Scope
What we test in Macon
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.

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 Macon
Macon sits at the geological transition between Georgia's Piedmont and Coastal Plain, where red clay soils of varying plasticity give way to sandy, residuum-influenced profiles as you move south through Bibb County. That variability matters on every grading, foundation, and pavement project in the region — a fill section that compacts easily in one area of a site may behave entirely differently a hundred feet away. Meanwhile, Georgia's warm, humid summers create real challenges for concrete work: elevated ambient and mix temperatures can accelerate slump loss and affect early strength gain in ways that make systematic field testing more than a formality. Our technicians, dispatched from the Atlanta regional hub, deliver ASTM-compliant field and laboratory testing for concrete, soil, and aggregate on Macon-area projects. Results are documented under a structured quality system and reported in formats your engineer of record, owner, and Georgia DOT project manager can act on with confidence.
Central Georgia's mix of expansive Piedmont clays and transitional Coastal Plain soils means soil classification and moisture-density relationships can shift considerably across a single project site, making representative Proctor sampling (ASTM D698 / D1557) and careful density verification essential. Summer heat and humidity in Macon also make concrete placement temperature monitoring and timely cylinder curing a practical concern on any structural pour.
FAQ · Macon
How do you handle Proctor sampling when soils change significantly across a Macon project site?
When visual classification or in-place testing indicates a material change — different plasticity, color, or gradation — a separate moisture-density relationship curve should be established for that material. ASTM D698 (Standard Proctor) or D1557 (Modified Proctor) testing is performed on representative samples from each distinct soil type so field density results are compared to the correct baseline, not a curve developed from a different material.
What concrete temperature limits should I be working around during a Macon summer pour?
ACI 305R (Hot Weather Concreting) provides the practical guidance here. Concrete delivered above 95°F is a quality concern; ACI 305R recommends keeping fresh concrete temperature at or below 95°F at point of discharge, with many project specifications tightening that to 90°F. Our technicians measure and record concrete temperature at every sampling event per ASTM C1064, and out-of-limit readings are documented and reported promptly so the contractor and engineer can respond.
Can your lab run aggregate gradation and quality testing for a Macon road or parking lot project?
Yes. Laboratory aggregate testing includes sieve analysis per ASTM C136 for fine aggregate and ASTM C136/D6913 for coarse and mixed gradations, along with quality indices such as Los Angeles abrasion (ASTM C131/C535) and material finer than the No. 200 sieve (ASTM C117). Results are compared against the applicable project specification or GDOT Standard Specifications and reported with the raw data and calculated values.
How fast can a technician be on site in Macon?
Macon 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 Macon, GA?
Field work in Macon is dispatched through the Atlanta, GA regional hub, about 77 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Macon projects.
Are the technicians you send to Macon 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.
