You can protect your terrace and home by extension by learning how waterproofing works, what waterproofing methods are available, and a step-by-step guide on how to waterproof for terrace.
What to Know About Rooftop Treatment
Before we look at the step-by-step process of waterproofing in terrace, let’s first look at some of the important things to keep in mind:
- Climate: If you live in regions with heavy monsoons, then you need a long-lasting terrace waterproofing solution that can withstand such a climate.
- Terrace Surface: Different terrace surface needs different roof waterproofing solutions, so evaluate your terrace surface before beginning waterproofing in terrace.
- Damage: Before you begin waterproofing terrace, you need to check for existing cracks, leaks, or other weak spots.
- Waterproofing Materials: Out of so many roof waterproofing solutions out there, choose the one that benefits your roof the most. Remember, each waterproofing treatment solution suits different terraces, so choose the one that suits your terrace surface, weather, and also budget.
Waterproofing Solutions for Roof: Traditional & Modern
There are different ways to waterproof a roof, with each having its own benefits. Which water proofing of terrace you pick depends more on your budget, terrace surface, and long-lasting requirements.
Traditional Waterproofing Methods:
1. Brickbat Coba

The Brickbat Coba waterproofing method involves layering bricks over the waterproof solutions for roof to avoid water seepage. This method is traditional, indeed, but effective. However, neglecting regular maintenance of your terrace might cause cracks to form in your roof over time.
2. Lime Terracing

The lime terracing waterproofing method is when you mix lime, powdered brick, and jaggery water. This mix is then poured over concrete to provide a protective waterproofing layer. This method is used in old house terraces and is long-lasting, but it also needs regular maintenance.
3. Mud Phuska

Another traditional waterproofing method that can be used to waterproof a roof is mud phuska. This method is cost-saving as it involves a layer of clay and bhusa sand. It is the best method for regions with hot climates and smaller budgets. While it is cost-saving, the mud phuska method could be time-consuming.
Modern Waterproofing Methods:
1. Polyurethane Waterproofing
When we talk about modern roof waterproofing methods, the first one is polyurethane coating. This method forms an elastic-like barrier over the terrace surface, preventing cracks and leaks on the roof. This method is UV-resistant and good for terraces in regions with extreme climate conditions.
2. Liquid Waterproofing

This waterproofing in terrace method uses a hydrophobic liquid strengthened by glass to create a waterproof layer on the roof. This method is cost-saving and can be good for different terrace surfaces. Also, it is easy to apply and is long-lasting. However, it needs multiple coats to ensure proper waterproofing in terrace.
3. Cement-Based Solutions
The cement-based solution is another modern waterproofing treatment that is mixed and applied like plaster on the roof. This solution is used for terraces, bathroom roofs, and balcony roofs to prevent water damage and leaks.
4. Bituminous Waterproofing

Among modern waterproof treatments, bituminous waterproofing is an excellent one. This method involves applying a bitumen (a type of petroleum) on the terrace that acts as a strong waterproof barrier. This application is often reinforced with fibreglass to strengthen its durability.
5. Acrylic-Based Waterproofing
Another effective method for waterproofing in terrace is acrylic-based treatment. This can be applied using a roller, ensuring even coating. The layers from this solution have high tensile strength and are UV-resistant. Moreover, they come in different colours and shades, making your roof look visually appealing.
How to Begin Waterproofing in Terrace: Steps To Know!
1. Prepare the Surface
To begin waterproofing in terrace, the first thing you need to do is clean your rooftop properly. Make sure you remove all dirt, dust, and debris from your roof before you begin waterproofing a roof. If you see any cracks, fill them with suitable compounds.
2. Apply a Primer
Once you clean and prepare your terrace, use a waterproofing primer and apply it on the surface. This will help the coating bond better with the terrace surface. Then, let the primer dry completely before you move to the next step.
3. Apply Waterproofing Solution for Roof
Next, depending on the method you pick (bitumen, mud phuska, liquid waterproofing, etc.), apply the waterproofing layer on the terrace evenly. Remember to follow the manufacturer’s instructions carefully.
4. Apply Reinforcement Layer
Now, once the waterproofing layer is in place, add a reinforcement or protective layer. This means tiles, cement, or fibreglass to make it long-lasting. This will prevent everyday wear and tear on your terrace.
5. Apply a Final Coat
Next, you need to apply a final coat of waterproofing solutions for better protection. This will help you strengthen the waterproofing treatment and fill any gaps left in the initial coating.
6. Have Regular Checks
Keep in mind that waterproofing for roof isn’t a one-time fix. This means that you need to have regular checks to ensure no cracks or water seepage are seen. If there are, then reapply the solution as needed.
