Scope
What we test in Overland Park
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 Overland Park
Overland Park sits on the edge of the Kansas City metro, where a strong pipeline of commercial, mixed-use, and suburban development keeps construction activity consistent year-round. The region's glacially influenced soils — frequently clay-rich and prone to volume change with moisture — demand rigorous compaction verification and soil classification before any structure goes in the ground. Kansas winters also compress concrete placement windows, making fresh concrete testing for temperature, slump, and air content critical to avoid cold-weather placements that later fail cylinder breaks. Our field technicians, holding ACI and NICET certifications, dispatch from our Kansas City, MO regional hub roughly ten miles away to cover scheduled and project-based assignments across Overland Park. From Proctor testing and nuclear density gauge readings during earthwork through aggregate gradation and final cylinder breaks at project closeout, every service follows ASTM-referenced procedures and is documented under a formal quality system that produces defensible, reportable data your project team and authority having jurisdiction can rely on.
The greater Kansas City region commonly encounters expansive clay subgrades that respond significantly to seasonal moisture variation, making accurate moisture-density relationship testing per ASTM D698 or D1557 essential before structural fills are placed. Winter construction in the metro — with temperatures routinely dropping below 40°F from November through March — requires close attention to concrete temperature limits per ACI 306 to protect fresh placements from early-age freezing.
FAQ · Overland Park
What soil classification testing is typically needed for commercial grading projects in Overland Park?
Most commercial grading specifications require Unified Soil Classification System identification per ASTM D2487, which includes grain-size analysis (ASTM D6913), Atterberg limits (ASTM D4318), and moisture-density relationships (ASTM D698 or D1557). In this region's clay-dominant subgrades, plasticity index results from Atterberg limits testing are especially important for determining whether native soils are suitable for use as structural fill.
How do cold Kansas winters affect your concrete testing schedule and what accommodations do you make?
Below 40°F ambient or concrete temperatures, ACI 306 cold-weather requirements apply. Technicians record concrete temperature per ASTM C1064 at the point of discharge and document whether the mix meets specification minimums. If temperature is out of range, that is noted in the field report immediately so the contractor and engineer can act before placement continues. Scheduling through our Kansas City hub accounts for weather-driven sequencing changes.
My Overland Park project has a geotechnical recommendation for moisture-conditioning subgrade. How does your testing support that process?
We perform in-place density and moisture testing using a nuclear gauge per ASTM D6938, comparing field results against the laboratory-established moisture-density curve. This lets the earthwork crew and geotechnical engineer see whether the subgrade is within the specified moisture window before compaction and whether target density has been achieved, reducing the risk of future settlement under expansive clay conditions common to this region.
How fast can a technician be on site in Overland Park?
Overland Park 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 Overland Park, KS?
Field work in Overland Park is dispatched through the Kansas City, MO regional hub, about 10 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Overland Park projects.
Are the technicians you send to Overland Park 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.
