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.

ASTM D698ASTM D1557ASTM D558ASTM D4718ASTM D6938

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.

ASTM G51ASTM G57ASTM G187

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 sits in the heart of Vermont's Green Mountains, where construction contends with glacially deposited soils, significant frost depth, and a compressed building season driven by harsh winters and spring thaw. Concrete placed in temperature extremes demands careful fresh-concrete monitoring; subgrade conditions ranging from compact glacial till to softer lacustrine deposits require thorough documentation before structures go up. Our firm dispatches certified field technicians from our Boston regional hub to Washington County on a scheduled and project-based basis, providing ASTM-compliant testing of concrete, aggregate, and soil from initial earthwork through structural topping. Every assignment is supported by a laboratory operating under a documented quality system, with reporting designed to satisfy Vermont Agency of Transportation requirements, IBC Chapter 17 special inspection programs, and private owner specifications alike. The result is test data your project team can rely on and defend.

Glacial soils common to Vermont's central plateau — including till, stratified drift, and frost-susceptible silts — can behave unpredictably under load and require careful classification and compaction verification. Vermont's deep frost penetration and wide seasonal temperature swings also make cold- and hot-weather concrete monitoring under ACI 305 and ACI 306 guidelines a routine necessity on regional projects.

FAQ · Washington County

How far in advance do I need to schedule a technician for a concrete pour in Washington County?

Coverage for Washington County is dispatched from our Boston regional hub, approximately 152 miles away, so advance scheduling is essential. We ask for a minimum of 48 to 72 hours' notice for planned pours. Early notice lets us confirm technician availability, review your mix design, and ensure we arrive in time for fresh-concrete testing per ASTM C172 sampling procedures before placement begins.

Vermont winters are long. Can your technicians perform concrete testing during cold-weather pours?

Yes. Our ACI-certified field technicians are trained to document concrete temperatures and verify that fresh-concrete and protection measures align with ACI 306R cold-weather concreting guidance. Fresh-concrete temperature is recorded per ASTM C1064, slump per ASTM C143, and air content per ASTM C231. These records create a defensible paper trail showing the concrete was placed and protected within specification tolerances.

Vermont soils can include frost-susceptible silts. What testing do you perform to evaluate subgrade suitability before we build?

We perform ASTM D2487 Unified Soil Classification to identify frost-susceptible materials such as ML or MH silts. Moisture-density relationships are established by ASTM D698 or D1557 Proctor testing, and field compaction is verified by nuclear gauge per ASTM D6938. Together these tests confirm whether the subgrade meets design bearing and compaction requirements before pavement, slabs, or structural fills are placed.

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, VT?

Field work in Washington County is dispatched through the Boston, MA regional hub, about 152 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 Vermont agencies or owners require state-specific certifications, those are confirmed in the proposal.
