Local conditions
Forensic conditions in Hillsborough County
New Hampshire's freeze-thaw cycle is among the most demanding in the northeastern United States. Hillsborough County structures — from Manchester's urban commercial corridors to suburban residential developments across the county — face repeated seasonal stress on concrete, foundations, and pavements. When distress appears, the cause is rarely obvious: poor mix design, inadequate air entrainment, subgrade settlement, construction defects, and deferred maintenance can produce similar visible symptoms. Our firm provides structured forensic investigation services to help contractors, developers, and engineers move from observation to defensible conclusion. We coordinate systematic evidence collection — including concrete coring per ASTM C42, representative sampling, and chain-of-custody laboratory analysis — and engage licensed professional engineers to deliver written evaluations and, where required, expert opinion and testimony. Coverage for Hillsborough County is dispatched through our Boston, MA regional hub.
Hillsborough County soils vary across the region and can include glacially deposited till and granular outwash material, conditions that influence foundation bearing behavior and drainage patterns relevant to settlement investigations. New Hampshire's extended freeze-thaw season makes air-void system performance in concrete a frequent subject of forensic inquiry, particularly for flatwork and pavement in exposed conditions.
FAQ · Hillsborough County
What does your firm actually do on-site during a forensic investigation in Hillsborough County — what should we expect the visit to look like?
Field work typically includes systematic visual documentation, crack mapping, and the collection of physical samples. Concrete cores are extracted per ASTM C42 to obtain specimens for compressive strength, petrographic examination (ASTM C856), or chloride profiling (ASTM C1202) as conditions warrant. All samples are logged, labeled, and transported under documented chain-of-custody procedures before laboratory analysis begins.
How does the freeze-thaw climate in New Hampshire factor into a concrete distress investigation?
Repeated freeze-thaw cycling is a primary distress mechanism for concrete in Hillsborough County. Investigation often focuses on the air-void system, assessed through petrographic examination per ASTM C856, to determine whether adequate entrained air was present at placement. Scaling, D-cracking, and delamination patterns observed on flatwork and pavement surfaces are documented and correlated against available mix design and placement records.
Our project involves pavement or flatwork that settled unevenly — can you investigate the subgrade as well as the concrete itself?
Yes. Settlement investigations address both the concrete element and the supporting material. Sampling of subgrade soils may be conducted alongside concrete coring to evaluate compaction, moisture conditions, and whether frost-susceptible soils contributed to heave or subsidence. Laboratory testing on soil samples can include gradation (ASTM D6913) and Atterberg limits (ASTM D4318), providing data to support the licensed engineer's evaluation.
