Our homes take a beating every day from the heat, humidity, and rain all working quietly to wear things down. The roof, being the first line of defense, often gets the worst of it. That’s where roof waterproofing comes in, not as a quick fix, but as protection that strengthens your home from the top down.

A recent joint study conducted by Nippon Paint and Malaysian Institute of Property and Facilities Managers (MIPFM) showed that nine out of ten buildings experience leaks or seepage, with roofs among the most common problem areas.

Limitations of Mainstream Waterproofing Systems

You might bump into “torch on membrane waterproofing’ when finding the solution to your problem. Torch on membrane is one of the most common roof waterproofing methods that is widely used by contractors. But is it the best solution for your roof issues? Let’s find out

1. Installation Method

Torch-on membranes require heating with a torch to adhere to the roof, producing toxic fumes that can harm the respiratory system. Installation is challenging, especially on smaller areas, and must be carried out by a trained professional due to safety risks

2. Durability

Torch-on membrane is fully waterproof but not breathable, so moisture can get trapped, causing bubbles. Contractors often need to pierce and patch these areas to release trapped air.

3. Cost and Maintenance

Torch-on membranes may be cheaper to install, but frequent repairs and reapplications make them more expensive over time.

Another issue with a flat roof is that it is not perfectly flat, so water can pool on the membrane. This leads to dirt buildup, mold, and stubborn stains that are hard to clean.

PU injection is another option but it is less reliable for large surfaces like roofs, as the exact source of the leakage is often hard to pinpoint.

6th Generation of Nanotechnology Waterproofing Solution

Nano-G’s 6th Generation Nanotechnology is the latest breakthrough in waterproofing. It uses extremely small particles that penetrate deep into a material’s pores, forming an invisible, water-repellent (hydrophobic) barrier from within to protect your concrete flat roof.

1. Application Method

Nano-G is applied as a liquid coating that soaks deep into the roof or walls, making it an effective roof waterproofing solution. There is no hacking and burn membranes needed, or disrupt the occupant, making the process fast, clean, and safe.

2. Durability

Because it penetrates the surface and forms a barrier from the inside, it lasts much longer than other solutions. Treated surfaces such as concrete flat roof and walls can withstand heavy rain, sun, and humidity without cracking, peeling, or losing effectiveness over time.

3. Environmentally friendly

Nanotechnology solution is breathable, hence it causes no bubbling issue like torch on membrane, and is patented with Greek Technology. This means our nanotechnology is safe-if-inhaled not only for the occupant, but also our applicator. This marks our dedication to not only providing solutions but also ensuring health, safety, and sustainability.

A Decade of Proven Excellency

For more than 10 years, Nano-G has been delivering reliable, long-lasting waterproof solutions that both homeowners and professionals trust. Among their notable projects are :

1. Commercial Buildings

Situated in Putrajaya, Hospital Putrajaya is a busy government hospital with over 23 years of service. When a leak appeared above their maternity ward, Nano-G stepped in. The team prepared the area and applied the nanotech solution, which penetrates deep to block water from within.

De Palma Hotel also faced persistent leaks in its bathrooms and surau. The team at Nano‑G waterproofed around 120 bathrooms and a surau, and carried out the work with minimal disturbance to guests.

2. Residential

At his home in Klang Valley, Dato AC Mizal was dealing with water leaks and slippery floors, which were a concern for his family. Nano‑G applied their nanotechnology waterproofing across balconies and kitchen areas, giving the family a peace of mind.

DJ Jack Yap’s residence faced persistent water leakage on a flat slab above his bedroom and other parts of his home. Our team inspected the area, found hairline cracks, and applied our nanotechnology waterproofing solution across multiple zones. An additional anti‑slip coating was applied in the bathrooms to improve safety.

 

Conclusion

With heavier rain and changing weather patterns, investing in high-quality roof waterproofing is no longer optional, it’s essential. With expert help like Nano-G and their nanotechnology solutions, homeowners and builders can now count on smarter, longer-lasting protection

At the end of the day, it’s not just about fixing leaks, it’s also about peace of mind. When your roof is secure, so is everything beneath it.

You’ve fixed it before. Maybe even a few times. You’ve called in contractors, applied waterproofing solutions, repainted the wall or ceiling, and thought it was over. But then, after less than a year, the water stains reappeared and the leak came back.

If that sounds familiar, you’re not alone. Across Malaysia, countless homeowners face the same frustrating cycle: repair, relief, repeat. You fix one area, and weeks later another wet patch appears sometimes in the same spot, sometimes somewhere new. It’s as if water always finds a way back.

Waterproofing continues to emerge as the common problem of leaks. A 2025 study found that 90% of buildings in Malaysia have leaks or poor maintenance issues. This has raised concerns about the safety and long-term value of many properties.

The finding also showed that most problems happen because of old buildings and outdated repair methods, where fixes are only done after the damage has already occurred. Many admitted to delaying waterproofing repairs due to cost, but this often leads to higher expenses later, safety risks, and a shorter building lifespan.

How Leaks Affect Your Surrounding

Getting leaks in your home is something most of us have faced, and it’s never fun. It might seem small at first, but leaks are a sign that something’s not right behind the surface. The harsh truth is, even a small leak can slowly turn into a big problem. This is where professional waterproofing solutions come in to protect your home. Here is what you should expect if leaks are left untreated :

1. Structural Damage

Water that seeps into concrete, walls, or ceilings can gradually weaken a home’s structure, compromising safety over time. For homeowners or real estate agents, persistent leaks also make the property less appealing to buyers or tenants, as they signal water damage and potential maintenance issues.

Water ponding on flat roofs often causes leaks that seep into walls and ceilings.

 

 

 

You’ll notice dark spots on ceilings or walls due to mould, which can trigger allergies or breathing issues, especially for kids or elderly family members.

Unattended water leakage problems often result in mould growth, which can appear on ceilings, affect occupants’ health over time, and reduce the aesthetic appeal of the space.

3. Electrical Hazards

Water exposure is one of the leading causes of electrical fires in homes. When water seeps into wiring, switches, or outlets, it can trigger short circuits and current leakage, significantly increasing the risk of fire. Long-term dampness in walls, roofs, or ceilings can also corrode hidden wiring and damage insulation, potentially causing overheating or electrical arcing, a common ignition source. Keeping all electrical areas dry and properly protected is essential for maintaining a safe home.

The Solution You Can Trust

Enough with the headache and let us help you with modern nanotechnology waterproofing systems. Over the years, Nano-G has continuously refined its waterproofing technology to meet the demanding conditions of Malaysia’s climate.

Through years of research and innovation, we introduced the advanced nanotechnology waterproofing system that was formulated in Greece; a breakthrough that works entirely from the surface without the need for hacking tiles or breaking floors.

The specially formulated waterproofing solutions penetrates deep into the material, sealing it from within to form a durable, invisible barrier that keeps your space clean, dry, and intact. This innovation revolutionised the way waterproofing is done, making it faster, neater, and longer-lasting, while saving homeowners from messy renovation work and downtime.
