Scope
What we test in Travis 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 Travis County
Travis County is in the middle of one of the most sustained construction cycles in the country. Infrastructure expansion, mixed-use development along major corridors, and continued residential subdivision activity are pushing volume across geotechnical and structural scopes simultaneously. The region's expansive clay soils — common throughout the Texas Hill Country transition zone — place real demands on earthwork quality control, and Central Texas heat accelerates concrete hydration in ways that compress placement windows and complicate curing. Getting materials testing right here is not administrative box-checking; it directly affects structural performance and schedule. Our Austin-area hub dispatches ACI- and NICET-certified field technicians to Travis County project sites for ASTM-compliant concrete, aggregate, and soil testing, all supported by a laboratory operating under a documented quality system. Reports are written to be defensible at the plan-review and dispute-resolution level — the kind of documentation contractors, developers, and engineers can rely on through every project phase.
Travis County soils frequently include high-plasticity clays that swell and shrink with seasonal moisture changes, making Proctor compaction baselines and field density verification especially consequential for subgrade and embankment work. Central Texas summers also create elevated ambient temperatures that can raise fresh concrete temperatures above threshold limits, requiring closer monitoring of placement conditions in accordance with ACI 305 hot-weather concreting guidance.
FAQ · Travis County
Our Travis County project involves deep fill over expansive clay. What soil testing do we actually need before we start placing?
At minimum, expect moisture-density relationship testing per ASTM D698 or D1557 to establish your compaction target, plus soil classification under ASTM D2487 to characterize plasticity and expansion potential. For highly plastic clays common in this region, a swell or Atterberg limits series is often warranted to support the geotechnical engineer's recommendations before any fill placement begins.
What concrete compressive strength testing schedule is typical for projects in Travis County under City of Austin or Travis County standards?
Frequency requirements are set by the project specification and the authority having jurisdiction, not a single universal rule. A common baseline is one set of cylinders per 50 cubic yards or per day of placement, with breaks at 7 and 28 days per ASTM C39. Our technicians document all sampling and fabrication conditions in the field record to support both the break data and any IBC Chapter 17 special inspection requirement.
Concrete pours in Austin summers can run into temperature and slump problems. How do you handle hot-weather field testing?
Fresh concrete testing per ASTM C172 (sampling), C143 (slump), C1064 (temperature), and C231 or C173 (air content) is performed at the point of delivery. When temperatures approach or exceed ACI 305R thresholds, our technicians document concrete temperature alongside ambient conditions. That field data becomes part of the test record and supports any placement decisions the engineer of record needs to make.
How fast can a technician be on site in Travis County?
Travis County 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 Travis County, TX?
Field work in Travis County 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 Travis County projects.
Are the technicians you send to Travis 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 Texas agencies or owners require state-specific certifications, those are confirmed in the proposal.
