← HistoryWhich failure can undermine buildings using 'pietra dura'?
A)Foundation settling from differential compaction✓
B)Porous stone cracking from freeze-thaw
C)Metal tie corrosion expanding masonry
D)Efflorescence weakening joint mortar
💡 Explanation
Differential compaction leads to localized foundation settling because inconsistent soil density allows faster compaction, resulting in structural stress concentration rather than evenly distributed load; therefore, 'pietra dura' inlays crack rather than remain aligned if the foundation shifts.
