Waterproofing Your Terrace: Key Considerations and Solutions

Waterproofing your terrace is crucial to protect your property from water damage and ensure the longevity of your structure. In this blog, we will discuss the key considerations and solutions for the waterproofing of terraces.


Owning a home with a terrace is a wonderful luxury, providing you with a private outdoor space to relax, entertain, and enjoy the views. However, this elevated open area is constantly exposed to the outdoors, making it vulnerable to water damage. Whether you experience heavy rainfall or live in a region with extreme weather conditions, ensuring your terrace is waterproofed is crucial to maintain its structural integrity and extend its lifespan.


Proper terrace waterproofing is essential to prevent water seepage and leakage, which can lead to structural damage and other issues. By taking the necessary steps to waterproof your terrace, you can ensure its durability and avoid costly repairs in the future. From identifying potential problem areas to choosing the right waterproofing materials, we'll cover everything you need to know to safeguard your property and preserve the beauty of your terrace.

Key Points to Consider While Waterproofing for Terraces

1. Evaluate the structure

Before starting the waterproofing process, it is important to assess the existing structure of your terrace. Look for any cracks, gaps, or damaged areas that need to be repaired before applying terrace waterproofing solutions.


2. Surface preparation

Proper surface preparation is essential for the waterproofing material to adhere effectively. Ensure that the terrace surface is clean, free from dust, debris, and any loose materials.


3. Selecting the right waterproofing material

There are various waterproofing materials available, each with its specific advantages and suitability for different terraces. Choose the one that aligns with your terrace's requirements, climate conditions, and budget.


4. Crack and gap filling

Even minor cracks and gaps can lead to significant water seepage. Fill these gaps with suitable sealants to ensure a watertight surface.


5. Weather Resistance

Consider the weather conditions in your region and choose a waterproofing solution that can withstand extreme temperatures, UV radiation, and heavy rainfall.

What are Some Waterproofing Solutions for Terraces?

When it comes to the waterproofing of terraces, there are two broad categories of solutions available: traditional methods and modern methods. Each comes with its characteristics and steps, offering distinct advantages in safeguarding your terrace against water damage.



Traditional methods of waterproofing for terrace

Traditional methods of waterproofing for terraces have been widely used and have proved effective over the years. These terrace waterproofing methods typically involve the application of different layers of waterproofing materials. Here are the characteristics and steps involved:


1. Brickbat coba method


This traditional method involves placing flat bricks on the roof with gaps between them. Cement is then used to bond the bricks and create a dense slurry mixture that fills in the gaps. When left to cure, water is added onto the roof and left in that state for at least 2 weeks. It is important to note that this method adds significant weight to the roof, and if water infects the surface, the process needs to be repeated.


2. Lime terracing method 

In this method, a mixture for waterproofing is created using lime. The lime molasses mix is then sprayed on a concrete layer to aid in waterproofing. Once completed, the roof undergoes curing and regular watering intervals. However, it should be considered that this method may not be long-lasting, and if water infects the surface, the process will need to be redone.


3. Mud phuska method

This method is suitable for hot areas with a limited budget. It involves using a waterproofing solution made from clay and bhusa sand. The finished layer is plastered using a mixture of cow dung and mud, and proper curing is necessary for it to remain waterproof. This method is usually considered to be time-consuming, and the use of a roof adds stress to the structure.

Modern methods of waterproofing for terrace

Modern methods of the waterproofing of terraces offer improved durability and superior protection against water damage. These methods often involve the use of advanced terrace waterproofing chemicals, products and technologies. Here are the characteristics and steps involved:


1. Bituminous roof waterproofing

This method involves using bitumen, a form of petroleum, which is applied as a protective layer on the roof. Bitumen is viscous and sticky, making it an excellent choice for waterproofing roofs. It is easily fixed to the surface by using fire, with the addition of other additives to make it flexible alongside waterproof. However, it is important to note that bitumen is not a sustainable material, and UV exposure may reduce its effectiveness.

2. Liquid deck roof waterproofing

This method utilises a hydrophobic liquid fortified with glass to create a waterproof coating on the terrace. The liquid membrane is highly flexible, cost-effective, and can be applied on various surfaces such as concrete, asphalt, and bitumen. This is a hassle-free method that also has a long lifespan and will require multiple coats to ensure proper waterproofing.



3. Acrylic-based roof waterproofing coats


Another popular method is using acrylic-based waterproofing coats, which can be applied proportionately using a roller. These coats offer high tensile strength, UV resistance, and prevent the growth of mildew. Additionally, they come in various colours and shades, enhancing the aesthetic appeal of your terrace.


Choosing the right waterproofing solution is essential to protect your terrace from water damage and ensure its longevity. Traditional methods have been time-tested, but modern methods like using UltraTech Weather Pro WP+200 and UltraTech Weather Plus Cement offer better prevention from dampness, higher durability and performance for long-lasting protection.

Steps to Waterproofing on Terrace

To ensure successful terrace waterproofing, it is important to follow a series of steps. Here is an overview of the process:


1. Preparing the surface

Clean the terrace surface thoroughly, removing any dirt, debris, or loose material to ensure that the surface is smooth and free of any irregularities.


2. Repair or strengthening of weakened substrate

Identify and repair any cracks or weakened areas on the terrace surface and fill in the gaps using a sealant, mortar or other additives. This should be done to ensure a strong base for the waterproofing layers.


3. Apply primer 

Apply a primer to enhance the adhesion of the waterproofing materials to the terrace surface. The primer improves the bonding between the substrate and waterproofing layers. 


4. Apply base coat

Apply a base coat of the chosen waterproofing material evenly onto the surface. The base coat acts as the primary waterproofing layer and provides a seamless barrier against water penetration.


5. Apply reinforcement

If necessary, reinforce the base coat with a fibreglass mesh or similar material to strengthen the waterproofing layer.


6. Apply intermediate coat 

Apply an intermediate coat of waterproofing material for added protection and durability. This coat further strengthens the waterproofing barrier and fills any voids in the base coat.


7. Apply topcoat

Finish with a topcoat to provide the final layer which provides UV resistance and protects the underlying layers of waterproofing and ensures long-lasting results.

In conclusion, waterproofing your terrace is a vital investment to protect your property from water damage and ensure its longevity. Proper waterproofing of terraces involves careful consideration of the surface, choosing the right waterproofing material, and following a step-by-step process for its application.
