Scope
What we test in Rock Springs
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 Rock Springs
Rock Springs sits in Wyoming's high desert, where construction projects contend with alkaline and expansive soils, wide temperature swings between seasons, and high-altitude conditions that affect concrete set times and curing behavior. Whether you are building energy-sector infrastructure, commercial facilities, or civil improvements across Sweetwater County, the structural integrity of your project depends on materials that actually meet specification — not materials assumed to meet it. Our firm dispatches certified field technicians from our Salt Lake City regional hub to Rock Springs and the surrounding area on a scheduled and project-based basis, covering fresh concrete testing, soil compaction and classification, aggregate evaluation, and laboratory analysis under a documented quality system. We deliver clear, defensible test reports tied to the ASTM designations your project specifications require, giving contractors, engineers, and owners the documentation needed to keep work moving and withstand agency review.
Soils across the Rock Springs area and broader Sweetwater County commonly exhibit alkaline characteristics and variable composition, which can affect both subgrade performance and the long-term durability of embedded concrete and metallic elements. Wyoming's climate introduces significant freeze-thaw cycles and temperature extremes that make proper concrete placement documentation — including air content, slump, and early-age cylinder breaks — especially important for year-round construction.
FAQ · Rock Springs
How does high-altitude cold weather in Rock Springs affect concrete testing requirements on my project?
At Rock Springs elevations and during Wyoming's cold seasons, concrete is at elevated risk for inadequate hydration and early freeze damage. ACI 306R provides cold-weather concreting guidance that should inform your placement plan. Field testing per ASTM C143, C231, and C1064 documents temperature, slump, and air content at the point of discharge, and cylinder curing conditions must be controlled to produce results representative of in-place strength.
Can you perform Proctor compaction testing on soils typical to the Rock Springs area before earthwork begins?
Yes. Laboratory Proctor testing per ASTM D698 (Standard) or ASTM D1557 (Modified) establishes the moisture-density relationship for your specific borrow or native material before field compaction begins. Because soils in this region can vary in gradation and fines content, running a Proctor on the actual material being placed — not a generic assumption — gives your compaction specification a defensible baseline for nuclear or sand-cone density testing in the field.
How do alkaline soil conditions in Sweetwater County affect what soil testing I should specify?
Alkaline soils common to this region can accelerate corrosion of buried metallic elements and degrade portland cement concrete over time. Soil corrosivity testing — including pH, resistivity, sulfate content, and chloride content — helps engineers select appropriate concrete mix designs, protective coatings, or backfill materials. ASTM G57 covers field resistivity measurement; sulfate content is evaluated per ASTM D4327 or equivalent, and ACI 318 Table 19.3.2 ties sulfate exposure class to mix requirements.
How fast can a technician be on site in Rock Springs?
Rock Springs 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 Rock Springs, WY?
Field work in Rock Springs is dispatched through the Salt Lake City, UT regional hub, about 151 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Rock Springs projects.
Are the technicians you send to Rock Springs 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 Wyoming agencies or owners require state-specific certifications, those are confirmed in the proposal.
