Scope
What we test in Winston-Salem
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 Winston-Salem
Winston-Salem sits in the Piedmont Triad, where construction ranges from industrial and logistics facilities along major corridors to mid-rise mixed-use development in the urban core and residential subdivision work spreading into the surrounding foothills. The region's residual Piedmont soils — highly weathered, variable in plasticity and bearing capacity — make systematic geotechnical and compaction verification essential, not optional. Seasonal temperature swings also create real windows and risks for concrete placement: summer heat accelerates set times and affects water-to-cementite ratio control, while late-fall and winter pours require close monitoring for compliance with ACI 305R and ACI 306R guidance. Our firm provides ASTM-compliant field and laboratory testing of concrete, soil, and aggregate, with certified technicians dispatched from our Charlotte regional hub to serve Winston-Salem and the broader Forsyth County area. Every engagement is backed by a documented quality system and delivers clear, defensible test reports your project team, owner, and inspecting authority can rely on.
Piedmont soils in the Winston-Salem area are often deeply weathered metamorphic and igneous residuum, meaning moisture-density relationships and classification results can vary considerably across a single site — thorough Proctor testing and consistent nuclear or sand-cone density verification are practical necessities. North Carolina's warm, humid summers also compress workable concrete placement windows and warrant attention to fresh concrete temperature and slump at point of discharge per ASTM C1064 and ASTM C143.
FAQ · Winston-Salem
How does the scheduling and dispatch process work for Winston-Salem projects covered from Charlotte?
Technician coverage for Winston-Salem is dispatched through our Charlotte, NC regional hub, approximately 69 miles away. Scheduling is project-based and planned in advance; we coordinate with your superintendent or project manager to align field visits with pour schedules, earthwork milestones, and inspection windows. Early scheduling communication helps ensure technician availability, particularly during peak construction seasons when regional demand is high.
What soil classification work do you perform, and why does it matter for Piedmont residual soils?
We classify soils using ASTM D2487 (Unified Soil Classification System) and ASTM D422 for gradation along with Atterberg limits per ASTM D4318. Piedmont residual soils — common throughout the Winston-Salem area — can shift from sandy silt to clayey silt within short distances, affecting fill suitability and compaction specifications. Classification testing gives your geotechnical engineer and contractor the data needed to make informed decisions about subgrade preparation and fill acceptance.
What compaction testing standard applies to NCDOT-influenced or state-funded road and utility work in this area?
Projects with NCDOT involvement or state funding typically reference NCDOT Standard Specifications, which can specify density testing by AASHTO T 99 or T 180 alongside ASTM D698 or D1557 Proctor methods. Our technicians are familiar with both frameworks and can perform density verification using nuclear gauge methods per ASTM D6938, ensuring your compaction documentation aligns with the applicable project specification.
How fast can a technician be on site in Winston-Salem?
Winston-Salem 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 Winston-Salem, NC?
Field work in Winston-Salem 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 Winston-Salem projects.
Are the technicians you send to Winston-Salem 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.
