Scope
What we test in Greensboro
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 Greensboro
Greensboro sits at the heart of the Piedmont Triad, a region experiencing sustained industrial, logistics, and mixed-use development that puts consistent demand on sound materials testing. Piedmont soils — often residual clays and weathered saprolite derived from underlying crystalline rock — can vary significantly in bearing capacity and compaction behavior across a single site, making proper classification and density verification essential before any slab, pavement, or foundation is placed. North Carolina's humid subtropical climate also means concrete placement must account for high summer temperatures that accelerate set time and threaten strength development. Our firm dispatches certified field technicians to Greensboro projects through our Raleigh regional hub, providing scheduled and project-based coverage for concrete, aggregate, and soil testing. Every technician holds current ACI or NICET certification, and all laboratory work runs under a documented quality system — giving project owners, contractors, and engineers defensible data and clear reporting at each phase of construction.
Piedmont Triad soils commonly include residual clays and saprolite profiles that require careful Proctor compaction testing (ASTM D698 or D1557) and density verification because moisture-plasticity relationships can shift across short distances on the same site. North Carolina's warm, humid summers call for close attention to concrete fresh-property testing per ASTM C1064 and C143, as elevated ambient temperatures can reduce workability windows and affect compressive strength outcomes.
FAQ · Greensboro
Greensboro summers are hot and humid — does that affect how fresh concrete is tested and accepted on my project?
Yes. ASTM C1064 requires concrete temperature to be measured and recorded at the point of delivery, and ACI 305R sets practical limits on placement temperature in hot weather. When ambient conditions are elevated, slump loss between the truck and the pour can be rapid. Technicians capture temperature, slump (ASTM C143), air content (ASTM C231), and unit weight (ASTM C138) promptly after discharge to give you defensible, time-stamped field records before the mix properties drift.
My Greensboro site has variable Piedmont clay soils. How do you determine which Proctor curve to use for compaction control?
Technicians collect representative samples for laboratory moisture-density relationship testing under ASTM D698 (standard effort) or ASTM D1557 (modified effort), depending on your specification. Because Piedmont residual clays and saprolite can vary in plasticity across a site, separate Proctor curves may be warranted for distinct soil types encountered during grading. Soil classification testing per ASTM D2487 (USCS) or ASTM D3282 (AASHTO) informs which curve governs each test area.
How do you handle scheduling for a Greensboro project when your nearest hub is in Raleigh?
Coverage is dispatched from our Raleigh regional hub, approximately 67 miles from Greensboro. We coordinate scheduled visits — concrete placements, compaction testing windows, or sampling events — in advance with your superintendent or project manager. We do not guarantee same-day response, so building technician attendance into your pour schedule and earthwork inspection plan avoids delays. Contact us with your project timeline so we can establish a coverage arrangement that fits your phasing.
How fast can a technician be on site in Greensboro?
Greensboro work is dispatched through our Raleigh, 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 Greensboro, NC?
Field work in Greensboro is dispatched through the Raleigh, NC regional hub, about 67 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Greensboro projects.
Are the technicians you send to Greensboro 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.
