Scope
What we test in Allentown
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 Allentown
Allentown sits within a region where construction demands respect for variable subsurface conditions — glacially influenced soils, legacy fill in redeveloping urban corridors, and freeze-thaw cycles that stress concrete from the first winter onward. Developers expanding along the Lehigh Valley's industrial and mixed-use corridors, contractors working Pennsylvania Department of Transportation specifications, and engineers stamping foundation designs all depend on test data they can defend to a project owner or a reviewing agency. Our firm dispatches ACI- and NICET-certified field technicians to Allentown-area projects through our Philadelphia regional hub, providing ASTM-compliant testing of concrete, aggregate, and soil — from fresh concrete field testing and cylinder breaks to Proctor compaction, nuclear density, and soil classification. The laboratory operates under a documented quality system, and reports are structured to support project documentation, pay-application backup, and agency submittals.
The Lehigh Valley's combination of cold winters and significant seasonal temperature swings requires careful attention to concrete placement temperatures and curing conditions; fresh concrete testing per ASTM C1064 and proper documentation of ambient conditions at time of placement are especially important for year-round work in this region. Urban redevelopment sites in Allentown may encounter variable fill or legacy industrial soils that warrant thorough classification and compaction testing before structural elements are placed.
FAQ · Allentown
What scheduling lead time should I plan for materials testing on an Allentown project?
Technicians are dispatched through our Philadelphia regional hub, approximately 48 miles from Allentown. We coordinate on a scheduled and project-based basis, so provide planned pour dates, compaction sequences, or testing milestones as early as possible. We do not guarantee same-day dispatch, and building adequate lead time into your schedule — particularly for recurring concrete cylinder programs or multi-phase earthwork — avoids gaps in your testing coverage.
How does winter weather affect concrete testing requirements on Lehigh Valley projects?
Pennsylvania winters routinely push ambient temperatures below the thresholds addressed in ACI 306R cold-weather concreting guidance. Our technicians document concrete temperature at point of delivery per ASTM C1064 and air temperature at time of testing. This data supports your cold-weather protection plan and gives the engineer of record defensible records if curing conditions are later questioned during a project dispute or inspection review.
Pennsylvania DOT projects in the Lehigh Valley require specific aggregate testing — can you support that?
Yes. We perform aggregate gradation analysis per ASTM C136 and ASTM C117, soundness per ASTM C88, and abrasion resistance per ASTM C131 or C535 as applicable. For PennDOT-governed work, verify which specific test designations and frequencies your project special provisions require, and share those with us so testing aligns with the specification — not just general practice.
How fast can a technician be on site in Allentown?
Allentown 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 Allentown, PA?
Field work in Allentown is dispatched through the Philadelphia, PA regional hub, about 48 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Allentown projects.
Are the technicians you send to Allentown 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.
