Scope
What we test in Nashua
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 Nashua
Nashua sits at the convergence of two river valleys, and the soils beneath its expanding commercial corridors, mixed-use districts, and residential subdivisions reflect that geography — variable glacially deposited materials that demand verified compaction and classification data before a foundation or pavement section performs as designed. New Hampshire's climate adds another layer of complexity: freeze-thaw cycles that stress concrete placements in shoulder seasons, and temperature windows that compress the reliable construction calendar. These conditions make defensible, documented materials testing a practical necessity, not a compliance formality. Our firm covers Nashua through scheduled and project-based dispatch from our Boston-area regional hub, putting ACI- and NICET-certified field technicians on your site to perform ASTM-compliant concrete, aggregate, and soil testing. Results are delivered in structured reports built to support your inspections, specifications, and owner submittals — giving contractors, developers, and engineers the data they need to keep work moving and decisions grounded.
Glacial till and glaciofluvial outwash deposits are common across southern New Hampshire, meaning subgrade conditions can shift within a single project footprint and Proctor-referenced compaction verification matters across fill zones. Cold-weather concrete placement under ACI 306 conditions is a regular reality in Nashua from late fall through early spring, making fresh concrete temperature monitoring a routine part of field testing visits.
FAQ · Nashua
What soil classification testing do you perform, and why does it matter for Nashua projects?
We perform grain-size analysis per ASTM D6913, Atterberg limits per ASTM D4318, and USCS classification per ASTM D2487. In an area characterized by glacially deposited soils — ranging from dense till to loose outwash sands — classification testing identifies whether subgrade and fill materials meet specification before compaction work begins, preventing costly rework when variable conditions appear mid-project.
How do you handle concrete testing during New Hampshire's cold-weather season?
Field technicians measure fresh concrete temperature at point of discharge per ASTM C1064 on every visit. When temperatures indicate ACI 306 cold-weather conditions, recorded data supports the contractor's protection plan and provides the owner documentation that placement temperatures were within specification. Cylinder sets cast during cold weather are protected and transported to maintain curing integrity before laboratory break testing per ASTM C39.
What compaction testing method is used for structural fill and pavement subbase in Nashua?
Nuclear density gauge testing per ASTM D6938 is the standard field method for rapid, project-paced compaction verification, referenced against a laboratory-established moisture-density relationship (Proctor) per ASTM D698 or D1557 depending on your specification. For projects with restrictions on nuclear gauge use, sand cone testing per ASTM D1556 is available. The applicable Proctor method is confirmed against your project specifications before mobilization.
How fast can a technician be on site in Nashua?
Nashua 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 Nashua, NH?
Field work in Nashua is dispatched through the Boston, MA regional hub, about 35 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Nashua projects.
Are the technicians you send to Nashua 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.
