Scope
What we test in Washoe 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 Washoe County
Washoe County sits in a high desert basin where elevation, temperature swings, and expansive or loose alluvial soils all work against construction materials performing as designed. Concrete placed during the region's hot summer afternoons can lose slump and gain air content faster than specifications allow, while the cold overnight temperatures that arrive even in late spring compress usable placement windows. Below grade, the valley's alluvial and volcanic-derived soils vary significantly in bearing capacity and moisture sensitivity across short distances. Developers, contractors, and engineers working on residential subdivisions, commercial pads, transportation infrastructure, and industrial facilities here need materials testing that is technically disciplined, not just administratively convenient. Our firm dispatches certified field technicians to Washoe County project sites from our Sacramento regional hub to perform ASTM-compliant concrete, aggregate, and soil testing — generating defensible data and clear reports that satisfy project specifications, owner requirements, and local agency submittals throughout the project lifecycle.
Washoe County's high desert climate — with wide diurnal temperature ranges, low humidity, and the potential for freezing temperatures well into spring — creates conditions where fresh concrete temperature and evaporation rate monitoring are critical at the time of placement. The valley's alluvial soils can include layers of varying density and plasticity that warrant careful Proctor and in-place density testing at lift-by-lift intervals during earthwork.
FAQ · Washoe County
What concrete temperature and evaporation precautions apply to pours in the Reno-Sparks area, and can your technicians flag those conditions at the time of testing?
Yes. During fresh concrete field visits, our ACI-certified technicians record concrete temperature per ASTM C1064 and ambient conditions including air temperature, relative humidity, and wind speed. When evaporation rate approaches the threshold identified in ACI 305R for hot-weather concreting or ACI 306R for cold-weather conditions, the technician documents those parameters in the field record so the contractor and engineer have contemporaneous data to support any protective measures taken.
How far in advance do I need to schedule a technician for a concrete pour or compaction test in Washoe County?
Coverage for Washoe County is dispatched through our Sacramento regional hub, approximately 112 miles away. Advance scheduling of at least 48 to 72 business hours is recommended to confirm technician availability, particularly for early morning pours or multi-day earthwork operations. We cannot guarantee same-day dispatch for Washoe County. Contact your project coordinator early in the concrete or earthwork schedule to establish a standing coverage plan.
Washoe County earthwork often encounters variable fill and native alluvial soils. How do you determine the correct compaction standard for each material?
The technician or project laboratory establishes a moisture-density relationship for each distinct soil or fill material using ASTM D698 (standard Proctor) or ASTM D1557 (modified Proctor), as specified. In-place density is then measured by nuclear gauge per ASTM D6938 or sand cone per ASTM D1556 and compared to the applicable Proctor curve. When borrow or import materials change during the project, a new Proctor is performed for that material before density acceptance testing continues.
How fast can a technician be on site in Washoe County?
Washoe County work is dispatched through our Sacramento, CA 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 Washoe County, NV?
Field work in Washoe County is dispatched through the Sacramento, CA regional hub, about 112 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Washoe County projects.
Are the technicians you send to Washoe 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 Nevada agencies or owners require state-specific certifications, those are confirmed in the proposal.
