Vapour diffusion is the process of moisture passing through breathable or permeable constructing materials, like drywall and insulation.

Many homeowners see this moisture and believe they're experiencing basement wall leakage, when in reality the amassed moisture is from condensation. In a 1-inch rain, 1,250 gallons of water fall on the roof of a 2,000-sq.-foot house. Without proper grading, gutters and downspouts, a few of this water flows into the basement.

The damp meters they use must be banned as they're nearly completely ineffective for the job except you might be extremely expert in their use. They measure electrical conductivity and salts will give a false high studying. If it's an old house and the hearth burnt fossil gas then these include salts that finally leach by way of the brickwork into the plaster.

Air Brick Problem

The confusion arises as a result of air often holds quite a lot of moisture within the vapour form. When this air strikes from location to location because of an air strain difference, the vapour moves with it.
