Scope
What we test in DeKalb 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 DeKalb County
DeKalb County sits at the intersection of metro Atlanta's sustained development pressure and a geologically varied landscape that demands disciplined materials testing on every project. From dense infill construction near the Perimeter to mixed-use development along major corridors and public infrastructure work throughout the county, the ground conditions here — ranging from Piedmont residual soils to saprolite and variable fill — require careful attention to compaction verification, soil classification, and bearing capacity before a slab, pavement, or structure is trusted to perform. Georgia's humid subtropical climate also means concrete placement windows can be compressed by summer heat and occasional cold fronts, making fresh concrete testing and proper cylinder curing practices consequential, not routine. Dispatched from an Atlanta regional hub approximately nine miles away, our ACI- and NICET-certified field technicians deliver ASTM-compliant testing of concrete, aggregate, and soil under a documented quality system — producing defensible, well-documented reports that hold up with owners, engineers, and the county.
Piedmont residual soils and saprolite profiles common to the DeKalb County area can exhibit significant variability in moisture-density relationships and bearing capacity, making Proctor correlation and careful nuclear density gauge calibration important steps on any earthwork program. Georgia's hot, humid summers compress workable concrete placement windows and elevate evaporation rates, reinforcing the value of consistent fresh concrete testing — including temperature, slump, air content, and unit weight — on every placement.
FAQ · DeKalb County
DeKalb County soils vary a lot across a single site — how do you handle that variability in your compaction testing program?
When soil types change across a site, the moisture-density relationship can shift, and a single Proctor curve may not apply universally. Our technicians verify whether existing Proctor data is representative of the material being placed, and when it is not, we recommend a new ASTM D698 or D1557 curve for that material. Nuclear density gauge readings are then referenced to the applicable curve, keeping your compaction documentation defensible.
How does Georgia's summer heat affect concrete cylinder testing requirements on my DeKalb County project?
High ambient and concrete temperatures during Georgia summers can accelerate hydration and affect early strength gain, making proper initial curing of ASTM C31 field-cured cylinders critical. Our technicians record concrete temperature at the time of casting, verify initial curing conditions meet ASTM C31 requirements, and flag temperature exceedances in field reports. This documentation supports mix evaluation and protects you if early-strength results are questioned.
What soil classification information do you provide, and why does it matter for DeKalb County projects?
We perform ASTM D2487 Unified Soil Classification System testing, which includes grain-size analysis (ASTM D6913 or D422) and Atterberg limits (ASTM D4318). In DeKalb County, where Piedmont residual soils and variable fill are common, accurate classification informs compaction specifications, shrink-swell potential assessments, and subgrade treatment decisions — information that engineers and contractors need before earthwork or pavement subgrade preparation begins.
How fast can a technician be on site in DeKalb County?
DeKalb County work is dispatched through our Atlanta, GA 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 DeKalb County, GA?
Field work in DeKalb County is dispatched through the Atlanta, GA regional hub, about 9 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large DeKalb County projects.
Are the technicians you send to DeKalb 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.
