Scope
What we test in Hillsborough 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 Hillsborough County
Hillsborough County's construction environment presents a specific set of challenges that make rigorous materials testing essential rather than optional. The region's sandy, often loose surface soils and high groundwater table demand careful compaction verification before foundations, slabs, or roadway subgrades are placed. Florida's heat and humidity accelerate cement hydration and affect workability windows, meaning fresh concrete must be tested promptly in the field to capture accurate slump, air content, and temperature data. Active commercial development, residential growth, and infrastructure work across Tampa and surrounding unincorporated areas all generate demand for defensible, specification-compliant test data. Our Tampa regional hub dispatches ACI- and NICET-certified field technicians throughout Hillsborough County to perform ASTM-compliant concrete, aggregate, and soil testing, with results documented under a laboratory quality system and reported in a format prepared for third-party review.
Hillsborough County soils frequently include fine sands and organics that require close attention during Proctor testing and compaction verification, as density targets can vary significantly with minor changes in moisture and fines content. Florida's warm, humid climate shortens the usable testing window for fresh concrete, making prompt field sampling practices under ASTM C172 particularly important on local projects.
FAQ · Hillsborough County
How does Florida's heat affect concrete cylinder curing, and how do you handle it on Hillsborough County job sites?
High ambient temperatures accelerate early hydration, which can artificially inflate early-break strengths while compromising 28-day results if cylinders are not protected. Field technicians follow ASTM C31 initial curing requirements — maintaining cylinders between 60°F and 80°F for the first 24 hours. On Tampa-area sites, that typically means insulated curing boxes or shaded storage away from direct sun, particularly during summer months.
Hillsborough County has a long rainy season. Can you still perform nuclear density testing during or after heavy rainfall?
Nuclear gauge readings under ASTM D6938 can be compromised when surface soils are saturated, because excess moisture skews density and moisture readings. Technicians assess site conditions before testing and, when standing water or surface saturation is present, will document conditions and coordinate with the project engineer on timing. Testing lift material that has drained and been re-worked is generally the correct approach.
What soil classification methods do you use, and why does it matter for Hillsborough County projects?
Technicians perform sieve analysis per ASTM D6913 and Atterberg limits per ASTM D4318, supporting USCS classification under ASTM D2487. In Hillsborough County, soils commonly range from clean sands to silty or organic-bearing materials. Proper classification determines which Proctor method applies — ASTM D698 or D1557 — and informs the compaction specification, which directly affects foundation and pavement subgrade acceptance decisions.
How fast can a technician be on site in Hillsborough County?
Hillsborough County work is dispatched through our Tampa, FL 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 Hillsborough County, FL?
Field work in Hillsborough County is dispatched through the Tampa, FL regional hub. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Hillsborough County projects.
Are the technicians you send to Hillsborough 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 Florida agencies or owners require state-specific certifications, those are confirmed in the proposal.
