Scope

What we test in Mobile 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.

ASTM D698ASTM D1557ASTM D558ASTM D4718ASTM D6938

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.

ASTM G51ASTM G57ASTM G187

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 County

Mobile County sits at the confluence of the Mobile-Tensaw Delta and the Gulf Coast, where high annual rainfall, a humid subtropical climate, and proximity to tidal waterways combine to create construction conditions that demand rigorous materials testing at every phase. Expansive and compressible soils are common across the coastal plain, and concrete placed in summer heat and humidity can reach initial set faster than specifications allow for — both conditions that produce costly failures when testing is neglected or poorly documented. Our firm provides ASTM-compliant field and laboratory testing of concrete, soil, and aggregate for projects across Mobile County, dispatched through our Atlanta regional hub. Certified technicians perform fresh concrete testing and cylinder breaks, Proctor and nuclear density compaction testing, aggregate gradation and quality testing, soil classification, and soil corrosivity analysis. Every engagement runs under a documented quality system, and reports are prepared for third-party review.

Coastal plain soils in the Mobile area frequently include soft, high-plasticity clays and loose sandy fills that require careful compaction verification and classification before and during construction — conditions that make Proctor testing and accurate field density control especially consequential. The region's long, hot, and humid construction season also means concrete placement schedules and mix designs benefit from close coordination with fresh concrete testing to manage slump loss and air content before ASTM C31 cylinder fabrication.

FAQ · Mobile County

Mobile County gets heavy rainfall during construction seasons — how does that affect compaction testing schedules and results?

Rainfall above the optimum moisture content established by ASTM D698 or D1557 Proctor testing will push field moisture above target and drop density readings below specification. When rain delays are followed by rapid drying in summer heat, surface crust can form over soft material and return false passing readings with a nuclear gauge. A technician accounts for these conditions by testing at representative depths and documenting moisture trends across the lift, not just the surface reading.

We are placing a large concrete slab-on-grade during a Mobile summer. What testing intervals and precautions apply?

ACI 305R provides guidance on hot-weather concrete practices, and your specification will typically require fresh concrete testing — slump per ASTM C143, air content per ASTM C231, temperature per ASTM C1064, and unit weight per ASTM C138 — at the point of placement, not the truck. In Mobile summer conditions, concrete temperatures can approach or exceed 90°F at discharge, which accelerates set and can compromise strength; documenting temperature at placement is therefore critical, not optional.

My project specification requires soil classification. What does that testing involve and how is it reported?

Soil classification under ASTM D2487 uses grain-size analysis (ASTM D6913 for coarse fractions, ASTM D7928 for fines) and Atterberg limit testing (ASTM D4318) to assign each sample a Unified Soil Classification System group symbol and name. The laboratory report will include the plasticity index, liquid limit, and gradation curve — information your geotechnical engineer uses to verify that fill material and native subgrade meet specification requirements.

How fast can a technician be on site in Mobile County?

Mobile County 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 County, AL?

Field work in Mobile County 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 County projects.

Are the technicians you send to Mobile 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 Alabama agencies or owners require state-specific certifications, those are confirmed in the proposal.
