Scope
What we test in Rankin 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 Rankin County
Rankin County is one of Mississippi's fastest-growing counties, with residential subdivisions, commercial corridors, and infrastructure projects advancing steadily across Brandon, Flowood, and Pearl. Construction here means working with the Gulf Coastal Plain's variable clay-bearing soils, managing concrete placement through hot, humid summers where heat and humidity can accelerate set times and complicate consolidation, and meeting the documentation demands of county, MDOT, and municipal reviewers. Corners cut on materials testing become costly when subgrade fails, cylinders fall short, or compaction records can't withstand a quality audit. Our certified technicians — holding ACI and NICET credentials — provide ASTM-compliant field and laboratory testing for concrete, aggregate, and soil on scheduled or project-based coverage dispatched to Rankin County. Every result is recorded under a documented quality system and delivered in reports built to support owner review, engineer decisions, and agency submittals without ambiguity.
Rankin County's soils commonly include expansive clays and silty clay mixtures characteristic of the Gulf Coastal Plain, making Proctor compaction baselines and field density verification particularly consequential for slab-on-grade and roadway subgrade work. Mississippi's extended warm season — with summer ambient temperatures regularly exceeding 90°F — increases the urgency of timely fresh concrete testing to monitor slump, air content, and temperature in accordance with ACI 305R hot-weather concreting guidance.
FAQ · Rankin County
How do Mississippi's clay soils affect the soil testing I need to specify for my Rankin County project?
Expansive, high-plasticity clays common to this region require careful classification per ASTM D2487 and moisture-density relationship testing per ASTM D698 or D1557 before compaction operations begin. Without an accurate Proctor curve established for your specific borrow or in-situ material, field density targets lack a valid baseline, which creates liability exposure on slab, pavement, and utility corridor work.
What concrete testing is typically required for commercial slab-on-grade work in Rankin County?
Most commercial projects here require fresh concrete testing per ASTM C172 (sampling), C143 (slump), C231 (air content), and C1064 (temperature), followed by cylinder fabrication per ASTM C31 and compressive strength breaks at specified ages per ASTM C39. Project specifications and the engineer of record define the frequency, but IBC Chapter 17 special inspection requirements also govern threshold testing on certain structural elements.
Summer heat in Rankin County is intense — does that change how or when you schedule concrete testing visits?
Yes. When ambient or concrete temperatures approach or exceed 90°F, ACI 305R guidance becomes directly relevant, and ASTM C1064 temperature limits in the project spec may require pour timing adjustments or ice use. Our technicians record concrete temperature at every visit and flag conditions in the report, giving the contractor and engineer documented evidence of field conditions for mix compliance evaluation.
How fast can a technician be on site in Rankin County?
Rankin County work is dispatched through our Nashville, TN 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 Rankin County, MS?
Field work in Rankin County is dispatched through the Nashville, TN regional hub, about 327 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Rankin County projects.
Are the technicians you send to Rankin 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 Mississippi agencies or owners require state-specific certifications, those are confirmed in the proposal.
