Scope
What we test in Washington 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 Washington County
Washington County, RI presents a distinctive mix of coastal development, rural residential growth, and infrastructure work across towns like Westerly, South Kingstown, and Narragansett. Construction here contends with glacially deposited soils that can vary sharply over short distances — ranging from dense gravels and sands to softer organic or silty layers near coastal lowlands and pond edges. Concrete work faces real seasonal pressure: Rhode Island's freeze-thaw cycle demands close attention to placement temperatures, air entrainment, and curing procedures from late autumn through early spring. Our firm dispatches certified field technicians from our Boston regional hub to provide ASTM-compliant testing of concrete, aggregate, and soil throughout Washington County. Fresh concrete testing, compressive strength cylinders, aggregate gradation, Proctor compaction, nuclear density, and soil classification are performed under a documented quality system and reported with the documentation your project specifications and local agency submissions require.
Glacially influenced soils across Washington County can include stratified sands and gravels alongside pockets of organic or fine-grained material, making soil classification and Proctor testing particularly important before earthwork acceptance. Rhode Island's coastal climate introduces freeze-thaw cycling that affects both compaction timing in late-season grading work and concrete air-content requirements throughout the colder months.
FAQ · Washington County
My project is near the Ninigret or Point Judith area — should I expect soil variability to affect my earthwork testing plan?
Coastal and near-pond areas in Washington County can exhibit significant lateral variability in soil type and density, including organic lenses and fine-grained deposits. ASTM D2487 classification and ASTM D698 or D1557 Proctor testing should be performed on representative samples from each distinct soil unit encountered, not assumed uniform across the site. Your geotechnical engineer of record should define acceptance criteria by soil zone.
How does Rhode Island's freeze-thaw climate affect concrete testing requirements on a Washington County project?
Rhode Island's climate subjects concrete to repeated freeze-thaw cycles, making air-void content critical. ASTM C231 pressure meter testing for air content is standard for every load placed in exposed conditions. ACI 318 and ACI 306R set minimum air content and temperature requirements for cold-weather placements. Our technicians document fresh concrete temperature alongside slump (ASTM C143), air, and unit weight (ASTM C138) on every field visit.
What soil corrosivity tests are available, and why would a project in Washington County need them?
Coastal proximity and certain glacial soil chemistries can elevate corrosion risk for buried metallic utilities, anchors, and reinforcement. We perform soil resistivity, pH, soluble sulfate, and chloride testing per applicable ASTM standards. Results support material selection decisions for buried infrastructure and are often required when MSE wall backfill, ductile-iron pipe, or galvanized elements are specified — a relevant consideration near Washington County's coastal and tidal corridors.
How fast can a technician be on site in Washington County?
Washington 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 Washington County, RI?
Field work in Washington County is dispatched through the Boston, MA regional hub, about 68 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Washington County projects.
Are the technicians you send to Washington 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.
