Scope
What we test in Spartanburg 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 Spartanburg County
Spartanburg County is in the middle of a sustained construction cycle — industrial facilities, distribution centers, residential subdivisions, and infrastructure projects are all active across the county. The Piedmont soils that underlie much of the region can include residual clays and weathered rock profiles that respond poorly to moisture changes, making proper subgrade verification and compaction testing essential to long-term pavement and slab performance. Concrete placements in South Carolina's hot, humid summers also demand careful attention to water-cement ratio, air content, and slump at the point of delivery, where temperature and evaporation rates can move quickly against specification limits. Our firm dispatches ACI- and NICET-certified field technicians from a regional hub to provide ASTM-compliant testing of concrete, aggregate, and soil — fresh concrete testing, cylinder breaks, Proctor compaction, nuclear density, gradation, soil classification, and corrosivity — backed by a laboratory operating under a documented quality system and reporting prepared for third-party review.
Piedmont residual soils common to the Spartanburg County area often exhibit variable plasticity and can be sensitive to construction-season rainfall, making moisture-density relationship testing and field compaction verification particularly important on earthwork-heavy projects. Summer concrete placements should account for ambient temperatures and direct sun exposure, as South Carolina's climate can accelerate slump loss and affect cylinder curing conditions.
FAQ · Spartanburg County
How do Spartanburg County's Piedmont soils affect what compaction testing I need?
Residual Piedmont soils — common across the South Carolina Upstate — often contain silty clays and weathered rock fines with moisture sensitivity. Establishing an accurate moisture-density relationship per ASTM D698 or D1557 before earthwork begins is critical, because the optimum moisture content of these soils can shift with borrow source and depth. Field density verification by nuclear gauge (ASTM D6938) then confirms each lift meets the compaction percentage your specification requires.
It gets hot fast on Spartanburg job sites in summer — how does that affect concrete cylinder sampling?
High ambient temperatures accelerate hydration and can push concrete temperatures above the 95°F limit referenced in ACI 305. During fresh concrete testing per ASTM C172, our technicians record concrete temperature alongside slump (ASTM C143), air content (ASTM C231), and unit weight (ASTM C138). Cylinders are cast per ASTM C31, and initial curing in the field must protect specimens from temperature extremes before transport to the laboratory for standard-cured breaks per ASTM C39.
Which South Carolina or local agency standards govern materials testing on projects in Spartanburg County?
Most public infrastructure work references SCDOT standard specifications, which incorporate AASHTO and ASTM test methods for soils, aggregate, and concrete. Private commercial and industrial projects typically run to IBC Chapter 17 special inspection requirements, where the project's statement of special inspections drives the testing program. Our technicians work to the applicable ASTM edition cited in your project specification or agency requirement — confirm the controlling specification with your engineer of record at the preconstruction stage.
How fast can a technician be on site in Spartanburg County?
Spartanburg 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 Spartanburg County, SC?
Field work in Spartanburg County is dispatched through the Charlotte, NC regional hub, about 64 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Spartanburg County projects.
Are the technicians you send to Spartanburg 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.
