Scope
What we test in New Haven
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 Haven
New Haven sits at the intersection of coastal exposure, heavy institutional construction, and a substrate that keeps geotechnical engineers honest. The region's glacially deposited soils — ranging from compact glacial till to variable fill in and around the harbor — demand rigorous characterization before footings are placed or embankments compacted. Yale University's ongoing campus expansion, mixed-use development along the waterfront, and infrastructure rehabilitation throughout the city create a sustained need for materials testing prepared for third-party review. Our certified technicians dispatch through the New York regional hub to cover scheduled and project-based assignments across New Haven and the surrounding Connecticut shoreline corridor. From fresh concrete testing and cylinder curing to Proctor compaction curves and soil classification, every test follows applicable ASTM standards and is documented under a structured quality system — so your data is defensible when it matters.
Southern Connecticut's freeze-thaw cycle and humid coastal climate place real demands on concrete mix design and curing practice, making field testing at the point of placement — slump, air content, and temperature per ASTM C143, C231, and C1064 — especially consequential for durability. Glacially influenced soils across the New Haven area commonly vary over short distances, reinforcing the value of systematic classification and compaction verification rather than assumptions carried from one area of a site to another.
FAQ · New Haven
My specification requires air-entrained concrete for exterior flatwork. How does your field testing verify that?
Field technicians measure air content at the point of discharge using a pressure meter per ASTM C231 for normal-weight aggregate concrete, or ASTM C173 for lightweight aggregate. Results are recorded alongside temperature (ASTM C1064) and slump (ASTM C143). Given Connecticut's freeze-thaw exposure, confirming that air content falls within the specified range — typically 5 to 7 percent for severe exposure — is a standard part of every fresh concrete testing visit.
We're working with fill soils on a site near the New Haven waterfront that may contain variable or potentially contaminated material. What soil classification work can you provide?
Technicians can perform grain size analysis per ASTM D6913 and Atterberg limits per ASTM D4318 to classify soils under the Unified Soil Classification System (ASTM D2487). If corrosivity screening is needed for buried elements, chloride, sulfate, pH, and resistivity testing are also available. Classification results inform whether material meets your project specification before it is placed and compacted.
Connecticut winters can interrupt concrete pours and curing schedules. Can you test concrete placed during cold-weather conditions?
Yes. During cold-weather operations, concrete temperature at delivery is measured per ASTM C1064, and ACI 306R cold-weather placing guidelines inform interpretation of those readings. Standard cylinder sets are cast per ASTM C31, which includes specific provisions for initial curing temperatures in cold conditions. Consistent field documentation during this period supports decisions about when forms can be stripped and heating equipment removed.
How fast can a technician be on site in New Haven?
New Haven 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 Haven, CT?
Field work in New Haven is dispatched through the New York, NY regional hub, about 70 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large New Haven projects.
Are the technicians you send to New Haven 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 Connecticut agencies or owners require state-specific certifications, those are confirmed in the proposal.
