What is Dampproofing?

Damp proofing walls is the process of preventing moisture from the ground from entering the walls and damaging the entire structure. More importantly, it is a process that leads to the diffusion of moisture content into the houses through walls, floors, roofs, etc.

Properties that are not safeguarded with proper damp proofing solutions are often damaged due to the excess moisture rising from the ground. The moisture can then affect the plaster, and the cosmetic appearance of the structure. Thus, damp proofing walls and roofs is an important part of the construction process.

So, if your dream home is in the construction phase, or you are planning to renovate your space, keep reading further to know why it is necessary to invest in damp proofing solutions:


Why is Dampproofing Necessary?

When a house is built from materials like bricks and concrete, it is always at a risk of water dampness. This is why you will find water problems like dampness and mildew on the lowest levels of buildings and masonry houses.

Therefore, look for professional damp proofing wall solution that can keep your building moisture-free, and reduce the rate of water absorption to avoid damage.

Now that you know why damp proofing is important, let’s quickly understand the root causes of dampness in the buildings:

  1. Excess moisture
  2. Use of poor construction materials
  3. Inadequate gutters
  4. Climatic conditions
  5. Soil drainage problems
  6. Entrapped moisture during concreting
  7. Moisture ingress from the ground to the walls
  8. Leaking pipes
  9. Condensation problems

With causes of damp proofing revealed, let’s now focus on understanding the best dampproofing methods below:

What are the best Dampproofing Methods?

Applying or spraying a coat of damp proofing solution on the external walls is an effective way. It acts as a barrier that helps prevent rising dampness on the house exteriors.  Besides this method, there are other methods of damp proofing (as mentioned below) to treat damp walls internally:

· Joint Filler and Liquid Wrap

This is the one of the common methods of damp proofing. All you require is a liquid wrap made from a polymer and apply it over the damp or moist areas. But before the liquid wrap is applied, use a waterproof joint filler to close any cracks and holes.

· Asian Paints Dampproof Solution

Formulated with PU hybrid polymers and reinforcing acrylic fibres, Asian Paint’s SmartCare Dampproof Ultra is a great way to prevent ultimate dampness.

· Flashing Materials

You can damp proof your house by investing in flashing materials, such as damp-proof membranes. These membranes are impermeable to water, making it easy to prevent it from passing through the walls into your building. Yes, so you can prime your walls with paint for damp walls interior, and then apply a damp proof membrane.

Asian Paint’s SmartCare Damp proof is a glass fibre reinforced elastomeric liquid-applied waterproofing membrane, which upon curing, forms a thick, seamless membrane.

· Damp proofing creams or rods

Damp proofing rods are made of silane/siloxane polymer with water-repellent qualities. Once they are installed, they can prevent the dampness from travelling up the walls by capillary action. You can even use damp proof paint for roof or paint for damp walls interior, for ultimate protection.

Causes of Dampness in Walls 

Here are the most common causes of dampness in walls:

  1. Poor ventilation is one of the major causes of dampness as a lot of moisture is generated while washing clothes, cooking, or drying clothes inside your house.
  2. Dampness can penetrate the walls through leaking roof tiles or leakages from an adjacent bathroom.
  3. Water from dripping plumbing lines of the exteriors or interiors can result in damp walls.
  4. Rising damp is a very common problem in older homes especially in houses where a damp proof course has not been used to create a barrier between the soil and the foundation of the building.

Now that you know what dampproofing is, its importance and causes of dampness in walls, let’s proceed further to understand the difference between waterproofing and damp proofing:
