Scope
What we test in Hattiesburg
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 Hattiesburg
Hattiesburg sits in the Pine Belt region of south Mississippi, where development pressure from healthcare, education, and logistics sectors keeps construction activity steady. The regional soils — predominantly fine-grained silts and clays common to the coastal plain — are moisture-sensitive and can behave unpredictably under load if not properly evaluated before and during earthwork. Concrete placement in this climate demands attention year-round: summer heat and humidity accelerate slump loss and affect set times, while occasional winter cold fronts require monitoring of fresh concrete temperatures against ACI 306 cold-weather thresholds. Our firm dispatches certified field technicians to Hattiesburg on a scheduled and project-based basis, performing ASTM-compliant testing of concrete, aggregate, and soil from placement through laboratory analysis. The laboratory operates under a documented quality system, and every report is built to hold up in the project record. Coverage is coordinated through our regional hub to serve projects across the Hattiesburg metro and surrounding Forrest and Lamar County areas.
South Mississippi's coastal plain soils frequently include expansive clays and moisture-susceptible fine-grained materials that require careful classification and compaction control — conditions that make Proctor testing and in-place density verification particularly important on grading and subgrade work. The region's warm, humid climate can shorten workable concrete windows, making timely slump, air content, and temperature sampling at the point of placement a practical necessity rather than a formality.
FAQ · Hattiesburg
Our project is in Lamar County, just north of Hattiesburg — does your coverage area reach that far?
Yes. Technician dispatch covers Hattiesburg and the surrounding metro area, including Lamar and Forrest counties, on a scheduled and project-based basis. Coverage is coordinated through our regional hub, so the best approach is to contact us early in your project schedule so mobilization windows can be planned around your earthwork and concrete placement sequences.
South Mississippi summers are brutal — how does extreme heat affect concrete testing on our slab pours?
High ambient temperatures and direct sun exposure accelerate cement hydration, which can reduce slump and shorten the time window before initial set. ACI 305 defines hot-weather concreting conditions and the precautions required. Our technicians record concrete temperature per ASTM C1064 at the point of discharge and document conditions that may affect cylinder curing — information that becomes part of the defensible project record.
We're grading a commercial site with heavy clay soils near Hattiesburg — what compaction testing program makes sense?
Standard practice begins with a Proctor curve — either ASTM D698 (standard effort) or ASTM D1557 (modified effort), depending on your specification — to establish the maximum dry density and optimum moisture content for the material. In-place density is then verified by nuclear gauge per ASTM D6938 or sand cone per ASTM D1556 at frequencies called out in the project geotechnical report or specification.
How fast can a technician be on site in Hattiesburg?
Hattiesburg 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 Hattiesburg, MS?
Field work in Hattiesburg is dispatched through the Atlanta, GA regional hub, about 331 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Hattiesburg projects.
Are the technicians you send to Hattiesburg 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 Mississippi agencies or owners require state-specific certifications, those are confirmed in the proposal.
