Scope
What we test in Manchester
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 Manchester
Manchester sits at the confluence of the Merrimack River valley and the foothills of southern New Hampshire, where glacially deposited soils — ranging from loose sandy outwash to dense till — can vary sharply across a single project site. Winter arrives early and lingers, compressing the window for concrete placement and soil compaction work and demanding close attention to cold-weather provisions. Meanwhile, the city's ongoing investment in mixed-use redevelopment, mill-building rehabilitation, and regional infrastructure keeps the pressure on project schedules. Construction materials testing ties all of it together: verifying that concrete gains the strength your design depends on, that fill compacts to the density your bearing calculations assume, and that aggregate meets the gradation your mix requires. Our certified technicians, dispatched through our Boston regional hub, perform ASTM-compliant field and laboratory testing of concrete, soil, and aggregate on a scheduled basis — generating clear, defensible reports that satisfy engineers, owners, and local authorities having jurisdiction.
Southern New Hampshire's glacial geology commonly produces variable subsurface conditions — including till, stratified outwash sands and gravels, and occasional ledge — that can require multiple soil classification and Proctor reference tests across a single site to establish reliable compaction control. The region's freeze-thaw cycle, with frost depths that can exceed four feet, makes concrete air-entrainment verification and cold-weather placement documentation especially important for structures expected to perform through New Hampshire winters.
FAQ · Manchester
New Hampshire winters often push concrete pours into near-freezing temperatures. What field tests confirm we're meeting cold-weather requirements?
During each concrete placement visit, the technician measures fresh concrete temperature per ASTM C1064, along with slump (ASTM C143), air content (ASTM C231), and unit weight (ASTM C138). Concrete temperature must satisfy ACI 306R cold-weather minimums at point of delivery and placement. Cylinders are cast per ASTM C31, with field curing records noted when ambient conditions trigger cold-weather precautions. This documentation supports both quality control and any contractor-of-record cold-weather plan.
Our Manchester site has highly variable fill from prior industrial use. How do you establish a reliable compaction standard when materials differ across the site?
Where fill composition varies, separate Proctor curves may be required for each distinct material type. Standard Proctor testing follows ASTM D698 and modified Proctor follows ASTM D1557; the applicable specification controls which method applies. Field density is then measured against the correct reference curve — by nuclear gauge per ASTM D6938 or sand cone per ASTM D1556 — ensuring compaction acceptance is tied to the actual material being placed rather than a single assumed curve.
How far in advance do I need to schedule a technician for a Manchester project, given that you dispatch from Boston?
Coverage for Manchester is dispatched through our Boston regional hub, approximately 48 miles away. We recommend scheduling at least 48 to 72 hours in advance for routine concrete cylinder breaks, compaction testing, or aggregate sampling visits. Project-based scheduling — where recurring visits are planned against a construction schedule — generally provides the most reliable coverage. Contact our dispatch team early in the project to set up a recurring service plan aligned to your milestone dates.
How fast can a technician be on site in Manchester?
Manchester 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 Manchester, NH?
Field work in Manchester 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 Manchester projects.
Are the technicians you send to Manchester 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.
