Scope
What we test in Philadelphia
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 Philadelphia
Philadelphia's built environment presents a specific set of demands on construction materials. The region's variable glacial and residual soils — including pockets of fill material common beneath urban redevelopment sites — require careful characterization before foundations are placed. Concrete work faces real seasonal pressure: summer heat accelerates set times and threatens strength gain, while Philadelphia winters push concrete placement close to ACI 306 cold-weather thresholds. Structural masonry, deep foundations, and large-scale civic and mixed-use construction are all active in this market, and each brings specification requirements that must be documented and defended. Our certified field technicians, dispatched through our Philadelphia regional hub, perform ASTM-compliant testing of fresh and hardened concrete, soil and aggregate, and site compaction — backed by a documented laboratory quality system and reporting prepared for third-party review.
Philadelphia-area sites, particularly those involving urban redevelopment or brownfield conversion, frequently encounter variable fill and disturbed soils that require thorough classification and compaction verification before structural loading. The region's freeze-thaw cycle also makes air-entrainment verification during fresh concrete testing a practical necessity on exposed flatwork and structures.
FAQ · Philadelphia
Philadelphia has a lot of urban infill and brownfield redevelopment. What soil testing do you perform to characterize fill material before we build on it?
We perform soil classification per ASTM D2487 (Unified Soil Classification System), moisture-density relationships per ASTM D698 or D1557, and in-place density testing to verify compaction. For sites with suspect fill, we can also run corrosivity testing — pH, resistivity, chloride, and sulfate — per applicable ASTM methods. All results are documented under our quality system with chain-of-custody traceability.
We're placing concrete in July in Philadelphia. What fresh concrete tests address heat and slump loss between the truck and the pour?
We test slump per ASTM C143, concrete temperature per ASTM C1064, air content per ASTM C231 (pressure method) or C173 (volumetric), and unit weight per ASTM C138 — all at point of discharge before placement. High ambient temperatures accelerate hydration; field data captured at discharge gives your project documentation that mix properties met specification at the critical moment, not at the plant.
Our Philadelphia project spec calls for both standard and early-break cylinders. How do you handle cylinder curing and transport to your lab?
Field-cast cylinders are made and initially cured per ASTM C31, which requires maintaining them at 60–80°F for the first 24 hours. We use insulated transport containers and deliver to our laboratory on a scheduled basis. Early breaks (24-hour or 3-day) are flagged and prioritized. Compressive strength testing is performed per ASTM C39, and results are reported promptly so your team can act on the data.
How fast can a technician be on site in Philadelphia?
Philadelphia work is dispatched through our Philadelphia, PA 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 Philadelphia, PA?
Field work in Philadelphia is dispatched through the Philadelphia, PA regional hub. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Philadelphia projects.
Are the technicians you send to Philadelphia 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 Pennsylvania agencies or owners require state-specific certifications, those are confirmed in the proposal.
