Waterproofing should protect your home or building for years. Yet, many property owners in Singapore face recurring leaks on their roofs, walls, or floors—sometimes just months after repairs.

Why does this happen? The answer lies in common mistakes during waterproofing projects. At Triton Construction, we specialise in preventing these issues with proven methods and quality materials that deliver long-term protection.

Common Contractor Mistakes

1. Usage of Low-Quality Materials

Cheap waterproofing products may look cost-effective at first, but under Singapore’s humid weather, heavy rainfall, and harsh sun, they quickly break down. Once the membrane or coating deteriorates, leaks return—often worse than before.

2. Poor Application Workmanship

Even premium materials fail if applied incorrectly. Common mistakes include:

  • Uneven membrane layers
  • Poor joint sealing
  • Rushed installation without surface preparation

These errors leave gaps where water can seep through, causing repeated leakage problems.

3. Overlooking Hidden Problem Areas

Some contractors only fix visible leaks and miss the root of the issue which are mostly the critical areas such as:

  • Window and door frames
  • Balcony planter boxes
  • Roof gutters and tile overlaps
  • Wall cracks near corners and beams

When these weak points are ignored, new leaks appear soon after.

4. Lack of Maintenance

Waterproofing is not a permanent “set-and-forget” solution. Over time, wear and weather can weaken systems. Without regular maintenance, even strong waterproofing may fail prematurely.

5. Hiring Inexperienced Contractors

Unqualified cheap and general contractors often provide quick, temporary fixes instead of addressing the root problem. This results in recurring water seepage, wasted money, and costly repairs down the line.
