Scope
What we test in New York
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 New York
New York City's construction environment is among the most demanding in the country. Tight urban sites, deep foundation work through variable glacial soils and fill, high-rise concrete poured in weather that swings from summer heat to hard winter freezes, and rigorous oversight from the New York City Department of Buildings all mean that materials testing is not a paperwork formality — it is a project-control tool. Our certified technicians, dispatched through our New York regional hub, perform ASTM-compliant field and laboratory testing of concrete, aggregate, and soil for contractors, developers, and engineers working across the five boroughs and the broader metro. From fresh concrete testing and cylinder breaks to Proctor compaction, nuclear density gauge readings, and soil classification and corrosivity, every service is executed under a documented quality system and reported with the detail your project record requires.
New York City's subsurface conditions vary considerably across the boroughs, with glacially deposited materials, variable fill, and compressible organic layers common in many areas — conditions that make proper soil classification and compaction verification particularly consequential for foundation and earthwork acceptance. Concrete work in the region must account for a full range of seasonal temperatures, and cold-weather concreting protections per ACI 306 and hot-weather precautions per ACI 305 are practical considerations on active New York projects throughout the year.
FAQ · New York
New York City requires special inspection for concrete — how does materials testing connect to that requirement?
Under IBC Chapter 17 and the NYC Building Code, concrete for structural elements typically requires special inspection, which includes field testing of fresh concrete and strength verification through cylinder breaks. Our technicians perform these tasks to ASTM C172, C143, C138, C231, and C39, generating the test records your special inspection program and statement of special inspections require for DOB compliance.
Can you support high-rise concrete pours with multiple placements in a single shift?
Yes. For projects with large pour volumes or multiple placement points — common in New York high-rise construction — we coordinate technician coverage to match your pour schedule. Sampling frequency follows ASTM C172 requirements and your project specification, and all field tests, including slump, air content, unit weight, and temperature, are documented per ASTM C1064 for each sampling event.
What should I know about soil compaction testing for urban infill or below-grade work in New York?
Urban infill sites in New York often involve existing fill of uncertain composition alongside native glacial soils. We establish compaction baselines using ASTM D698 or D1557 Proctor testing in the lab, then verify field density with nuclear density gauge testing per ASTM D6938. Where fill material is inconsistent, additional classification testing per ASTM D2487 helps confirm suitability before compaction acceptance.
How fast can a technician be on site in New York?
New York work is dispatched through our New York, NY 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 New York, NY?
Field work in New York is dispatched through the New York, NY regional hub. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large New York projects.
Are the technicians you send to New York 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 New York agencies or owners require state-specific certifications, those are confirmed in the proposal.
