Scope
What we test in South 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.

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 South Burlington
South Burlington sits on glacially deposited soils — a mix of lacustrine clays, silts, and glacial till left behind by Lake Vermont — that can shift meaningfully with freeze-thaw cycling and seasonal moisture change. For developers and contractors working along the Williston Road corridor, near the airport, or on the expanding residential and mixed-use projects throughout Chittenden County, subsurface variability and Vermont's long frost season create real compaction, bearing, and concrete-placement challenges. Ignoring these conditions during construction invites costly rework and failed inspections. Our technicians dispatch to South Burlington to perform ASTM-compliant field and laboratory testing of concrete, aggregate, and soil — fresh concrete properties, cylinder breaks, gradation, Proctor compaction, nuclear density, soil classification, and corrosivity — supporting your QA documentation from grading through structural pour. Testing is coordinated through our Boston regional hub, and results are delivered in defensible written reports prepared for third-party review.
Vermont's deep frost penetration and extended shoulder seasons demand careful attention to subgrade moisture and density before placing pavement or foundations; glacially deposited lacustrine soils common to the Champlain Valley can exhibit low bearing capacity and high frost susceptibility, making Proctor and in-place density testing particularly consequential on South Burlington projects.
FAQ · South Burlington
How far in advance do I need to schedule a technician for a concrete pour in South Burlington?
Service to South Burlington is dispatched from our Boston regional hub, approximately 180 miles away, so advance scheduling is essential — ideally 48 to 72 hours before your pour. Early notice allows us to confirm technician availability and travel logistics. For fresh concrete testing, our technicians follow ASTM C172 for sampling and perform slump (ASTM C143), air content (ASTM C231), temperature, and unit weight (ASTM C138) at the point of placement.
Vermont winters are long. Can concrete cylinder curing and testing account for cold-weather placement conditions?
Yes. When ambient temperatures approach or fall below 40°F, ACI 306R cold-weather concreting practices become relevant, and documenting concrete temperature at placement per ASTM C1064 is a standard part of our field visit. Cylinders are field-cured in insulated boxes when required, then transported to the laboratory for standard curing and compression testing per ASTM C39 at the specified break ages.
The Champlain Valley is known for soft lacustrine soils. What testing do you perform to evaluate subgrade suitability before we place fill or pavement?
We perform soil classification per ASTM D2487 to characterize what you are working with, standard Proctor compaction testing per ASTM D698 or modified Proctor per ASTM D1557 to establish the compaction curve, and in-place density and moisture testing using a nuclear gauge per ASTM D6938. Together these give you the data needed to confirm subgrade preparation meets project specifications before committing to structural fill or pavement sections.
How fast can a technician be on site in South Burlington?
South 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 South Burlington, VT?
Field work in South Burlington is dispatched through the Boston, MA regional hub, about 180 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large South Burlington projects.
Are the technicians you send to South 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.
