Scope
What we test in Pulaski 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 Pulaski County
Pulaski County sits at the heart of Arkansas's most active construction market, where Little Rock's ongoing infrastructure investment, commercial development, and institutional building programs keep project schedules tight and agency oversight consistent. The Arkansas River corridor and the region's mix of alluvial bottomland and upland clay soils present real geotechnical variability—conditions that make defensible field and laboratory data a practical necessity, not a formality. Our certified technicians cover Pulaski County projects through scheduled and project-based dispatch, performing ASTM-compliant testing of concrete, aggregate, and soil from first earthwork through structural placement. Fresh concrete testing, cylinder curing and breaks, Proctor compaction curves, nuclear density verification, aggregate gradation, and soil classification are all executed under a documented quality system. Reports are produced to support your submittals, agency reviews, and project records—clear, traceable, and prepared for third-party review.
Pulaski County's lowland and river-adjacent zones commonly include expansive or compressible clay soils that respond poorly to moisture changes, making moisture-density relationship testing and field compaction verification especially consequential for subgrade and fill work. Arkansas's hot, humid summers also accelerate concrete hydration, which makes ASTM C1064 temperature monitoring and proper cylinder handling at the point of placement critical to producing representative strength data.
FAQ · Pulaski County
Pulaski County projects often involve clay-heavy fill. What testing do you run to characterize and monitor that material?
For clay-bearing soils, technicians perform ASTM D698 or D1557 Proctor compaction tests to establish moisture-density relationships, ASTM D4318 for Atterberg limits, and ASTM D2487 for unified soil classification. In the field, compaction is verified by nuclear gauge per ASTM D6938 or by sand cone per ASTM D1556. These results together give your geotechnical engineer and inspector a defensible picture of fill performance.
How do Arkansas Department of Transportation or City of Little Rock project requirements affect the testing program you put together?
Agency requirements dictate test frequencies, accepted methods, and reporting format—and they vary by project type. We align the testing program with the applicable project specification, whether that references ARDOT standard specifications, municipal requirements, or the project's own special provisions. Our technicians document test locations, lot references, and pass/fail thresholds so the data maps directly to the submittal your inspector or agency reviewer expects.
Summer heat in Little Rock can be brutal. How does that affect your concrete testing approach on Pulaski County pours?
High ambient temperatures accelerate cement hydration and can push concrete above the 95°F placement limit recognized in ACI 305. Technicians record fresh concrete temperature per ASTM C1064 at every test set, alongside slump (ASTM C143), air content (ASTM C231), and unit weight (ASTM C138). When temperatures are marginal, those readings provide the documented evidence needed to evaluate compliance or trigger a hold before placement continues.
How fast can a technician be on site in Pulaski County?
Pulaski County work is dispatched through our Dallas, TX 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 Pulaski County, AR?
Field work in Pulaski County is dispatched through the Dallas, TX regional hub, about 293 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Pulaski County projects.
Are the technicians you send to Pulaski 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 Arkansas agencies or owners require state-specific certifications, those are confirmed in the proposal.
