Scope
What we test in Fairbanks
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 Fairbanks
Building in Fairbanks demands more from construction materials testing than almost anywhere else in the country. Permafrost, extreme freeze-thaw cycling, and winter temperatures that regularly fall below -40°F create conditions where subgrade behavior, concrete mix performance, and compaction results can diverge sharply from Lower 48 norms. A fill section that tests well in summer can behave entirely differently once seasonal freeze sets in, and concrete placed during shoulder seasons requires verified air content, slump, and strength data to demonstrate specification compliance. Our firm dispatches certified field technicians to Fairbanks project sites to perform ASTM-compliant testing of concrete, aggregate, and soil — fresh concrete evaluation and cylinder breaks, aggregate gradation and quality, Proctor compaction, nuclear density, soil classification, and soil corrosivity. The laboratory operates under a documented quality system, and every report is prepared for third-party review. Coverage is coordinated through our Seattle regional hub on a scheduled and project-based basis.
Interior Alaska soils frequently include frost-susceptible silts and organics that require careful classification and compaction control; ADOT&PF and local agency specifications often impose additional requirements beyond standard ASTM methods. Concrete work in the Fairbanks area is constrained by a short warm season, making timely cold-weather concrete testing and documentation — including temperature monitoring per ACI 306 — a practical necessity on most structural pours.
FAQ · Fairbanks
How do you handle concrete testing when ambient temperatures are below freezing at the pour?
ACI 306R establishes guidance for cold-weather concrete, and our technicians measure and record fresh concrete temperature alongside slump (ASTM C143), air content (ASTM C231 or C173), and unit weight (ASTM C138) at point of placement. Cylinder sets are protected and cured per ASTM C31 cold-weather provisions. These records document that mix temperature and handling met specification limits before cylinders were cast.
Can you perform soil classification testing relevant to permafrost-adjacent or frost-susceptible subgrades?
Yes. Technicians collect samples for laboratory grain-size analysis per ASTM D6913 and Atterberg limits per ASTM D4318, which together support Unified Soil Classification System (ASTM D2487) designation. Identifying frost-susceptible silts and clays — common in the Fairbanks area — early in a project allows the design team to specify appropriate fill, compaction criteria, or subgrade treatment before construction is underway.
What Proctor method applies to my project, and can you run it for Fairbanks subgrade work?
Standard Proctor (ASTM D698) and Modified Proctor (ASTM D1557) differ in compactive effort and produce different maximum dry density and optimum moisture values. Specification or project geotechnical report will reference the required method. We run both; the result establishes the target density used for field nuclear gauge or sand cone verification (ASTM D6938 / ASTM D1556) during earthwork operations.
How fast can a technician be on site in Fairbanks?
Fairbanks work is dispatched through our Seattle, WA 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 Fairbanks, AK?
Field work in Fairbanks is dispatched through the Seattle, WA regional hub, about 1518 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Fairbanks projects.
Are the technicians you send to Fairbanks 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 Alaska agencies or owners require state-specific certifications, those are confirmed in the proposal.
