A damp building creates unhealthy conditions for occupants and also gives rise to the breeding of mosquitoes.
Corrosion of metals used in the construction of the building may take place.
The unsightly patches are formed on the ceilings and walls surfaces.
The decay of timber takes place rapidly due to dry-rot in a damp atmosphere.
It results in 1:1 softening and crumbling of plaster.
It promotes the growth of termites.
The walls may cause efflorescence, which may result in the disintegration of stones, bricks, tiles, etc. and the strength of the wall is then reduced.
The materials used as floor coverings are seriously damaged.
The electric fittings deteriorate, and it may lead to a danger of short-circuiting.
Unhealthy living for the occupants prevails in a damp building.
Efflorescence on building surfaces takes place, causing the disintegration of the bricks, stones, tiles, etc. and thus useful life of a building is being lost.
It causes bleaching of paint, which results in the formation of coloured patches on wall and ceiling surfaces.
It results in softening and crumbling of plaster.
Timber, when it comes in contact with water, gets deteriorated due to warping, buckling, and rolling.
Dampness promotes the growth of termites.
The surface of the wall is affected patches. Are seen on walls. The point false off, and colours get faded.
The building elements made up of timer distorted in their dimensions. The timber may decay.
Rising of moisture from the ground: The subsoil moisture, present below the ground level, rises through the foundation beds due to capillary action.
From the external walls: If the faces of walls are subject to heavy showers of rain, or if they are not being protected properly, the water will percolate in and causes dampness.
Top of walls: Parapet and compound walls also become a source of dampness as the rain water descends down the wall and causes dampness.
Condensation: When warm humid air is cooled, condensation takes place. Due to condensation, moisture is deposited on the walls, floors and ceilings and causes dampness.
Leaks: Water leaks from roofs, plumbing systems, windows, or other building components can introduce moisture into the building, leading to dampness.
Condensation: Condensation occurs when warm, moist air comes into contact with cooler surfaces, causing water droplets to form. Inadequate ventilation and insulation can contribute to condensation on walls, windows, or ceilings.
Rising damp: Rising dampness happens when groundwater travels upwards through porous materials like masonry or concrete, resulting in moisture penetration in walls, floors, or foundations. This can occur due to the absence of a damp-proof course or failure in an existing damp-proofing system.
