Scope
What we test in Philadelphia 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 Philadelphia County
Philadelphia County sits on a dense urban fabric of row housing, high-rise residential, institutional campuses, and infrastructure renewal — much of it built on variable fill, glacially influenced soils, and weathered schist and gneiss of the Piedmont upland. That subsurface variability, combined with Pennsylvania's four-season climate where winter concrete placements demand close attention to temperature and curing conditions, makes materials testing something specification committees and building officials take seriously here. Our technicians, dispatched through our Philadelphia regional hub, perform ASTM-compliant field and laboratory testing of concrete, soil, and aggregate on projects across the county. Fresh concrete testing, cylinder breaks, Proctor compaction, nuclear density, aggregate gradation, soil classification, and soil corrosivity — all executed under a documented quality system and returned to you in clear, defensible reports your project record can stand behind.
Philadelphia County's subsurface frequently transitions between urban fill of variable composition and native residual soils derived from Piedmont metamorphic rock, making soil classification and compaction verification especially important on grading and foundation work. Pennsylvania's cold winters require concrete placements to be monitored against ACI 306R cold-weather guidelines, and summer heat and humidity can compress the working window for air-entrained mixes on flatwork.
FAQ · Philadelphia County
My Philadelphia project sits on urban fill. What soil testing do you recommend before we compact and build on it?
Urban fill in Philadelphia County is notoriously inconsistent — demolition rubble, cinders, and mixed debris are common. We typically recommend visual soil classification per ASTM D2488, Unified Soil Classification per ASTM D2487, and moisture-density relationships via ASTM D698 or D1557 to establish a valid compaction baseline before any structural fill or foundation bearing work proceeds. Corrosivity testing may also apply if buried utilities or reinforced earth structures are involved.
Pennsylvania winters are real. Can you help us meet spec on cold-weather concrete placements in Philadelphia?
Yes. Our ACI-certified field technicians measure concrete temperature at point of discharge per ASTM C1064 and verify air content per ASTM C231 on every placement visit. We document conditions against the thresholds in ACI 306R and your project specification, giving you a defensible temperature and protection record. We do not make the curing decisions — that is the contractor's responsibility — but our field data supports those decisions and protects the project record.
The Philadelphia Department of Licenses and Inspections requires a special inspection program. How does materials testing fit in?
IBC Chapter 17 requires a Statement of Special Inspections approved before permit issuance, and concrete and soil compaction are common line items. Our field technicians perform the observations and tests called out in your approved inspection program, document results on inspection reports that reference the applicable ASTM designations, and provide the data your special inspector of record needs to issue the required compliance documentation to the City.
How fast can a technician be on site in Philadelphia County?
Philadelphia County 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 County, PA?
Field work in Philadelphia County 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 County projects.
Are the technicians you send to Philadelphia 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 Pennsylvania agencies or owners require state-specific certifications, those are confirmed in the proposal.
