Dampness is the process of Water rising from the ground level to the superstructure of the building. Black and brown color is visualized on the wall due to the dampness. There is a problem called Dampness that has a negative impact on the looks, strength, structure, and age of our house. Which is very necessary to solve. Today we will discuss this topic. Stay tuned till the end.

What is the Dampness of the Wall?

Dampness is the presence of moisture. It is the building may occur due to bad design, faulty construction, and the use of weak quality materials. It creates unhygienic conditions of living.

What is the Dampness of the Wall? Causes, Sources, Effects, and Method of Damproof.

Causes and sources of dampness

  • It is rising through the foundation wall due to capillary action.
  • Splashing rainwater hitting the wall surface.
  • Penetration of rainwater protects the top of walls in the structural element.
  • In the case of a sloped roof, rainwater may percolate through the defective roof covering.
  • On condensation, the moisture present in the atmosphere gets deposited on the component of the wall which causes dampness.
  • Improperly constructed roof slaps, improper rainwater pipe connection
  • Dampness may be due to leakage of pipe fitting of bathrooms, and kitchen.

Effects of dampness

I have mentioned some effects of the dampness that occurs wall is to be unhygienic. Majorly these are effects of dampness.

  • Removing plaster and paints from the wall.
  • Feedout putting and color from the wall.
  • Presence of fungi and dark patches in the wall surface.
  • Reduce the strength of the Masonry wall.
  • Damage of wood laying on wall and floor.
  • Lead to the corrosion of metals.
  • Deteriorate electrical fitting
  • It promotes the growth of termites.
  • Creates unhygienic conditions for living.

Method of Damp proof course

  • Provide a waterproof membrane on the wall.
  • Applying chemical coating on the damp surface.
  • Provide an extra layer of membrane during the construction of a wall between the Plinth beam and the superstructure wall. This layer helps to disconnect water contact from base to wall.
  • Provide DPC Level using Bitumin sheet, cement, concrete, and polythene sheets.
  • The D.P.C. should Cover the full thickness of the walls.
  • When horizontal DPC is continued on the vertical face a cement concrete-filled 75 mm radius is provided.

Surface treatment for the dampness of the Wall 

Moisture finds its way through the pores of material used in finishing. The walls plaster with cement, lime, and sand mixed in the proportion of 1:1:6 is found to serve the purpose of preventing dampness in the hall due to rain effectively.

What is the Dampness of the Wall? Causes, Sources, Effects, and Method of Damproof.

Integral damp proofing

This consists of adding certain waterproofing compounds to the concrete mix to increase impermeability. Such compounds are available in marker in liquid or powder form. In general, one kg of waterproofing compound is added to one bag of cement.

Hunting of Dampness of Wall 

This consists of depositing an imperious layer of rich cement mortar over the surface to waterproof the operation carried with the use of a cement gun.

The surface is to be treated thoroughly cleaned and wanted properly. Cement sand in proportion of 1:S is fed in the machine and this mixture is finally shot on the prepared surface under a pressure of 2 to 3 kg/cm^3.

Ideal requirement of material used for DPC

Ideal damp-proofing materials should have the following characteristics

  1. The materials should be perfectly imperious.
  2. The material should be durable.
  3. The material should be strong and capable of resisting supper imposed load on it.
  4. Should be flexible so that it can accommodate the structural movement without any friction.
  5. The material should be economical.

Material use in the DPC

  • Hot bitumen
  • Plastic sheets
  • Cement Concrete
  • Stones such as granites, Marble, etc.
  • Metal sheets.
