Efflorescence Can be PreventedWhile water seepage from the inside can be resolved by diverting the water, the problem of efflorescence and other mineral build-ups related to moisture may not be totally solved.
Is efflorescence a problem?
Efflorescence alone does not pose a major problem, but it can be an indication of moisture intrusion, which may compromise the structural material. Building materials, such as concrete, wood, brick and stone, are porous materials. Porous materials can absorb or wick water by a process called capillary action.How much does it cost to remove efflorescence?
