How to Control Moisture inside wall


Reason:
Masonry, including concrete, is porous and moisture is able to travel through it. As moisture passes through masonry, for example a foundation wall, it encounters and dissolves salt crystals. When this moisture reaches the inner surface of the foundation wall the moisture evaporates, leaving behind the white salt crystals.

Sources:
Moisture from general home activities such as cooking, bathing, or washing dishes and  clothes.
Humidity
Exterior moisture and water vapor
Construction moisture--from building materials.
Leaking Roof
Exterior Wall should be plastered properly.


Solutions:
Ventilation to keep indoor humidity at a reasonable level
Elimination of air leakage into wall cavities
Ventilation of crawl spaces to prevent soil moisture from entering the building

We use Moisture Control Techniques like control water, air movement, vapor diffusion, condensation as per condition of wall
