Roof Waterproofing and Its Main Purpose

In simple terms, waterproofing is a process through which we protect the building structure from water. Multiple sources can take water from the roof, including rain, kitchen or bathroom water pipelines, etc. The water from these sources can cause leakage or seepage in the walls or roofs, ultimately leading to serious consequences. So to protect the building structure from water-related issues like seepage and leakage, we use roof waterproofing services.

Major Sources of Water

Let’s discuss some of the primary water sources and their effects on the building structure:

Natural Sources

Rainwater is one of the prominent reasons producing problems like seepage and leakage. Especially houses where it rains frequently are more vulnerable to these problems. Sometimes the roof floor is not perfectly designed, and water stays there, leading to seepage in the walls. Moreover, some areas are more prone to natural causes, like waterproofing in Lahore is quite important due to severe rains, especially during the monsoon.

Unnatural Sources

Some people use their roofs for domestic purposes, like washing clothes, which also causes the roof floor to absorb the water, resulting in seepage on the walls. Moreover, sometimes the water drainage pipelines in the walls of houses also get leaked, resulting in seepage. So in such situations, waterproofing treatment of the roof becomes imperative. Without this, the issue gets intensified and gives rise to many problems.

Methods of Effective Waterproofing

There are two methods of waterproofing roofs which we will discuss here in detail:

Conventional Method or Mud Tile Waterproofing

There are multiple steps involved in the conventional roof treatment solution. Let’s discuss it step by step:

  1. First of all, the roof is cleaned.
  2. After that, a layer of coal tar mixed with kerosene oil (known as Primer) is applied to the roof’s surface.
  3. Now two coats of coal tar are applied to the roof, and in this step, 10 Kg of coal tar is used per square foot.
  4. In the fourth step, a polythene layer is applied to it.
  5. Now a 3-inch layer of clay is put on, after which the compaction is performed, and tiles are set on the roof.
  6. In the last step, a mixture of cement and sand is applied to the tiles to seal their joints.

Latest Technology

The advanced methods are almost the same as conventional methods. The major difference lies here in the latest technology. Chemical coatings are used instead of coal tar and polythene, which are relatively expensive.

Which Method is More Effective?

Do many people ask that out of both these waterproofing roof methods, which one is more effective? There is no definite answer to this question. But we can say that the conventional method is quite old and cheap. It has remained effective for a long time. On the other hand, the latest waterproofing methods for the roof are almost the same as conventional ones. But it is a bit expensive due to the involvement of some chemicals.

Are there any other Preventive Measures?

Yes, there are other measures as well, and only these roof waterproofing solutions will not be enough to cure the issue of seepage and leakage. You should take some other important steps during construction, and the builders usually ignore them. So let us tell you about them:

The joint of the roof and the curtain wall or the roof’s edge is the weakest zone for water leakage. Here at this point, you will have to take some extra measures which will ultimately cast huge benefits to your building.

While making the parapet wall at this point is generally made of 4.5 inches of brickwork. You can just make the first two strips with 9 inches of brickwork, known as Fillet or Gola. By following this simple method during the construction of your house, you can make it seepage and leakage-proof.

Final Words

We hope that you have learned a lot about waterproofing by now. You can follow all the steps mentioned above to treat the issue of seepage and leakage in your house. You can hire the services of any roof waterproofing company and protect your house and yourself from several diseases.
