Scope
What we test in Burlington
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 Burlington
Burlington sits on the eastern shore of Lake Champlain, where cold, wet winters arrive early and linger, placing real demands on concrete work, earthwork scheduling, and the structural integrity of everything from mixed-use developments on the waterfront to institutional construction on the Hill. Vermont's glacially derived soils vary widely — from well-graded gravels near the lake terrace to frost-susceptible silts and clays — making reliable field and laboratory testing essential rather than optional. Our firm dispatches ACI- and NICET-certified field technicians to Burlington-area projects through our Boston regional hub, performing ASTM-compliant testing of concrete, aggregate, and soil from the first pour through final subgrade acceptance. Every test follows a documented quality system, and reports are written to support your submittal package, project documentation, and any special inspection plan required under IBC Chapter 17. Scheduling is arranged in advance to match your project timeline.
Vermont's glacial geology frequently produces variable subsurface conditions, including frost-susceptible fine-grained soils that require careful Proctor testing and density verification to meet compaction specifications. Burlington's cold-weather construction season also makes temperature monitoring and cold-weather concrete protection practices — governed by ACI 306 — a routine consideration on any project running into late fall or early spring.
FAQ · Burlington
Vermont winters can shut down earthwork for months. How do we handle soil compaction testing around Burlington's shoulder seasons?
Frozen or near-frozen soil cannot be reliably tested or compacted to specification, so scheduling density testing during active thaw and refreeze cycles requires judgment. We coordinate with your superintendent to time nuclear gauge or sand-cone density tests (ASTM D6938 or ASTM D1556) when soil temperature and moisture conditions are representative. Proctor reference curves established in the lab under ASTM D698 or D1557 remain the controlling benchmark regardless of season.
Our Burlington project has glacially deposited silts in the subgrade. What classification and compaction testing applies?
Glacial silts and silt-clay mixtures common to the Champlain Valley are classified by grain-size analysis (ASTM D6913) and Atterberg limits (ASTM D4318), then assigned a USCS group symbol per ASTM D2487. Because ML and MH soils are frost-susceptible and sensitive to moisture, Proctor testing (ASTM D698 or D1557) and precise field density verification are particularly important before structural fill or pavement sections are placed above them.
How far in advance do we need to schedule a concrete testing visit on a Burlington project?
Coverage for Burlington is dispatched through our Boston regional hub, approximately 180 miles away, so advance scheduling is necessary — we do not offer same-day dispatch to this location. Contact us as soon as your pour date is confirmed to reserve a technician. Our field staff performs slump (ASTM C143), air content (ASTM C231), temperature, unit weight (ASTM C138), and cylinder fabrication (ASTM C31) per your project specification.
How fast can a technician be on site in Burlington?
Burlington 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 Burlington, VT?
Field work in Burlington is dispatched through the Boston, MA regional hub, about 182 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Burlington projects.
Are the technicians you send to Burlington 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.
