Scope
What we test in Jacksonville
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 Jacksonville
Jacksonville's construction environment presents a specific set of conditions that demand disciplined materials testing from the first earthwork lift to the final concrete placement. The region's expansive coastal plain soils — ranging from loose sands to organics-laden profiles — require careful characterization before foundations and embankments are built. Florida's heat and humidity accelerate concrete setting times, compress workability windows, and affect moisture-density relationships in ways that make field testing precision, not a formality, but a project safeguard. Our firm dispatches certified ACI and NICET field technicians to Jacksonville-area projects through our Orlando regional hub, covering fresh concrete testing, cylinder fabrication and compression breaks, aggregate gradation and quality testing, Proctor compaction curves, nuclear and sand-cone density, soil classification, and soil corrosivity analysis. Testing follows applicable ASTM designations, technicians operate under a documented quality system, and reports are prepared for third-party review. We handle scheduled programs and project-based assignments for contractors, developers, and engineers across the metro and surrounding counties.
Jacksonville's subsurface frequently includes fine sands and moisture-sensitive soils that can complicate compaction control and bearing capacity — conditions that make ASTM D698/D1557 Proctor baselines and consistent in-place density verification essential rather than optional on earthwork-intensive projects. Florida's climate means fresh concrete testing windows can be short during summer months, reinforcing the importance of timely field testing at point of discharge in accordance with ASTM C172 sampling requirements.
FAQ · Jacksonville
What soil classification methods do you use, and why does it matter for Jacksonville projects?
Technicians classify soils using ASTM D2487 (USCS) and, where specified, AASHTO M 145. Jacksonville's coastal plain soils frequently include fine sands, silts, and organic material that require accurate classification before fill acceptance decisions or foundation design recommendations can be made. Misclassifying a marginal soil can affect both compaction performance and long-term bearing behavior, so classification is treated as a foundational step, not a routine checkbox.
How do Florida's summer temperatures affect your concrete testing procedures on Jacksonville job sites?
High ambient temperatures accelerate cement hydration, reducing slump retention and compressing the placement window. Technicians record concrete temperature at the point of discharge per ASTM C1064 alongside slump (ASTM C143), air content (ASTM C231), and unit weight (ASTM C138). These readings document whether fresh concrete meets specification tolerances before cylinder sets are cast per ASTM C31, which also prescribes initial curing temperature ranges that must be maintained in hot-weather conditions.
How long does it take to get compressive strength results after cylinders are cast on a Jacksonville project?
Standard break schedules are 7-day and 28-day per project specification, with cylinders cured and tested in accordance with ASTM C39. Some specifications also require 3-day breaks for early-strength mixes or post-tensioned work. Once a cylinder is tested, the result and associated batch data are compiled into a written report. Turnaround from break to report delivery depends on lab queue and report review, but we communicate expected timelines at project setup.
How fast can a technician be on site in Jacksonville?
Jacksonville 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 Jacksonville, FL?
Field work in Jacksonville is dispatched through the Orlando, FL regional hub, about 125 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Jacksonville projects.
Are the technicians you send to Jacksonville 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.
