Scope
What we test in Ada 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 Ada County
Ada County is one of the fastest-growing counties in the United States, and that growth shows up in the ground before it shows up in the skyline. The Treasure Valley's mix of silty alluvial soils and occasional expansive clays demands rigorous compaction verification and soil classification before a slab is poured or a wall is backfilled. Add the region's wide seasonal temperature swings — cold winters, hot dry summers — and concrete placement windows require careful attention to fresh concrete temperature, air content, and water-cementite ratio to meet durability requirements. Our firm dispatches certified field technicians from our Salt Lake City regional hub to cover scheduled and project-based assignments across Ada County. We perform ASTM-compliant testing of soils, aggregate, and concrete in the field and in a laboratory that operates under a documented quality system. Every report is structured to support your project documentation, agency submittals, and defensible quality records from groundbreaking through substantial completion.
The Treasure Valley's alluvial and silty soils can vary in density and moisture sensitivity across short distances, making lift-by-lift compaction verification using Proctor standards and nuclear density gauge readings a practical necessity rather than a formality. Idaho's cold winters also create meaningful cold-weather concreting conditions that can affect set time and early strength gain, making field-measured concrete temperature and cylinder curing documentation important for project compliance.
FAQ · Ada County
My Ada County project has silty soils that are hard to compact at consistent moisture. What testing approach helps manage this?
Silty soils common to Treasure Valley alluvial deposits are sensitive to moisture variation, which directly affects achievable density. We establish the moisture-density relationship using ASTM D698 (Standard Proctor) or ASTM D1557 (Modified Proctor) depending on your specification, then verify field compaction with a nuclear density gauge per ASTM D6938. Knowing the optimum moisture curve lets your earthwork crew make real-time adjustments rather than discover failures at testing.
How far in advance do I need to schedule a technician for concrete pours in Ada County?
Technicians for Ada County are dispatched from our Salt Lake City regional hub. We recommend scheduling concrete field testing visits at least 48 to 72 hours in advance for planned pours. This allows dispatch coordination and helps ensure a certified ACI Field Testing Technician Grade I is confirmed for your placement window. We cannot guarantee same-day response, so early scheduling is the most reliable approach for your project timeline.
What cold-weather concreting documentation does a field testing visit capture for pours in winter months?
During cold-weather placements our technician records fresh concrete temperature per ASTM C1064 alongside slump (ASTM C143), air content (ASTM C231), and unit weight (ASTM C138) at the point of discharge. Cylinder sets are made per ASTM C31, and field curing conditions are documented. This record supports your compliance with ACI 306R cold-weather guidelines and provides defensible evidence for the engineer of record and any special inspection program.
How fast can a technician be on site in Ada County?
Ada County work is dispatched through our Salt Lake City, UT 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 Ada County, ID?
Field work in Ada County is dispatched through the Salt Lake City, UT regional hub, about 296 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Ada County projects.
Are the technicians you send to Ada 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 Idaho agencies or owners require state-specific certifications, those are confirmed in the proposal.
