Scope
What we test in Forsyth 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 Forsyth County
Forsyth County is in the middle of a sustained construction cycle — commercial development along major corridors, institutional projects anchored by healthcare and education, and residential growth pushing into the Piedmont fringe. The region's red clay soils, typical of the Carolina Piedmont, can be slow to drain and sensitive to moisture variation, which makes proper compaction verification and soil classification critical before concrete is ever placed. Temperature swings between winter cold snaps and humid summer heat also put real demands on concrete mix performance and curing windows. Our firm dispatches certified field technicians from our Charlotte regional hub to serve Forsyth County project sites, covering fresh concrete testing, cylinder breaks, aggregate evaluation, Proctor and nuclear density, soil classification, and corrosivity testing — all performed to ASTM standards under a documented quality system and reported in a format prepared for third-party review.
Piedmont soils in the Forsyth County area are commonly residual soils derived from weathered metamorphic and igneous rock, exhibiting significant plasticity variation that warrants careful classification per ASTM D2487 and moisture-density relationships per ASTM D1557 or D698 before fill placement. North Carolina's humid subtropical climate means that summer heat and afternoon thunderstorms can compress usable concrete placement windows, making timely fresh concrete testing — including temperature, slump, and air content per ASTM C143, C1064, and C231 — especially important on exposed or large-slab pours.
FAQ · Forsyth County
Forsyth County projects often involve heavy clay fill. Which compaction standard applies, and how do you establish the right moisture-density curve for that material?
Piedmont red clays commonly classify as CL or CH under ASTM D2487. The appropriate compaction standard — either Standard Proctor (ASTM D698) or Modified Proctor (ASTM D1557) — is set by the project specification or geotechnical report. Our technicians run the lab curve on representative samples and then field-verify density using a nuclear gauge per ASTM D6938, comparing results to the specified percent compaction.
We're pouring slabs in July in Winston-Salem. What concrete testing is required and how does summer heat affect the process?
Fresh concrete testing per ACI 301 and ASTM standards includes temperature (C1064), slump or slump flow (C143/C1611), air content (C231), and unit weight (C138). In Forsyth County summers, concrete temperatures can approach or exceed the 95°F limit under ACI 305R hot-weather guidelines. Our technicians document temperature at point of discharge and flag mixes that approach specification thresholds, giving your team defensible documentation if mix performance is questioned.
How far out is your nearest hub, and what lead time should I build into my schedule for materials testing coverage in Forsyth County?
Forsyth County is covered through our Charlotte, NC regional hub, approximately 69 miles from the Winston-Salem area. We recommend scheduling testing requests at least 48 to 72 hours in advance for routine concrete and compaction visits. For continuous or high-frequency testing phases — such as foundation pours or earthwork with daily density requirements — we can establish a project-specific schedule to maintain reliable coverage.
How fast can a technician be on site in Forsyth County?
Forsyth 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 Forsyth County, NC?
Field work in Forsyth County is dispatched through the Charlotte, NC regional hub, about 69 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Forsyth County projects.
Are the technicians you send to Forsyth 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.
