Scope
What we test in Orange 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 Orange County
Orange County sits at the center of one of the fastest-growing construction markets in the Southeast. Rapid horizontal development, high-rise mixed-use projects along major corridors, and a steady pipeline of infrastructure improvements all depend on materials that perform — and on documentation that holds up when agencies, owners, and insurers ask questions. Florida's high water table, prevalence of loose sandy soils, and warm, humid climate create real variables in both earthwork compaction and concrete placement that require disciplined, ASTM-compliant testing rather than assumptions. Our Orlando-area dispatch hub places certified technicians on Orange County job sites for scheduled and project-based coverage, handling fresh concrete testing and cylinder breaks, aggregate gradation and quality, Proctor compaction and nuclear density, soil classification, and soil corrosivity — all under a documented quality system. Every report is produced to give engineers, contractors, and developers defensible data they can act on.
Orange County's predominantly sandy, low-plasticity soils can complicate achieving and verifying compaction at required density, making proper Proctor baseline testing and consistent nuclear gauge or sand-cone verification essential throughout earthwork operations. Florida's heat and humidity affect concrete workability and set time, so fresh concrete testing — slump or slump flow, air content, temperature, and unit weight per ASTM C172 and C31 — should be performed promptly after sampling to produce representative cylinders.
FAQ · Orange County
Orange County requires special inspections on my permitted project — does your materials testing satisfy that requirement?
Special inspection programs under IBC Chapter 17 and the Florida Building Code require that inspection and testing be performed by qualified personnel and that results be reported to the authority having jurisdiction. Our technicians hold ACI and NICET certifications and generate structured reports suitable for special inspection submittals. Coordinate your Statement of Special Inspections with your engineer of record to confirm which test methods and frequencies are required for your permit.
How does Florida's rainy season affect scheduling concrete cylinder breaks and compaction tests?
Central Florida's summer rainy pattern can interrupt pour schedules and earthwork windows on short notice. We recommend building flexibility into your testing schedule and notifying our dispatch hub when weather causes a push. Cylinders cast per ASTM C31 must be protected from vibration and temperature extremes during initial cure; field curing conditions in Florida summers warrant close attention to avoid compromising break results.
What Proctor method applies to the sandy fill soils common in Orange County?
For granular, low-plasticity sandy soils typical of Central Florida, the Standard Proctor (ASTM D698) is most commonly specified, though ASTM D1557 (Modified Proctor) applies where higher compaction energy is required by the geotechnical report or project specification. The correct method must match what your geotechnical engineer of record used to establish the density requirement — we test to whichever designation your specification references.
How fast can a technician be on site in Orange County?
Orange County work is dispatched through our Orlando, 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 Orange County, FL?
Field work in Orange County is dispatched through the Orlando, FL regional hub. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Orange County projects.
Are the technicians you send to Orange 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.
