Scope
What we test in San Juan 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 San Juan County
San Juan County sits in the heart of the San Juan Basin, where high-desert conditions — wide daily temperature swings, low humidity, and an arid climate — create real challenges for concrete placement and soil work. Concrete can lose slump faster than anticipated in summer heat, and expansive or variable alluvial soils common to the Four Corners region demand thorough characterization before earthwork begins. Energy, infrastructure, and commercial construction throughout Farmington and the surrounding area depend on materials data prepared for third-party review from owners, engineers, and public agencies. Our firm provides ASTM-compliant field and laboratory testing of concrete, aggregate, and soil across San Juan County, dispatched through our Denver regional hub with scheduled and project-based coverage. Certified technicians handle everything from fresh concrete testing and cylinder breaks to Proctor compaction, nuclear density, and soil classification — all under a documented quality system that produces defensible, traceable results.
Soils across the San Juan Basin can vary from loose alluvial deposits near the Animas and San Juan Rivers to stiffer sedimentary formations, making site-specific soil classification and compaction verification especially important before placing footings or engineered fill. The region's arid climate and high UV exposure also mean concrete mix timing, curing, and testing windows should be planned carefully to comply with ACI 305R hot-weather concreting guidance during summer months.
FAQ · San Juan County
What soil classification tests do you perform, and why do they matter for San Juan County projects?
We perform USCS and AASHTO classification testing per ASTM D2487 and D3282, including Atterberg limits (ASTM D4318) and gradation (ASTM D6913/D7928). In the San Juan Basin, where alluvial and sedimentary soils can vary significantly across a single site, proper classification informs bearing capacity assumptions, fill selection, and compaction specifications — reducing the risk of costly post-construction settlement.
How do hot summers and low humidity in the Farmington area affect concrete cylinder sampling and curing?
High temperatures and low relative humidity accelerate moisture loss and hydration, which can compromise strength development if cylinders are not handled correctly. Field technicians follow ASTM C31 initial curing requirements — maintaining cylinders between 60°F and 80°F for the first 24 hours and protecting them from vibration and temperature extremes — before transport to the laboratory for standard moist curing to 28 days.
Can you perform Proctor testing on the specific fill material our earthwork contractor plans to bring to the San Juan County site?
Yes. We run standard or modified Proctor tests per ASTM D698 or D1557 on submitted samples. Because fill materials can vary — including caliche-bearing soils and imported granular materials common to New Mexico projects — establishing an accurate moisture-density relationship for the actual material used is essential before nuclear density gauge or sand-cone field compaction testing begins under ASTM D6938 or D1556.
How fast can a technician be on site in San Juan County?
San Juan County work is dispatched through our Denver, CO 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 San Juan County, NM?
Field work in San Juan County is dispatched through the Denver, CO regional hub, about 272 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large San Juan County projects.
Are the technicians you send to San Juan 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 New Mexico agencies or owners require state-specific certifications, those are confirmed in the proposal.
