Scope
What we test in Austin
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 Austin
Austin's construction market puts real demands on materials testing. Expansive clay soils — common across much of the greater Austin area — shift seasonally with moisture changes, making proper soil classification and compaction verification essential before any slab or foundation goes down. Summer heat pushes ambient and concrete temperatures high enough to affect hydration rates, workability, and ultimately compressive strength, so fresh concrete testing timed to actual placement conditions is not optional. Add the pace of residential, commercial, and infrastructure development across the metro, and the margin for undocumented or inadequate testing is narrow. Our Austin regional dispatch hub puts ACI- and NICET-certified field technicians on your project for scheduled and project-based coverage, performing ASTM-compliant field and laboratory testing of concrete, soil, and aggregate under a documented quality system. Results are reported in a format prepared for third-party review, special inspection programs, and engineer of record scrutiny — so your project keeps moving without documentation gaps.
Much of the Austin area is underlain by expansive Vertisol-type clays and transition-zone soils that require careful Proctor baseline work and density verification to catch moisture-related settlement risks before they become structural problems. High summer temperatures routinely affect fresh concrete placement windows, making slump, air content, and temperature measurements at point of discharge — per ASTM C172 and C1064 — particularly consequential on local projects.
FAQ · Austin
Austin's expansive clay soils are well known — what soil testing do you perform to characterize them before foundation work begins?
We perform Atterberg limits (ASTM D4318), grain-size analysis (ASTM D6913/D7928), and soil classification (ASTM D2487) to characterize plasticity and swell potential. Standard Proctor (ASTM D698) or Modified Proctor (ASTM D1557) testing establishes the moisture-density relationship used to set compaction targets. These results give the geotechnical engineer and foundation designer defensible baseline data before earthwork begins.
Concrete temperatures in Austin can exceed spec limits during summer pours — how do you handle temperature compliance in the field?
Our technicians measure fresh concrete temperature at point of discharge using a calibrated thermometer per ASTM C1064 on every sampled load. When readings approach or exceed specification limits — commonly 90°F or 95°F depending on project specs — that data is recorded immediately and reported. We do not make pour/no-pour calls, but our documentation gives the engineer of record the information needed to act in real time.
What compaction testing method is used on Austin-area projects, and when is nuclear gauge appropriate versus other methods?
Field density is most commonly measured with a nuclear moisture-density gauge per ASTM D6938, which gives rapid results suited to earthwork production schedules. For projects where nuclear methods are restricted or prohibited, we can perform the sand-cone method per ASTM D1556. Test frequency and method are typically specified by the geotechnical engineer of record or the project's special inspection program. Our technicians are trained on both methods.
How fast can a technician be on site in Austin?
Austin work is dispatched through our Austin, TX 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 Austin, TX?
Field work in Austin is dispatched through the Austin, TX regional hub. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Austin projects.
Are the technicians you send to Austin 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.
