Scope
What we test in Rockingham 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 Rockingham County
Rockingham County sits where southern New Hampshire meets the seacoast, a region pushing through sustained residential subdivision, commercial corridor redevelopment, and infrastructure work along the I-95 and Route 101 corridors. Construction here faces real material challenges: glacially deposited soils that shift from dense till to loose outwash sand within a single site, freeze-thaw cycles that demand disciplined concrete placement and curing through a long frost season, and owners and agencies that increasingly require documented special inspection programs under IBC Chapter 17. Our firm dispatches certified technicians from the Boston regional hub to provide ASTM-compliant field and laboratory testing of concrete, aggregate, and soil. Fresh concrete testing, cylinder breaks, Proctor compaction, nuclear density, aggregate gradation, and soil classification are all performed by ACI- and NICET-certified technicians under a documented quality system, delivering reports prepared for third-party review.
Glacial till and stratified-drift soils common across Rockingham County can vary significantly in bearing capacity and moisture sensitivity over short distances, making soil classification and compaction verification — per ASTM D698, D1557, and D6938 — especially important before footings and earthwork are signed off. New Hampshire's frost depth requirements and the region's extended cold-weather window also place real demands on concrete placement timing, mix proportioning, and protection practices that field testing must document accurately.
FAQ · Rockingham County
Our site in Rockingham County has variable fill — some areas look like old outwash, others like dense till. What testing helps us characterize it before we commit to a foundation design?
Soil classification under ASTM D2487 (Unified Soil Classification System) combined with Proctor moisture-density testing per ASTM D698 or D1557 gives the geotechnical team what it needs to differentiate material behavior across the site. Where fill origin is uncertain, ASTM D2216 moisture content sampling and visual-manual classification in the field flag problem zones before foundation decisions are locked in.
We're pouring concrete slabs in October. What additional testing or documentation do we need for cold-weather work in New Hampshire?
ACI 306R defines cold-weather concrete practices; field documentation should include fresh concrete temperature per ASTM C1064 at point of delivery and placement, along with slump (ASTM C143) and air content (ASTM C231). When ambient or forecast temperatures approach 40°F, protection and heating logs should accompany cylinder records so the project file demonstrates mix and curing conditions were maintained through the protection period.
The town building department is asking for a special inspection program. How does materials testing fit into that requirement for a commercial project in Rockingham County?
IBC Chapter 17 requires a Statement of Special Inspections listing the materials and operations subject to continuous or periodic inspection, including concrete, fill, and masonry. Our technicians perform the field and laboratory tests that generate the inspection records — cylinder breaks per ASTM C39, compaction per ASTM D6938 — that feed into the special inspection reports submitted to the authority having jurisdiction at project completion.
How fast can a technician be on site in Rockingham County?
Rockingham 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 Rockingham County, NH?
Field work in Rockingham County is dispatched through the Boston, MA regional hub, about 43 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Rockingham County projects.
Are the technicians you send to Rockingham 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.
