Cause of Defects
- Short gully pipe together with lack of provision of waterproofing membrane at floor trap may contribute to the water seepage as illustrated in Figure 1.
- Aging of waterproofing membrane could lead to the failure of water-tightness of the penetration. Generally, the durability of waterproofing membrane is 10 – 15 years.
- Poor fixing due to poor sitework of plumbing may lead to water leakage through pipe joints.
- Prolonged contamination of water subsequently could cause corrosion and damage the protective coating.
