Moisture is the hygroscopic or gravitational presence of moisture. Moisture leads to unhygienic conditions besides reducing the strength of structural components of the building.
Moisture causes the following harmful effects.
- Moisture is responsible for the breeding of mosquitoes and creates unhealthy living conditions.
- Due to dampness, moisture travels through walls and roofs and forms unsightly patches and affects the aesthetics of the building.
- In the case of lime plaster, the travel of moisture causes the plaster to soften and collapse.
- Swelling occurs due to moisture in the wall and sometimes moisture is responsible for dissolution of bricks, stones, tiles etc.
- Wall decorations (like paintings) get damaged due to moisture.
- When moisture enters through the floor, the floor loosens due to a decrease in adhesion.
- Wood fittings (e.g. doors, windows, almirahs) when in contact with damp walls or floors, tend to wear out, causing the wood to bend, buckle, dry out, etc.
- Moisture in a building can be very dangerous if any type of electrical fitting comes into contact with it.
- Floor coverings are damaged. Therefore no floor coverings should be used on damp floors.
- Moisture promotes and accelerates the growth of termites.
- Moisture causes germs of dangerous diseases like tuberculosis, neuralgia, arthritis etc.
- Metal fittings tend to rust due to moisture.
