Scope
What we test in Sedgwick 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 Sedgwick County
Sedgwick County sits at the center of one of the most active construction markets on the southern Great Plains, with commercial development, industrial facilities, and infrastructure projects demanding materials that perform under wide seasonal temperature swings and across soils that range from soft alluvial deposits near the Arkansas River corridor to expansive clays capable of significant volume change. Getting concrete placed correctly in July heat or verifying that engineered fill will support a tilt-up warehouse slab is not a detail to leave to chance. Our certified field technicians dispatch from our Kansas City regional hub to serve Sedgwick County contractors, developers, and engineers with ASTM-compliant testing of concrete, aggregate, and soil — fresh concrete sampling and cylinder breaks, Proctor compaction and nuclear density, gradation analysis, soil classification, and corrosivity testing — backed by a laboratory operating under a documented quality system and reporting built to hold up in the field and in the project record.
Sedgwick County soils frequently include expansive and fine-grained clays that require careful classification and compaction control; combined with Kansas's broad seasonal temperature range, concrete mix performance and curing conditions should be monitored closely during both summer heat and cold-weather placements.
FAQ · Sedgwick County
Kansas summers are extremely hot. What concrete testing adjustments matter most for summer placements in Sedgwick County?
High ambient temperatures accelerate hydration and reduce slump retention, making fresh concrete testing time-sensitive. Our technicians measure concrete temperature per ASTM C1064, slump per ASTM C143, and air content per ASTM C231 immediately upon discharge. ACI 305R guidance on hot-weather concreting informs what our technicians document, and any temperature exceedance is flagged in the field report so the project team can act before the load is placed.
How does your firm handle cold-weather concrete placement monitoring during Kansas winters?
When ambient temperatures approach or drop below 40°F, concrete temperature at point of delivery becomes a critical acceptance criterion. Technicians record temperature per ASTM C1064 and note protection and heating methods in the field log, consistent with ACI 306R cold-weather concreting guidance. Cylinder curing conditions are also documented because improper field curing during cold weather is a common source of low break results that do not reflect actual in-place strength.
The soils on our Wichita-area site look like heavy clay. What tests do you run to characterize them for a foundation or pavement subgrade design?
For fine-grained and clayey soils common to portions of Sedgwick County, we perform Atterberg limits per ASTM D4318, particle size analysis per ASTM D6913 and ASTM D7928, and USCS classification per ASTM D2487. Standard or modified Proctor (ASTM D698 or ASTM D1557) establishes the compaction curve. This data set gives your geotechnical engineer or designer the inputs needed for foundation bearing, pavement design, or earthwork specification.
How fast can a technician be on site in Sedgwick County?
Sedgwick County work is dispatched through our Kansas City, MO 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 Sedgwick County, KS?
Field work in Sedgwick County is dispatched through the Kansas City, MO regional hub, about 178 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Sedgwick County projects.
Are the technicians you send to Sedgwick 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 Kansas agencies or owners require state-specific certifications, those are confirmed in the proposal.
