Scope
What we test in Kent 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 Kent County
Kent County sits at the heart of Rhode Island's Narragansett Bay watershed, where glacially deposited soils — ranging from compact gravels and sands near the bay shoreline to softer, variably graded fills inland — create foundation and subgrade conditions that demand careful verification before and during construction. Rhode Island's humid continental climate means freeze-thaw cycles that stress concrete placements from late autumn through early spring, and summer humidity that affects mix water demand and set time. Residential subdivisions, commercial corridors along the Route 2 and Route 4 corridors, and ongoing infrastructure work throughout the county all require materials testing prepared for third-party review. Our technicians, dispatched through the Boston regional hub, perform ASTM-compliant field and laboratory testing of concrete, soil, and aggregate — fresh concrete testing, cylinder breaks, Proctor compaction, nuclear density gauge testing, soil classification, and more — backed by a documented quality system and reporting built to support your project record.
Rhode Island's glacial geology commonly produces stratified drift soils with significant lateral variability, making representative sampling and proper ASTM D2487 classification critical for subgrade and fill acceptance decisions. Cold-weather concrete placements under Rhode Island's winter conditions warrant close attention to ACI 306 guidance, including monitoring of fresh concrete temperatures at point of discharge.
FAQ · Kent County
How do freeze-thaw conditions in Rhode Island affect when and how you test fresh concrete?
When ambient or concrete temperatures approach the thresholds defined in ACI 306R, our technicians record fresh concrete temperature per ASTM C1064 at every visit. That reading documents whether the mix met specification minimums at discharge — typically 55°F or as project-specified — and supports any cold-weather protection decisions the contractor and engineer of record need to make before finishing and curing begin.
Rhode Island DOT projects in Kent County often reference specific compaction acceptance criteria. Can you test to those requirements?
Yes. We establish the moisture-density relationship using ASTM D698 (Standard Proctor) or ASTM D1557 (Modified Proctor) as your specification requires, then perform field density testing with a nuclear gauge per ASTM D6938. Reports state the reference curve, test location, lift number, and percent compaction so your RIDOT submittal package has the documentation the agency expects.
What soil classification work can you provide for sites in Kent County with variable fill or unknown subgrade?
We perform laboratory soil classification per ASTM D2487 (USCS) and ASTM D422 for gradation, along with Atterberg limits testing per ASTM D4318. For projects working in areas of suspected variable or placed fill — not uncommon in Kent County's developed corridors — proper classification informs the geotechnical engineer's bearing capacity and compaction spec decisions before structural loads are applied.
How fast can a technician be on site in Kent County?
Kent 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 Kent County, RI?
Field work in Kent County is dispatched through the Boston, MA regional hub, about 49 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Kent County projects.
Are the technicians you send to Kent 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 Rhode Island agencies or owners require state-specific certifications, those are confirmed in the proposal.
