Scope

What we test in Mecklenburg 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.

ASTM D698ASTM D1557ASTM D558ASTM D4718ASTM D6938

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.

ASTM G51ASTM G57ASTM G187

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 Mecklenburg County

Mecklenburg County is in the middle of one of the fastest-growing construction markets in the Southeast. Multifamily towers, logistics facilities, road widenings, and mixed-use developments are all competing for the same subgrade, the same concrete pours, and the same inspection resources. The Piedmont's residual soils — weathered from crystalline rock — vary significantly in bearing capacity and behavior across short distances, and North Carolina's warm, humid summers compress the window for quality concrete placement without pushing the limits of ACI 305 hot-weather guidelines. Errors in compaction, gradation, or cylinder curing that might go undetected elsewhere tend to surface later as expensive problems here. We dispatch certified field technicians from our Charlotte-area regional hub to provide ASTM-compliant testing of concrete, aggregate, and soil — fresh concrete properties, compressive strength cylinders, Proctor compaction, nuclear density, gradation, and soil classification — under a documented quality system, with reporting built to hold up in the field and in front of a project engineer.

Piedmont residual soils in Mecklenburg County frequently exhibit abrupt transitions in plasticity and bearing capacity that make soil classification and compaction verification critical at each lift, not just at subgrade. Summer heat and humidity also require concrete technicians to monitor fresh concrete temperatures and slump carefully in accordance with ACI 305R to protect early strength gain.

FAQ · Mecklenburg County

Mecklenburg County building inspections are already busy — how does your testing fit into the project inspection schedule without causing delays?

We coordinate testing visits around your pour schedule and grading operations, not the other way around. For concrete, we align with ASTM C172 sampling windows and ACI 301 frequency requirements so cylinder sets and fresh concrete data are captured without holding up placement. Compaction testing is sequenced by lift, keeping grading crews moving. Reports are delivered promptly so punch items don't linger.

Charlotte sees high summer temperatures — what does that mean for concrete cylinder curing and early-strength results on my project?

ACI 305R defines hot-weather concreting conditions beginning at 90°F ambient or when evaporation rates are elevated. Technicians monitor fresh concrete temperature per ASTM C1064 at the point of discharge. Initial curing of cylinders follows ASTM C31, which requires field-curing conditions be maintained within a specified temperature range before transport to the laboratory, protecting the integrity of 28-day break data.

The Piedmont soils under my site look like weathered rock in some areas and red clay in others — can you classify and test both in the same mobilization?

Yes. Technicians collect representative samples for classification under ASTM D2487 (Unified Soil Classification System) and moisture-density relationship testing under ASTM D698 or D1557, depending on your compaction specification. Highly variable residual soils often require multiple Proctor curves across a single site; we flag those conditions in the report so your geotechnical engineer can make informed decisions on fill acceptance criteria.

How fast can a technician be on site in Mecklenburg County?

Mecklenburg County work is dispatched through our Charlotte, NC 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 Mecklenburg County, NC?

Field work in Mecklenburg County is dispatched through the Charlotte, NC regional hub. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Mecklenburg County projects.

Are the technicians you send to Mecklenburg 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 North Carolina agencies or owners require state-specific certifications, those are confirmed in the proposal.
