Forensic Engineering in Raleigh, NC

Triangle distress cases sort by which side of the basin boundary they sit on. West of it, the docket looks almost Texan: slabs and pavements moving as Triassic clays cycle moisture, distress that Piedmont-calibrated design never anticipated. East of it, the failures are Piedmont classics, wet-placed micaceous fill, mixed bearing across saprolite and PWR. The investigation distinguishes them with evidence: elevation surveys mapping the movement's shape, borings and sampling establishing the material and its moisture state beneath the distress, cores per ASTM C42, and petrographic examination per ASTM C856 where concrete questions arise. Chain of custody is maintained, with licensed engineers engaged in North Carolina for evaluation and testimony.

Basin-clay movement cases around Durham and western Wake County frequently trace to designs that never tested for swell; the absence of swell data in the original investigation is itself a finding worth establishing.
