Forensic Engineering in Rockingham County, NH

Chain-of-custody documentation creates a continuous, verifiable record of who collected each sample, when, under what conditions, and how it was transported and stored. For litigation or insurance proceedings, this record establishes that evidence has not been altered or contaminated between field collection and laboratory analysis. Without it, opposing parties can challenge the integrity of test results regardless of their technical merit.

Frozen ground can restrict probe sampling and some coring operations, and snow or ice cover may obscure pavement or slab surface conditions relevant to the investigation scope. Scheduling during accessible conditions is preferable when feasible. If emergency access is needed during winter, our dispatch team coordinates equipment and approach accordingly. Freeze-thaw itself is often a subject of the investigation, particularly for concrete scaling or pavement distress cases.

Petrographic examination of hardened concrete cores follows ASTM C856, Standard Practice for Petrographic Examination of Hardened Concrete. This analysis can identify alkali-silica reactivity, carbonation depth, air-void distribution, paste quality, aggregate characteristics, and physical or chemical deterioration consistent with freeze-thaw damage, sulfate attack, or other mechanisms relevant to distress patterns observed at the Rockingham County site.
