Scope
What we test in Franklin 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 Franklin County
Franklin County sits in Vermont's Champlain Valley and Northeast Kingdom transition zone, where glacially deposited soils — silts, clays, and mixed till — create real variability across a single project site. Short construction seasons, hard freezes that can arrive well before calendar winter, and spring frost heave all put pressure on concrete placement schedules and compaction timelines. For developers building mixed-use or light industrial projects in St. Albans or Swanton, and for contractors working on municipal infrastructure across the county, materials testing is not a checkbox — it is what keeps a structure performing through decades of Vermont freeze-thaw cycles. Our certified technicians dispatch to Franklin County from our Boston regional hub, providing scheduled and project-based field testing of concrete, soil, and aggregate alongside laboratory analysis. Every result is documented under our quality system and delivered in reports prepared for third-party review.
Glacially derived fine-grained soils common to the Champlain lowlands in Franklin County can exhibit moisture sensitivity and low bearing capacity, making Proctor moisture-density relationships and in-place compaction verification especially important before placing structural fill or pavement sections. Vermont's extended frost season also compresses workable concrete placement windows, placing added importance on fresh concrete temperature monitoring and cold-weather curing documentation in accordance with ACI 306.
FAQ · Franklin County
Vermont winters come early — what concrete temperature documentation do you provide during cold-weather placements?
Technicians record fresh concrete temperature at point of discharge per ASTM C1064 on every field visit. When ambient conditions trigger ACI 306 cold-weather thresholds, those temperature readings become part of the formal test record, giving your superintendent and the engineer of record documentation that placement complied with the specification's cold-weather concrete requirements.
Our site in Franklin County has variable fill and what looks like marine clay in one corner — how do you handle soil classification across a site with that kind of variability?
Technicians collect representative samples from each distinct material zone and run ASTM D2487 Unified Soil Classification testing in the laboratory. Where corrosivity is a concern for buried utilities or reinforcement, we add pH, resistivity, chloride, and sulfate testing per ASTM G51 and ASTM D4972. Classification data from each zone is reported separately so the geotechnical engineer can respond to the actual site conditions.
We're compacting structural fill under a slab-on-grade in Swanton and the spec calls for 95 percent of modified Proctor — how do you establish and verify that?
We first run ASTM D1557 modified Proctor in the laboratory to establish the maximum dry density and optimum moisture for the fill material. Field compaction is then verified using a nuclear density gauge per ASTM D6938, comparing in-place density and moisture to the laboratory standard. Each test location, depth, and result is logged and reported so the project record documents spec conformance lift by lift.
How fast can a technician be on site in Franklin County?
Franklin 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 Franklin County, VT?
Field work in Franklin County is dispatched through the Boston, MA regional hub, about 197 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Franklin County projects.
Are the technicians you send to Franklin 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.
