Chapter 23 Damp Proofing

23.1 SOURCES OF DAMPNESS

Dampness in buildings is generally due to one or more of the following reasons:

Faulty design of structure
Faulty construction or poor workmanship
Use of poor materials in construction

These causes give rise to an easy access to moisture to enter the building from different points, such as rising of moisture from the ground and rain penetration through walls, roofs and floors. The moisture entering the building from the foundation and roofs travels in different directions further under the effects of capillary action and gravity, respectively. The entry of water and its movements, in different parts of the building, are positively due to one or more of the causes listed above. The various ...
