Forensic Engineering in Columbia, SC
Columbia's distress cases divide along the fall line like everything else here: Piedmont-side failures of wet-placed residual fills and mixed bearing, and sand-side failures where loose zones, erosion, and washout undermine slabs and pavements, plus the concrete and construction questions any capital city generates. The investigation runs on evidence: elevation surveys mapping movement, borings and sampling establishing density profiles and material conditions beneath the distress, cores per ASTM C42, and petrographic examination per ASTM C856 where the concrete is in question. Erosion-driven cases add drainage-history reconstruction, because in sand country water leaves a legible trail. Chain of custody is maintained, with licensed engineers engaged in South Carolina for evaluation and testimony.
Subsurface erosion, fines washing through sandy profiles along utility trenches and drainage paths, is a signature Columbia mechanism, and it leaves boring and density evidence that distinguishes it cleanly from consolidation settlement.

FAQ · Columbia
The slab dropped along one line. What does that pattern suggest?
Linear settlement follows linear causes: a utility trench, a drainage path, an eroded zone. In sandy ground, washout along a leaking line is a leading hypothesis, and borings on and off the line, plus the utility's own history, test it directly.
Can loose sand under an older building be proven as original?
Often. Density profiles from standard sampling distinguish never-densified sand from later disturbance, and construction-era records, where they exist, complete the picture. The sand keeps honest books.
