Scope
What we test in Mobile
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 Mobile
Mobile sits at the confluence of the Mobile River and Mobile Bay, where high annual rainfall, a humid subtropical climate, and coastal proximity create conditions that test construction materials year-round. Expansive and compressible soils are common across much of the region, and concrete placed during Alabama's long, hot summers demands careful attention to fresh concrete temperature, water-cement ratio, and set time if design strength is to be achieved. Contractors and engineers working in Mobile — whether on port infrastructure, industrial facilities, commercial development, or roadway and bridge work — need materials testing prepared for third-party review and project specifications. Our certified field technicians cover the Mobile market on a scheduled and project-based basis, performing ASTM-compliant testing of concrete, soil, and aggregate in the field and in a laboratory operating under a documented quality system. Reports are structured for defensibility, so data is usable when it matters most.
Much of coastal Alabama's near-surface soils include fine-grained, moisture-sensitive clays that can vary in bearing capacity and compressibility across a single site, making thorough Proctor testing and field density verification important on virtually every earthwork project. Mobile's high annual precipitation and warm temperatures also create an extended construction season with elevated ambient and concrete mix temperatures, conditions that directly influence concrete curing procedures and compressive strength development.
FAQ · Mobile
Mobile receives heavy rainfall throughout the year — how does that affect soil compaction testing on my project?
Frequent rainfall in the Mobile area can push in-place moisture content above the optimum moisture content established during Proctor testing (ASTM D698 or D1557), causing fill to fail density requirements even when it appears stable. Our technicians verify field density and moisture using nuclear gauge methods (ASTM D6938) and document conditions at the time of testing, giving you a clear record for addressing compaction failures before they become structural problems.
How does summer heat in Mobile affect concrete testing, and what does your technician do about it?
ACI 305R identifies concrete temperatures above 90°F as a hot-weather concern. During Alabama summers, our technicians measure and document fresh concrete temperature, slump, air content, and unit weight per ASTM C172 (sampling) and the relevant ASTM C143, C231, and C138 methods at the point of discharge. Cylinder sets are cast, cured, and broken per ASTM C31 and C39, and elevated placement temperatures are flagged in the report for the engineer of record.
The clay soils on my Mobile site are being classified by your lab — what test methods are used, and how does that affect my project?
Soil classification for project soils typically uses the Unified Soil Classification System, supported by ASTM D4318 (Atterberg limits), ASTM D422 or D7928 (particle size distribution), and ASTM D2487 (classification). For Mobile's fine-grained coastal plain soils, classification results directly inform compaction specifications, subgrade treatment decisions, and whether a moisture-conditioning or stabilization step is warranted before structural fill placement.
How fast can a technician be on site in Mobile?
Mobile work is dispatched through our Atlanta, GA 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 Mobile, AL?
Field work in Mobile is dispatched through the Atlanta, GA regional hub, about 300 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Mobile projects.
Are the technicians you send to Mobile 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 Alabama agencies or owners require state-specific certifications, those are confirmed in the proposal.
