Perched along the unforgiving coast, a historic hotel’s structural backbone was showing alarming signs of wear—cracking concrete, corroding steel, and deflections that signaled something deeper than surface damage. With its plaza-level slab exposed to decades of salt-laden air and tidal forces, the risks of collapse or costly failure loomed large. Concrete Science® was brought in to uncover the truth beneath the surface and engineer a path forward. What they discovered would reshape the hotel's future and reveal the hidden toll of coastal exposure on reinforced concrete.
