FAQs About Waterproofing in Singapore

What is waterproofing?

Waterproofing is a protective process that prevents water infiltration into buildings and structures. It involves applying water-resistant membranes, sealants, or coatings to surfaces such as roofs, walls, and foundations. In Singapore’s tropical climate, waterproofing plays a vital role in protecting homes and commercial buildings from heavy rainfall, high humidity, and water seepage-related damage.

Waterproofing is especially critical in Singapore due to its tropical climate, which brings high humidity and frequent heavy rainfall throughout the year. These conditions create the perfect environment for water seepage, mould growth, spalling concrete, and structural deterioration, especially in older HDB flats, condos, and landed properties. Without proper waterproofing, persistent moisture can compromise the integrity of roofs, ceilings, and foundations, leading to costly repairs and potential health risks such as poor indoor air quality.

From leaky bathrooms to water seepage on walls, we’ve got you covered. Our waterproofing services in Singapore include concrete roof surfaces, bathrooms, external facades, and carpark decks. Whether you’re a homeowner living in an HDB or condo, or a facility manager overseeing a commercial or industrial property, we provide tailored solutions to keep your space dry, durable, and protected in Singapore’s humid and rainy climate.

The cost of waterproofing in Singapore varies based on factors such as the size and condition of the area, the chosen waterproofing method, accessibility, and whether any repairs are needed beforehand. To ensure accurate costing and effective long-term protection, it’s best to consult an experienced waterproofing specialist in Singapore for a detailed on-site assessment and tailored recommendation.

The duration of a waterproofing project depends on the scope of work involved. Smaller projects like bathroom waterproofing may take a few days, while larger projects like basement or roof waterproofing could take several weeks. We provide a clear timeline for completion before starting any project.

Yes, we offer warranties on our waterproofing services, demonstrating our confidence in the quality of our workmanship and materials. The warranty period varies depending on the type of service and materials used. We provide detailed warranty information before commencing any project.

With proper application and regular maintenance, waterproofing can last between 10 to 15 years. This depends largely on environmental exposure and the type of materials used, especially for areas like concrete roof waterproofing, where durability is key.

While DIY waterproofing might seem like a cost-saving option, it’s often ineffective and may lead to more damage in the long run. For lasting results, it’s best to engage a professional water leakage specialist in Singapore who has the right tools and experience.

Yes. Proper waterproofing prevents water ingress, which is the primary cause of mould and mildew growth in damp areas. Effective water seepage repair solutions are crucial in maintaining a mould-free indoor environment.
