Scope
What we test in Chatham 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 Chatham County
Chatham County sits at sea level along Georgia's Atlantic coast, where tidal wetlands, loose sandy coastal plain soils, and a humid subtropical climate create testing demands that go well beyond a standard inland project. Shallow bearing strata, high water tables, and soils prone to moisture variation mean compaction and classification work require close attention from the first earthwork lift through final subgrade acceptance. Summer heat and humidity accelerate concrete set times, making timely fresh-concrete testing — slump, air content, temperature, and unit weight per ASTM C172 and C143 — critical for mix compliance. Our ACI- and NICET-certified field technicians serve Chatham County on a scheduled and project-based basis, dispatched through our regional hub network to cover concrete cylinder programs, aggregate quality testing, Proctor density, nuclear gauge compaction verification, and soil corrosivity sampling. Every result is documented under a quality system built for defensible reporting — giving contractors, developers, and engineers the data they need to move forward with confidence.
Chatham County's coastal plain soils — often fine sands and silty materials with variable organic content near tidal areas — can complicate achieving and verifying compaction targets, making soil classification (ASTM D2487) and moisture-density relationship testing (ASTM D1557 or D698) especially important early in the project schedule. The region's high annual rainfall and warm temperatures also extend the effective concrete construction season but demand consistent fresh-concrete testing to manage slump and set-time variability across seasonal temperature swings.
FAQ · Chatham County
Chatham County has a lot of fill and tidal-influenced ground. What soil testing do you recommend before we begin earthwork?
For coastal plain and fill sites, we typically recommend Atterberg limits (ASTM D4318), grain size analysis (ASTM D6913/D422), and moisture-density (Proctor) testing per ASTM D698 or D1557 before earthwork begins. These establish classification under ASTM D2487 and set the compaction target your field technician will verify with a nuclear density gauge (ASTM D6938) or sand-cone (ASTM D1556) during construction.
How does high humidity and summer heat in Savannah affect concrete testing requirements on our project?
High ambient temperatures accelerate hydration and can reduce slump rapidly between the truck and the point of placement. ASTM C1064 requires concrete temperature be recorded at every sampling event, and ACI 305R sets upper limits on fresh concrete temperature that your mix design may reference. Capturing temperature, slump (ASTM C143), and air content (ASTM C231) promptly at point of discharge is essential to producing defensible compliance data in Chatham County's summer conditions.
Our project is in a low-lying area near the marsh. Do we need corrosivity testing on the soils before installing utilities or reinforced structures?
Yes, for buried metallic utilities or reinforced-earth structures in areas with organic or tidal-influenced soils, corrosivity testing — including soil resistivity, pH, soluble sulfates, and chloride content — is commonly specified. These results inform cathodic protection design and material selection. We collect samples during site visits and process them through our laboratory operating under a documented quality system, with results delivered in a written report suitable for the design team's review.
How fast can a technician be on site in Chatham County?
Chatham 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 Chatham County, GA?
Field work in Chatham County is dispatched through the Charlotte, NC regional hub, about 218 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Chatham County projects.
Are the technicians you send to Chatham 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 Georgia agencies or owners require state-specific certifications, those are confirmed in the proposal.
