctor), depending on your specification. Field density is then measured by nuclear gauge per ASTM D6938. If material varies significantly across the site, additional Proctor curves may be warranted — we flag that during the initial testing phase so the project team can plan accordingly.
What soil classification system do your reports use, and will it satisfy Columbus-area plan reviewers?
Our technicians classify soils using the Unified Soil Classification System (USCS) per ASTM D2487, which aligns with what geotechnical engineers of record and municipal plan reviewers in Franklin County routinely reference. Where a project's geotechnical report specifies AASHTO classification instead, we can run ASTM D3282. Reports document the basis of classification so the engineer of record can reconcile findings with design assumptions.
We're placing concrete in October in Columbus. What cold-weather precautions show up in your testing and reporting?
Ohio autumns can push concrete placement into ACI 306 cold-weather territory — defined as when ambient temperature is expected to fall below 40°F during or within 24 hours of placement. Our technicians document air temperature, concrete temperature at point of discharge, and mix consistency per ASTM C172 sampling and ASTM C1064 temperature measurement. Reports note ambient conditions so the concrete producer and contractor have a defensible record if cold-weather mix adjustments were in effect.
How fast can a technician be on site in Franklin County?
Franklin County work is dispatched through our Columbus, OH 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 Franklin County, OH?
Field work in Franklin County is dispatched through the Columbus, OH regional hub. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Franklin County projects.
Are the technicians you send to Franklin 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 Ohio agencies or owners require state-specific certifications, those are confirmed in the proposal.
