Rainy Weather Waterproofing

Saint-Gobain Weber Hong-Kong

Hong Kong residents living in flats must take waterproofing seriously due to the subtropical climate characterized by hot and humid summers, high rainfall, and occasional typhoons. Failure to waterproof your flat may result in structural deterioration, mould growth, and health issues. However, with the right products, you can easily waterproof your flat and prevent water damage. Here are some product solutions from Saint-Gobain Weber that you can use for waterproofing Hong Kong flats:

Importance of Waterproofing

Waterproofing your house is essential to prevent water damage, which can have long-lasting effects and lead to expensive repairs. Some consequences of water damage include mould growth, wooden structure rotting, metal material corrosion, and electrical system damage. Water damage can also lead to health problems like respiratory issues, allergies, and other health conditions.

Moreover, waterproofing can increase the value of your property and enhance its longevity. A properly waterproof house is more attractive to potential buyers and can increase the market value of your property. Additionally, waterproofing can help protect your property against natural disasters, such as floods and hurricanes, which are becoming more frequent and severe due to climate change.

Various methods of waterproofing can be used to protect your house from water damage. These methods include:

Balcony and Roof Waterproofing Solutions

Due to their design, flat roofs and balconies can be more prone to water damage since they may not drain water as efficiently as sloped ceilings. Therefore, a reliable waterproofing solution protects your flat's roof and balcony. One suitable option is Weber's weberdry elastic slurry, it forms a seamless and flexible waterproofing barrier that effectively prevents water from penetrating through the roof and causing damage to your attic or ceiling.

Window leaking

Heavy and persistent rainfall may cause rain to leak into the window frame and damage the substrate. weberdry window grout is a high quality waterproofing cementitious mortar specially designed for window frame grouting to provide optimum water protection to the substrate.

Bathroom and Kitchen Waterproofing Solutions

High humidity and water accumulation in bathrooms and kitchens can cause mould growth and water damage. Therefore, you must use waterproofing products to create a barrier against water penetration. One such product is sealant products, interior waterproofing that involves sealing cracks and gaps in walls, floors, and foundations to prevent water from seeping through. While sealants can be effective in preventing water damage, they are not a long-term solution and may require regular maintenance.

Wall Waterproofing Solutions

Cracks and wall gaps can allow water to seep in, leading to structural damage over time. To prevent this, it's crucial to use a durable waterproofing solution that can withstand exposure to the elements. Weber offers a range of products designed to address this issue, such as webertec ACE, which seals cracks in reinforced concrete. In addition, our waterproofing renders and epoxy tiling solutions are specifically designed to prevent water from seeping through walls, providing an effective barrier against water damage.


It is essential to remember that waterproofing is not a one-time fix. Regular maintenance and inspections are necessary to ensure that the waterproofing methods are still effective and that there are no new issues. Proactively investing in proper waterproofing protects your house from water damage and ensures its longevity for years.
