Scope
What we test in Hinds 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 Hinds County
Hinds County sits in the heart of Mississippi's Jackson metro, where active commercial development, highway infrastructure, and public institutional construction run against the realities of expansive, high-plasticity clays common to the region's soil profile. Those soils shift with seasonal moisture changes — wet winters and hot, dry summers drive swell-shrink cycles that make subgrade preparation and compaction verification genuinely consequential, not procedural. Concrete placed during Mississippi's humid summer months demands careful attention to water-cement ratio, air content, and set time to meet structural specifications. Our firm provides ASTM-compliant field and laboratory testing of concrete, soil, and aggregate for Hinds County projects, dispatched through our regional hub network. Certified ACI and NICET technicians handle fresh concrete testing, cylinder breaks, Proctor compaction, nuclear density, aggregate gradation, soil classification, and soil corrosivity — all under a documented quality system — with defensible reports prepared for third-party review.
Hinds County's native soils frequently include high-plasticity clays that respond significantly to Mississippi's pronounced wet and dry seasonal cycles, making moisture-density relationship testing and field compaction verification critical steps before placing any structural fill or pavement subbase. Concrete construction in the region must account for extended periods of high heat and humidity that can accelerate hydration and affect slump, air content, and strength development if not monitored in the field per applicable ASTM procedures.
FAQ · Hinds County
Mississippi's clay soils are notorious for shrink-swell behavior — what testing do you perform to characterize subgrade conditions before we build on them?
We perform Atterberg limits testing (ASTM D4318) to establish plasticity index, grain-size analysis (ASTM D6913 / D7928), and USCS or AASHTO soil classification to document shrink-swell potential. A standard Proctor (ASTM D698) or modified Proctor (ASTM D1557) establishes the moisture-density relationship your compaction specification references. This baseline data directly informs subgrade treatment decisions and earthwork acceptance criteria.
Summer heat in the Jackson area can be brutal — how does that affect fresh concrete testing, and what do your technicians check for?
High ambient temperatures accelerate cement hydration, reducing workability and increasing the risk of early stiffening and cracking. Per ASTM C1064, our technicians measure concrete temperature at the point of discharge. They also perform slump (ASTM C143), air content (ASTM C231), and unit weight (ASTM C138) tests, then cast cylinders per ASTM C31. Elevated concrete temperatures are flagged in the field report so the engineer of record can evaluate compliance with project specifications.
We're working on a federally funded highway project in Hinds County — will your testing documentation satisfy MDOT and federal reporting requirements?
Our technicians follow ASTM test methods standard to MDOT construction specifications, and our laboratory operates under a documented quality system with controlled chain of custody for all specimens. Field reports identify the test method, result, specification limit, and pass/fail status. We recommend confirming specific submittal format requirements with the project engineer, as MDOT and FHWA-funded projects may require particular documentation templates or hold-point notifications.
How fast can a technician be on site in Hinds County?
Hinds 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 Hinds County, MS?
Field work in Hinds County is dispatched through the Nashville, TN regional hub, about 330 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Hinds County projects.
Are the technicians you send to Hinds 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.
