Scope
What we test in Lane 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.
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 Lane County
Lane County's built environment sits on a foundation of geological variety — from the clay-heavy valley soils of the Willamette floor to the volcanic and alluvial deposits that characterize the Cascade foothills to the east. Add a wet season that runs well into spring, and construction teams face real consequences when soil compaction, concrete placement, or aggregate quality isn't documented with precision. Moisture-sensitive subgrades can shift between acceptable and failing density targets across a single site visit. Cold, wet conditions during concrete pours demand that fresh concrete testing — slump, air content, temperature, and unit weight — be performed by technicians who understand what those numbers mean in context. Our firm dispatches ACI- and NICET-certified field technicians to Lane County projects on a scheduled and project-based basis, performing ASTM-compliant testing of concrete, soil, and aggregate with results reported in formats your project record, your engineer, and Oregon agency reviewers can rely on.
Willamette Valley soils in Lane County are frequently fine-grained and moisture-sensitive, making Proctor compaction testing and field density verification critical steps before and during earthwork — particularly through the region's extended wet season, which can delay or complicate achieving specified compaction targets. Concrete work performed during cooler, wet months requires careful attention to fresh concrete temperatures and mix performance to remain within project specification tolerances.
FAQ · Lane County
Lane County gets significant rain through spring — how does that affect scheduling soil compaction testing on my project?
Wet conditions directly affect whether fine-grained soils can achieve specified compaction. We schedule field density testing — typically nuclear gauge testing per ASTM D6938 or sand cone per ASTM D1556 — around your earthwork windows. If subgrade moisture exceeds optimum, we document it and alert your team so you can make informed decisions before placing structural fill or pavement sections.
What Proctor test should I specify for the silty, fine-grained soils common in the Willamette Valley?
For fine-grained cohesive soils, the Standard Proctor (ASTM D698) is most commonly specified and provides the moisture-density relationship your compaction targets reference. If your specification or geotechnical engineer requires Modified Proctor (ASTM D1557) — common for pavement subbase or structural fill — we perform that as well. Confirm with your geotech which method your project documents require.
Can you perform concrete cylinder breaks for a pour happening in Eugene during a cold stretch in January or February?
Yes. Technicians sample fresh concrete per ASTM C172, cast cylinders per ASTM C31, and record concrete temperature at placement — a critical data point when ambient temperatures approach or fall below 50°F. ACI 306 cold-weather concreting thresholds inform what we document. Cylinders are transported under controlled conditions to the laboratory for curing and compression testing per ASTM C39.
How fast can a technician be on site in Lane County?
Lane County 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 Lane County, OR?
Field work in Lane County 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 Lane County projects.
Are the technicians you send to Lane 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 Oregon agencies or owners require state-specific certifications, those are confirmed in the proposal.
