Moisture Issues (Natural Stone)

Floor Detective® Claims and Conditions Guide

Summary

Moisture movement is one of the most common contributors to staining, mineral deposits, and deterioration in natural stone installations. Water may enter stone assemblies through surface exposure, capillary migration, vapor movement from substrates, or installation materials. As moisture travels through the pore structure of stone and associated setting materials it may transport dissolved minerals, salts, and contaminants. When moisture later evaporates, these materials can concentrate within or on the stone surface, producing conditions such as efflorescence, mineral crusting, iron staining, or surface deterioration. Evaluation of moisture-related conditions focuses on identifying moisture sources, migration pathways, and
