Scope
What we test in Greenville 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 Greenville County
Greenville County sits at the base of the Blue Ridge escarpment, where the Piedmont's red clay soils, weathered gneiss, and variable fill conditions demand rigorous geotechnical and materials verification before and throughout construction. Rapid commercial and industrial growth along the I-85 corridor — distribution facilities, manufacturing plants, mixed-use developments, and institutional projects — means owners and engineers are managing compressed schedules alongside demanding structural and earthwork specifications. Construction Materials Testing from our firm gives project teams in Greenville County field and laboratory data they can defend: fresh concrete testing and cylinder breaks, aggregate gradation and quality, Proctor compaction curves, nuclear density gauge readings, soil classification, and soil corrosivity analysis. Certified ACI and NICET field technicians are dispatched from our Charlotte regional hub, and every test is executed to current ASTM standards under a documented quality system. Reports are clear, prompt, and formatted for submittal to engineers and building officials.
The Piedmont soils common to Greenville County — including residual red clays and weathered rock profiles — can exhibit significant variability in compaction behavior and plasticity, making Proctor curve selection and in-place density verification especially important for foundations, pavements, and structural fill. Hot, humid summers in the South Carolina Upstate also affect fresh concrete workability and set time, which makes timely field testing during placement critical to documenting specification compliance.
FAQ · Greenville County
Greenville County's Piedmont soils are notoriously variable. How do you determine which Proctor curve applies to soil on our site?
The technician collects a representative bulk sample and runs a standard or modified Proctor compaction test — ASTM D698 or ASTM D1557, respectively — based on your project specification's compaction energy requirement. Because Piedmont residual soils can shift in plasticity across short distances, separate Proctor curves may be warranted for distinct soil types encountered during earthwork. The governing curve is referenced on every nuclear or sand-cone density field report.
How does summer heat in the Upstate affect concrete cylinder breaks, and how do you handle it in the field?
High ambient temperatures accelerate cement hydration, raising fresh concrete temperatures and potentially reducing long-term strength if water is added at the truck. Technicians record concrete temperature per ASTM C1064 at the point of discharge, document slump per ASTM C143, and note any observed wash-water additions. Cylinders are initially cured in insulated field boxes to buffer temperature swings before transport to the laboratory, consistent with ASTM C31 initial-cure requirements.
What soil classification tests do you perform, and how does the result affect our subgrade design decisions?
We run grain-size analysis per ASTM D6913 or ASTM D422, Atterberg limits per ASTM D4318, and USCS classification per ASTM D2487. For projects referencing AASHTO classification, ASTM D3282 applies. Results define whether a subgrade layer is expansive, frost-susceptible, or suitable for structural fill, directly informing subgrade stabilization decisions, select fill import requirements, and pavement section design that engineers specify on Greenville County projects.
How fast can a technician be on site in Greenville County?
Greenville 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 Greenville County, SC?
Field work in Greenville County is dispatched through the Charlotte, NC regional hub, about 92 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Greenville County projects.
Are the technicians you send to Greenville 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 South Carolina agencies or owners require state-specific certifications, those are confirmed in the proposal.
