Best Waterproofing Solutions for Indian Climate

Even though India has a tropical climate, the monsoon more or less covers the whole country. The arrival of the monsoon makes many people happy because it provides instant relief from the scorching summer and is a boon for our farmers and economy. However, it’s also a serious concern because of flooding in various areas and it could lead to water leaks and damp spots across the house, especially on the exterior surfaces. Waterproofing materials save the day, and there are different types of waterproofing materials for different surfaces.

Infrastructure is a growing field in a country like India that is still developing. A lot of new products are introduced and available to help keep the water out. In this article, we are going to explore different methods of waterproofing and ways to choose the best waterproofing solutions for Indian climate conditions.

For the Indian Climate: Different Methods of Waterproofing

Waterproofing Using Cement

One of the most popular types of waterproofing is waterproof plaster, which has been used in most commercial constructions and even some residential constructions. Cement is a common material used in the construction industry. It is a good option to waterproof the walls of a building. Waterproof plaster is a dry plaster mixture that includes waterproof material that is applied at the time of construction. This method of waterproofing creates a barrier between the surface and water. Waterproof plaster uses hydrophobic material that acts as a water repellent.

Waterproofing Using Tar

Tar is a black viscous substance that is extracted from the pine tree. It is a commonly used substance in the construction industry. It is a good choice to waterproof the roof of a building. Tar made from asphalt is mostly used as a dampproof for walls and roofs against water. Painting tar on the surface helps to stop water from entering the walls and roof. But tar made from asphalt isn’t really a good way to keep water out. If you put tar on your walls and roof, it won’t keep water out, but it will stop water from getting in.

Waterproofing Using Lining

The needle-punched geosynthetic lining method focuses on making needle-punched geosynthetic liners for protecting against the environment, water work, and waterproofing infrastructure. This method uses composite materials that are strong and light because they combine the characteristics of resin and glass. Most of the time, the material used in this method is either woven into the fiberglass or in the portion of glass strands.

Waterproofing Using Bitumen

A membrane made of bitumen is used for waterproofing a roof made of reinforced concrete. Bitumen is a black, sticky substance that is extracted from coal tar. It is a commonly used substance in the construction industry. It is a good choice to waterproof the roof of a building. Before installing these membranes, you should read the guidelines and safety instructions that the manufacturer has given you. When using this membrane, fire protection and preventative measures are the most important things. All things that can catch fire should be taken off the roof, and good roofing techniques should be used. Using blowtorches, the bitumen waterproofing membranes are spread out on the site and stuck to the surface with tar-based glue.

Waterproofing Using Polyurethane

This is the most popular waterproofing method in India and most other countries around the world. Almost every residential structure in India uses this waterproofing method. Polyurethane waterproofing paint is a coating made of a membrane that prevents dampness and seepage, forms a barrier against the water, and stops microbes from growing that need moisture to live (such as mold). It is often made with a base of oil, latex, or concrete. Combining all these can make a strong seal that keeps water out.

Things To Consider While Choosing The Best Waterproofing Solution

Each waterproofing product is different in how well it keeps out water, how well it reflects UV light, how long it lasts, and how it is applied. This buyer’s guide below will help you to make a wise decision while looking for the best waterproofing solution.

Water Resistance

Every sealant keeps water out to some degree, but polyurethane, rubber, and silicone are the most effective waterproof materials. This means that your roof can handle heavy rain and stagnant water. But your sealant will need more than one layer to make a completely waterproof barrier.

UV Reflectivity

Keeping your house cool is easier with a waterproofing sealant that can reflect solar light. During the summer, this is especially helpful because it can cut down on the use of air conditioning and lead to a lower energy bill. The most reflective sealants are made of rubber, acrylic, and silicone. The color of a sealant also affects how reflective it is, as lighter shades reflect better than darker ones.


Different waterproofing materials have different life spans, but most last between 10 and 20 years. Rubber coatings last a little bit longer with just one layer, but the liquid types may need more than one coat since a thicker coating usually lasts much longer. Another thing that affects how long something lasts is how it is used. If you are not following the manufacturer’s instructions, the sealant won’t last as long. Most waterproofing product makers recommend not using it in cold weather or on a wet or dirty surface, as it might not be applied perfectly.


There are different ways to use each type of waterproofing product. The tape kind of sealant is easy to figure out how to apply, but the other types of material come in paint or spray form. With the paintable waterproofing method, you get a thick coat of sealant, that is enough to cover a large area. Sprayed waterproofing is easier to use, but it covers less area, so it is ideal for small or spot leakage.


In conclusion, the choice of waterproofing solution will depend on the type of material you want to waterproof. The most common materials used for waterproofing are bitumen and polyurethane. Each of these has its own pros and cons, and each needs to be chosen based on the needs of your project.
