Scope
What we test in New London 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 New London County
New London County sits at the intersection of coastal exposure, glacially deposited soils, and a construction mix that runs from shoreline residential and marina infrastructure to institutional, healthcare, and defense-related work near the Thames River corridor. That combination puts real demands on materials testing: fill placed over variable glacial till and outwash needs documented compaction data, concrete placed through Connecticut's shoulder seasons—where morning temperatures can drop below ACI 305 and ACI 306 thresholds on the same calendar week—needs field testing records prepared for third-party review, and aggregate used in structural concrete needs gradation and quality data tied to defensible lab results. Our firm dispatches certified field technicians to New London County project sites for ASTM-compliant concrete, aggregate, and soil testing, with laboratory analysis run under a documented quality system and reporting designed to satisfy engineer, owner, and authority-having-jurisdiction requirements.
Glacial till, outwash sands, and coastal fill are common subsurface conditions across New London County, making Proctor reference testing and in-place density verification critical steps before subgrade acceptance. Connecticut's climate also means concrete placement windows in late fall and early spring require close attention to fresh concrete temperature per ACI 305R and ACI 306R guidelines.
FAQ · New London County
What soil classification and Proctor testing do you perform, and why does it matter for New London County fill projects?
We perform USCS and AASHTO soil classification along with Standard and Modified Proctor compaction testing per ASTM D698 and ASTM D1557. In New London County, where glacial outwash sands and variable till are common borrow and subgrade materials, establishing an accurate moisture-density relationship before earthwork begins is essential for meaningful field compaction verification and subgrade acceptance documentation.
How do you handle cold-weather concrete testing requirements for projects running into Connecticut's fall and winter months?
Field technicians measure and document fresh concrete temperature at point of discharge per ASTM C1064, alongside slump, air content, and unit weight. When temperatures approach ACI 306R thresholds, those readings become part of the official field record. Cylinder sets are protected and transported in compliance with ASTM C31 curing requirements so cold-weather conditions do not compromise compressive strength results at 7- and 28-day breaks.
What nuclear density gauge testing covers in the field, and what does New London County's coastal construction environment mean for that work?
Nuclear density testing per ASTM D6938 provides in-place wet density and moisture content for compacted fill and subgrade. In coastal New London County, where proximity to tidal areas and high groundwater can affect fill moisture conditions, having calibrated gauge readings tied to a project-specific Proctor curve gives the geotechnical engineer and contractor documented evidence that density specifications are actually being met.
How fast can a technician be on site in New London County?
New London County work is dispatched through our Boston, MA 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 London County, CT?
Field work in New London County is dispatched through the Boston, MA regional hub, about 87 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large New London County projects.
Are the technicians you send to New London 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 Connecticut agencies or owners require state-specific certifications, those are confirmed in the proposal.
