Scope
What we test in Aurora
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 Aurora
Aurora sits on the High Plains at roughly 5,400 feet, where contractors deal with expansive clays and claystone-bearing soils, rapid moisture swings, and temperature differentials that can stress fresh concrete before it ever reaches design strength. Winter cold fronts arrive fast, and summer afternoon heat accelerates set times in ways that punish poorly timed placements. Getting the materials data right — before placement, during compaction, and at 28-day break — is not a formality; it protects schedule, budget, and structural performance. Our Denver-area hub dispatches ACI- and NICET-certified technicians to Aurora job sites for ASTM-compliant field and laboratory testing of concrete, soil, and aggregate. The laboratory operates under a documented quality system. Reports are written to be defensible under project specifications and agency review, giving contractors, developers, and engineers the data they need to move work forward with confidence.
Aurora-area soils commonly include expansive clays and weathered claystone that are sensitive to moisture change — conditions that make accurate Proctor compaction curves and field density verification critical on every lift. Colorado's wide seasonal temperature range also requires attention to cold- and hot-weather concrete provisions under ACI 305R and ACI 306R when scheduling placements.
FAQ · Aurora
Aurora sits at high altitude with strong UV and low humidity — does that affect how you evaluate fresh concrete on site?
Yes. At roughly 5,400 feet, lower atmospheric pressure and low relative humidity accelerate surface evaporation and can shorten workable time. Our technicians perform slump (ASTM C143), air content (ASTM C231), temperature (ASTM C1064), and unit weight (ASTM C138) immediately at the point of discharge, following ASTM C172 sampling protocols, so results reflect actual placement conditions rather than conditions minutes later.
We have a commercial foundation project on expansive soils in Aurora — what soil testing do you recommend before we place?
For expansive clay and claystone profiles common to the Aurora area, we typically recommend Proctor compaction testing (ASTM D698 or D1557 depending on compactive effort specified), Atterberg limits (ASTM D4318) for soil classification under ASTM D2487, and swell-consolidation testing if the geotechnical report requires it. These results inform earthwork specifications and give the structural engineer defensible design input.
What nuclear density gauge work do you perform during earthwork phases on Aurora projects, and what does a compaction report include?
Field density testing is performed using a nuclear gauge per ASTM D6938, referenced to a project-specific Proctor curve. Each report identifies test location, depth, in-place dry density, moisture content, and percent compaction relative to the specified standard. Reports note the applicable ASTM method and lift reference so the project record is complete for owner, contractor, and agency review.
How fast can a technician be on site in Aurora?
Aurora 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 Aurora, CO?
Field work in Aurora is dispatched through the Denver, CO regional hub, about 9 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Aurora projects.
Are the technicians you send to Aurora 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 Colorado agencies or owners require state-specific certifications, those are confirmed in the proposal.
