Why Waterproofing Terraces Early Is Important & How to Do It

 

A new terrace can be converted into beautiful and functional spaces like an outdoor seating area, a BBQ kitchen, a garden, or a solar panel area. Waterproofing is necessary to protect these spaces from wear and tear and ensure their structural integrity. Moreover, if you know the right way to waterproof without mistakes, you can reduce expenses on future repairs and maintain your property value. 

Read on to learn why waterproofing terraces early on is essential and how to do it correctly. 

Why Is It Essential to Waterproof Terraces Early?

1. Stops Water Infiltration

Waterproofing early on is like a permanent solution for roof leakage. Terraces are exposed to rain and mist, which causes water or moisture to seep into the concrete. This permeation produces leaks, sometimes visible as damp patches on the walls of the floor below. It leads to cracks, corrosion, and reduced structural integrity. Waterproofing terraces early makes the surfaces resistant to water infiltration and protects the interior spaces.

2. Increases Lifespan of Terraces

A terrace that is waterproofed early can prevent cracks, leaks, and rust, thereby ensuring durability. Automatically, it adds to the lifespan of the terrace’s concrete, tiles, and stones.

3. Prevents Mould Growth

Water buildup in the terrace causes dampness where spores thrive. This mould growth affects the air quality and produces stench, allergies, and respiratory risks. A new terrace that is waterproofed guarantees zero mould growth for years.

4. Saves Time and Money

Waterproofing early is a brilliant roof leakage solution that can prevent frequent repairs, saving you time, money, and energy in the long run.

5. Increases Property Value

Buyers are now aware of the importance of a well-maintained terrace, especially in areas prone to rainfall. A commercial or residential space with a waterproofed new terrace will attract many potential buyers.  

How Waterproofing Terraces Can Be Done Efficiently

1. Choose the Right Waterproofing Method

Based on factors like terrace size, location, and construction materials, you can choose the right waterproofing method. Some common waterproofing methods are:

• Polyurethane Waterproofing: It uses a liquid waterproofing membrane that prevents cracking, peeling, and UV degradation of the terrace surfaces.
• Sheet Membranes: Made of rubber or bitumen, sheet membranes are applied in layers and are effective in protecting large terraces.
• Cementitious Waterproofing: It bonds well with concrete, so, they are perfect for concrete terraces.

2. Ensure Proper Slope and Drainage

It is important to have a well-structured slope and drainage system for terrace waterproofing to effectively work. Faulty slopes and drainage cause standing water, thereby increasing the risk of leaks and damage. Terraces need to have at least a 1-2% slope to guide water towards the outlets. Also, consider installing multiple drainage points to prevent water accumulation, especially during heavy rainfall.

3. Use High-Quality Waterproofing Coatings

It is not just the method of waterproofing but also the quality of the waterproofing coatings that make a difference. Always invest in premium waterproofing products because they are weather-resistant, flexible, and protect materials from cracking.

4. Perform a Flood Test

It is beneficial to conduct a flood test to ensure the waterproofing has been done perfectly. Fill the terrace with water after intentionally clogging the drains. Allow the water to sit for at least 24-48 hours.  Then, scrutinise to see if there are any minor or major leaks, especially at joints, edges, and corners. Inspect both the terrace and the walls of the floor below, to see if any damp patches are formed. 

A successful flood test will give you confidence that your terrace is thoroughly waterproofed.

5. Regular Maintenance and Inspections

Waterproofing is not a one-time task. For a long lifespan of your terrace, you need to regularly inspect and check for any signs of cracks, stains, or moulds and do maintenance accordingly. Make sure to unclog the drains from time to time so that the water flow is not restricted.

6. Waterproof According to Climate

Waterproofing terraces must be based on the climate associated with the region your building is located at. Here is a short guide:

• Rainy climates: Opt for highly water-resistant waterproofing systems, like liquid-applied membranes, that can handle continuous water exposure.
• Hot and dry climates: UV-resistant waterproofing is suitable as it withstands the harsh sun and prevents cracks.
• Cold climates: Choose flexible waterproofing systems that can handle freezing and thawing cycles without becoming brittle.

Sunanda’s Solutions for Effectively Waterproofing Terraces

Sunanda Global is the best waterproofing company, offering a wide range of options for choosing the right waterproofing products. We make sure to constantly improve our waterproofing solutions for durable, affordable, and user-friendly products. Our POLYALK WP and SUNEPOXY WP+ are the right options to waterproof your new terrace. 

POLYALK WP

POLYALK WP is a polymeric waterproof chemical for roof designed for various applications, including flat or sloping roof slabs, walls, chajjas, vaulted roofs, domes, flooring, and overhead water tanks. 

This coating, easily mixed with cement, forms an impermeable co-matrix film. It is ideal for damp or moist conditions, even during monsoon spells. Its alkaline nature ensures compatibility with concrete while providing high flexural strength and excellent adhesion. This prevents carbonation and enhances durability. 

To apply, thoroughly clean and moisten the surface 24 hours prior. Mix one part POLYALK WP with 1 to 1.25 parts of fresh cement, stirring continuously for a lump-free consistency. Apply the slurry with a brush or roller, adding two to three coats at 24-hour intervals. 

Allow the coating to set for 24-48 hours, then cure by sprinkling water on vertical surfaces and using moist gunny bags on horizontal areas for 2-3 days. For added durability, apply a protective screed or plaster on flat surfaces and an additional SUNEXT 8 coating on external surfaces.

SUNKOTE WP+ 

SUNKOTE WP+ is a single-component, UV-resistant, elastomeric acrylic waterproof chemical for roof and external walls. Suitable for both flat and sloping roofs, it’s effective on new and existing structures. 

This high-build, thick membrane forms a resilient, liquid-applied waterproofing barrier, accommodating cracks up to 2 mm and thermal movements. UV-resistant and anti-fungal, SUNKOTE WP+ offers high tensile strength, tear resistance, and strong substrate adhesion. Its non-toxic composition allows concrete surfaces to breathe. 

For optimal application, thoroughly clean and prime the surface with POLYALK WP. After the primer cures, apply two coats of SUNKOTE WP+ with a 24-hour interval, applying the second coat perpendicular to the first for uniform coverage. 

Allow the membrane to cure for 24-48 hours, then add a protective screed layer with adequate slope for enhanced durability.
