Scope
What we test in Hillsborough 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 Hillsborough County
Construction in Hillsborough County, New Hampshire moves through a compressed building season. Frost penetrates deeply through the region's glacially derived soils — a mix of dense tills, stratified sands, and scattered ledge — and air temperatures that support fresh concrete placement are reliably limited to a defined window each year. Cold-weather concreting procedures, subgrade variability across a single site, and the demanding requirements of municipal, commercial, and residential development across communities like Manchester and Nashua make defensible materials testing a practical necessity, not a formality. Our firm dispatches certified field technicians to Hillsborough County projects through our Boston, MA regional hub, providing ASTM-compliant field and laboratory testing for concrete, aggregate, and soil. Testing is performed under a documented quality system, and reports are structured to satisfy engineer review, owner requirements, and public-agency submittals — giving your project a clear, traceable record at every phase.
Hillsborough County's glacially deposited soils — ranging from compact till to loose outwash sands — can vary significantly in bearing capacity and moisture sensitivity across short distances, making Proctor reference testing and in-place density verification (ASTM D1557, D6938) particularly important for earthwork QC. New Hampshire's winter and early-spring conditions also require documented cold-weather monitoring protocols to protect fresh concrete placements from freeze-related strength loss.
FAQ · Hillsborough County
New Hampshire winters can extend well into April — how does cold weather affect our concrete testing program?
When ambient or concrete temperatures fall near or below 40 °F, ACI 306R cold-weather concreting practices apply. Our technicians measure fresh concrete temperature per ASTM C1064 at every visit and document conditions that trigger protection requirements. Cylinder sets are initially cured in insulated field-cure boxes when temperatures demand it, and results are flagged in the report so the engineer of record can evaluate strength development against the exposure history.
Our Nashua site has variable fill of unknown origin under the slab area. What testing helps us characterize it before we build?
We perform soil classification under ASTM D2487 (Unified Soil Classification System) using grain-size analysis (ASTM D6913 or D422) and Atterberg limits (ASTM D4318) to identify material type and engineering behavior. If compaction of existing or imported fill is planned, we establish a Proctor moisture-density relationship (ASTM D698 or D1557) so in-place nuclear gauge readings (ASTM D6938) have a valid reference curve to work against.
How do you handle scheduling and dispatch for Hillsborough County projects, and how far in advance do I need to request a technician?
Coverage for Hillsborough County is dispatched through our Boston, MA regional hub, approximately 48 miles away. We ask for advance notice — typically at least the prior business day — to confirm technician availability and travel time against your pour or earthwork schedule. Concrete testing visits are coordinated around your batch-plant delivery window; we do not guarantee same-day dispatch, so early scheduling prevents gaps in your testing record.
How fast can a technician be on site in Hillsborough County?
Hillsborough 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 Hillsborough County, NH?
Field work in Hillsborough County is dispatched through the Boston, MA regional hub, about 48 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Hillsborough County projects.
Are the technicians you send to Hillsborough 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 New Hampshire agencies or owners require state-specific certifications, those are confirmed in the proposal.
