1. How long does waterproofing last?

The lifespan of waterproofing depends on the materials used and the environment it’s applied to. Typically, waterproofing can last between 5 to 10 years, but this can vary. For example, roof waterproofing might last 10 to 15 years, while bathroom and basement waterproofing could last 5 to 10 years. Environmental factors such as weather conditions, building wear, and maintenance can impact the longevity. Regular maintenance and repairs, such as re-sealing joints or clearing drainage, can extend the effectiveness of waterproofing. Always consult a professional to assess and ensure long lasting protection for your property.

2. What is the cost of waterproofing services?

The cost of waterproofing services in Singapore varies based on factors like the type of service, the area to be waterproofed, and the materials used. Here’s a general breakdown:

3. How do I know if my property needs waterproofing?

In Singapore’s humid climate, you may need waterproofing if you notice:

• Water stains or dampness on walls, ceilings, or floors.
• Mold or mildew growth, especially in bathrooms or basements.
• Cracked walls or floors allowing water seepage.
• Peeling paint or wallpaper due to trapped moisture.
• Flooding or puddles in basements, balconies, or roof areas.

These signs suggest moisture problems, and it’s best to consult a waterproofing professional for inspection and solutions.

Common waterproofing solutions in Singapore include:

• Cementitious – Applied to walls and floors, ideal for bathrooms.
• Liquid Membrane – Flexible, seamless coating for roofs and balconies.
• Polyurethane (PU) – Durable, for roofs and basements.
• Bituminous Membrane – Asphalt-based, used for roofs and foundations.
• Injection Grouting – Seals cracks, typically for basements.

Each method is selected based on the area, environmental factors, and specific needs of the property.
