What are the effects of prolonged exposure to saltwater on stone integrity?
Prolonged exposure to saltwater can significantly compromise the integrity of stone materials through multiple mechanisms. Saltwater accelerates chemical weathering by dissolving soluble minerals within the stone, leading to internal weakening. Crystallization of salt within pores creates pressure, causing cracks and surface flaking. Marine environments also promote biological growth, such as algae and lichens, which further degrade stone surfaces. Over time, these processes result in reduced structural stability, increased porosity, and visible deterioration. Stones like limestone and sandstone are particularly vulnerable due to their high permeability. Preventive measures, such as sealants or regular maintenance, are essential for preserving stone structures in coastal areas.
