Scope
What we test in El Paso
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 El Paso
El Paso sits in a high-desert environment where caliche-rich soils, expansive clays, and arid conditions create real testing challenges for every foundation, pavement, and structural pour. Summer concrete placement can see ambient temperatures exceeding 100 °F, requiring close attention to fresh concrete temperature limits under ACI 305R and careful management of water-to-cementitious ratios. Subsurface soils frequently demand thorough Proctor compaction curves and field density verification before any slab or structural fill is accepted. Our firm dispatches certified field technicians to El Paso project sites on a scheduled and project-based basis, covering fresh concrete testing, compressive strength cylinder breaks, aggregate gradation and quality, Proctor and nuclear gauge density, soil classification, and soil corrosivity analysis. Every service is performed to applicable ASTM standards by ACI- and NICET-certified technicians, with reporting built to hold up through owner review, special inspection submittals, and agency closeout.
El Paso's soils commonly include caliche layers and desert-derived materials with variable compressibility, making Proctor reference curves and field density verification critical for pavement subgrades and building pads. Extreme summer heat accelerates concrete set times and can elevate fresh concrete temperatures beyond ACI 301 and ACI 305R thresholds, making slump, temperature, and air content field checks especially consequential during warm-weather placement seasons.
FAQ · El Paso
Our El Paso project has caliche layers in the subgrade. What testing do we need to confirm the material is suitable for structural fill?
Caliche can vary widely in strength and compressibility. We perform soil classification under ASTM D2487, moisture-density relationship testing under ASTM D698 or D1557 depending on compaction energy specified, and field density verification by nuclear gauge per ASTM D6938. If the specification requires additional durability or swell testing, those can be scoped into the program before grading begins.
How does your firm handle concrete testing when El Paso summer temperatures push fresh concrete above allowable limits?
Field technicians measure and document fresh concrete temperature at point of discharge per ASTM C1064 on every sampled load. When temperatures approach or exceed limits referenced in ACI 301 or project-specific hot-weather plans under ACI 305R, that data goes directly into the field report so the contractor and engineer of record can act on it. We also record slump (ASTM C143), air content (ASTM C231), and unit weight (ASTM C138).
What compressive strength cylinder curing and break schedule is standard for El Paso projects, and can that schedule be adjusted?
Standard practice follows ASTM C31 for field-cured or standard laboratory-cured cylinders, with break sets typically at 7 and 28 days per ASTM C39. Some El Paso project specifications or structural engineer requirements call for additional breaks at 3 or 56 days. We match the break schedule to your specification and report each set with the cylinder ID, cure method, age at break, and measured compressive strength.
How fast can a technician be on site in El Paso?
El Paso work is dispatched through our Phoenix, AZ 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 El Paso, TX?
Field work in El Paso is dispatched through the Phoenix, AZ regional hub, about 345 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large El Paso projects.
Are the technicians you send to El Paso 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 Texas agencies or owners require state-specific certifications, those are confirmed in the proposal.
