What are the effects of dampness
The building materials such as bricks, timber, concrete, etc., have a moisture content that is not harmful under normal circumstances.
The rise in moisture content of these materials beyond a certain level from where it become visible or when it causes deterioration leads to real dampness.
In absolute terms, the moisture content of different materials may be the same. However, the acceptable limit differs from material to material.
For instance, the presence of 10 percent by weight of water in timber is not harmful. But the same level could saturate a brick or cause deterioration of plaster.
The structure is badly affected by dampness. The prominent effects of dampness are as follows:
(1) A damp building gives rise to the breeding of mosquitoes and creates unhealthy conditions for those occupy it. भरता, अधिकार
(2) Metals used in the construction of the building corroded.
(3) The unsightly patches are formed on the wall surfaces and ceilings.

(7) The materials used as floor coverings are seriously damaged.
(8) It promotes and accelerates the growth of termites.
(9) It results in softening and crumbling of the plaster.
(10) The materials used for wall decoration are damaged and it leads to difficult and costly repairs.
(11)The continuous presence of moisture in the walls may cause efflorescence which may disintegrate stones, bricks, tiles, etc., and the strength of the wall is then reduced.
(12) The floorings get loosened because of a reduction in the adhesion when moisture enters
(13)The dampness combined with warmth and darkness breeds germs of dangerous diseases such as tuberculosis, rheumatism, etc. and the occupants may also become asthmatic.
