Scope
What we test in Matanuska-Susitna Borough
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 Matanuska-Susitna Borough
Building in the Matanuska-Susitna Borough means working with some of the most demanding ground and weather conditions in North America. Glacially deposited soils — ranging from silty loam in valley floors to coarser gravels along outwash plains — vary significantly over short distances, making soil classification and compaction verification critical on virtually every site. Freeze-thaw cycles are deep and prolonged, placing real pressure on concrete mix design, placement timing, and cold-weather protection protocols. Our firm provides scheduled and project-based construction materials testing throughout the Mat-Su Borough, dispatched through our Seattle regional hub. Certified field technicians perform fresh concrete testing, cylinder fabrication, aggregate evaluation, Proctor compaction, nuclear density, and soil classification — all conducted under a documented quality system with reporting prepared for third-party review. Coverage is planned in advance; contact us early in your project schedule.
Glacially influenced soils common to the Matanuska-Susitna Valley can exhibit significant variability in gradation, plasticity, and frost susceptibility within a single project footprint, making thorough soil classification under ASTM D2487 and compaction control under ASTM D1557 or D698 especially important. Alaska's extended cold seasons require careful attention to ACI 306R cold-weather concreting guidelines, and placing and curing schedules should be coordinated with testing coverage well ahead of pours.
FAQ · Matanuska-Susitna Borough
How do freeze-thaw conditions in the Mat-Su Borough affect when and how you test fresh concrete?
When ambient or substrate temperatures fall at or near freezing, fresh concrete testing — slump (ASTM C143), air content (ASTM C231), and concrete temperature (ASTM C1064) — becomes especially important. ACI 306R establishes thresholds for placement temperatures and protection requirements. Our technicians document conditions at the time of each pour so your cold-weather concrete records are complete and defensible if questioned by the engineer of record or a reviewing agency.
Can you perform soil classification on the variable glacial soils common to the Matanuska Valley?
Yes. Technicians collect samples for laboratory classification under ASTM D2487 (Unified Soil Classification System), including Atterberg limits (ASTM D4318) and grain-size analysis (ASTM D6913 / D7928). Glacially derived soils in this region can shift from well-graded gravels to frost-susceptible silts within a short lateral distance, so sample locations and frequencies should be discussed with the project geotechnical engineer before fieldwork begins.
What compaction testing method applies to aggregate base and fill materials used in Mat-Su Borough road and site work?
Most project specifications reference either ASTM D698 (standard effort) or ASTM D1557 (modified effort) for laboratory Proctor to establish maximum dry density. Field density is then verified by nuclear gauge under ASTM D6938 or, where specified, sand-cone per ASTM D1556. The applicable method and required compaction percentage should be confirmed in your project geotechnical report or the governing agency's standard specifications before testing begins.
How fast can a technician be on site in Matanuska-Susitna Borough?
Matanuska-Susitna Borough 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 Matanuska-Susitna Borough, AK?
Field work in Matanuska-Susitna Borough is dispatched through the Seattle, WA regional hub, about 1433 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Matanuska-Susitna Borough projects.
Are the technicians you send to Matanuska-Susitna Borough 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.
