Scope
What we test in Eugene
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 Eugene
Eugene sits in the southern Willamette Valley, where a wet maritime climate, expansive clay-bearing soils, and a construction market spanning university facilities, mid-rise mixed-use, and industrial tilt-up all place real demands on materials quality. Concrete placed during Oregon's long rainy season must meet temperature, slump, and air-entrainment tolerances that shift with the weather; subgrade soils that perform well during summer grading can behave very differently after winter saturation. Getting those materials decisions right requires field and laboratory data you can defend to the owner, the engineer of record, and the building department. We dispatch certified technicians to Eugene project sites for ASTM-compliant fresh concrete testing, compressive strength cylinder programs, aggregate evaluation, Proctor compaction and nuclear density, soil classification, and soil corrosivity testing — all reported under a documented quality system and formatted to support your schedule and your specifications.
The Willamette Valley's fine-grained, moisture-sensitive soils — including deposits with moderate to high plasticity — make accurate Proctor moisture-density relationships and field density verification particularly important for site work and structural fill. Eugene's cool, wet winters also extend the seasonal window when concrete mix temperature monitoring and protection planning become specification-relevant tasks on exposed flatwork and foundation pours.
FAQ · Eugene
Our project is in Eugene but you're headquartered in Texas — how does dispatch actually work for our site visits?
Field coverage for Eugene is coordinated through our Seattle, WA regional hub, approximately 248 miles away. Technicians are scheduled on a project-based or standing-schedule basis. We plan visits around your pour schedule, compaction sequence, or subgrade milestones. Because same-day dispatch is not guaranteed from this hub, we ask that you contact us as early as possible — ideally with 48 to 72 hours of advance notice for routine visits.
Willamette Valley soils can be pretty wet heading into winter. How do you handle nuclear density testing when soils are near or above optimum moisture?
Nuclear density testing per ASTM D6938 measures both wet density and moisture content in the field. When in-place moisture is elevated — common in Willamette Valley clay-bearing fills late in the wet season — the gauge readings are compared directly against the lab-established moisture-density curve from ASTM D698 or D1557 to determine whether compaction meets the specified relative density. Results outside tolerance are flagged immediately in the field report.
The City of Eugene or Lane County may require special inspection on our project. Does materials testing feed into that requirement?
Yes. Under IBC Chapter 17, special inspection programs for concrete and soil often include the same field tests — slump, air content, temperature, unit weight per ASTM C172 and C143, and cylinder fabrication per ASTM C31 — that make up a standard materials testing scope. We can structure our testing program to align with your Statement of Special Inspections, and our reports are formatted to support the documentation your building official will review at close-out.
How fast can a technician be on site in Eugene?
Eugene 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 Eugene, OR?
Field work in Eugene is dispatched through the Seattle, WA regional hub, about 248 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Eugene projects.
Are the technicians you send to Eugene 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 Oregon agencies or owners require state-specific certifications, those are confirmed in the proposal.
