Top 5 Waterproofing Problems

Waterproofing issues in Singapore are more common than you think.

In a country that experiences high humidity and significant annual rainfall, the challenges of keeping your buildings and homes protected from water damages are plenty.

Among these challenges, the top 5 common waterproofing problems that many property owners face include: roof leaks, bathroom waterproofing failures, rising dampness, balcony and planter box seepage, and window seal and facade cracks

1. Roof and Ceiling Leaks:

Roof leaks are a frequent problem, especially after heavy rain, due to poor drainage, damaged membranes, or structural movement. This is a common issue faced by HDB owners.

2. Bathroom Waterproofing Failures:

Bathrooms are particularly vulnerable to leaks caused by cracked tiles, worn-out grouting, or damaged membranes under the floor. Once damaged, water easily seeps through leading to dampness and mold growth.

3. Rising Damp:

Ground floor units are susceptible to rising damp, where moisture from the ground seeps into walls and floors. This is especially common during monsoon seasons in Singapore's humid weather.

4. Balcony and Planter Box Seepage:

Balconies and planter boxes can be sources of water seepage. When water is not properly drained, the moisture easily accumulates and can potentially damage the interior of the property.

5. Window Seal and Facade Cracks:

Cracks in window seals and facade, coupled with Singapore's weather conditions, can lead to water damage and leaks.
