Ms Mariam Jaafar: To ask the Minister for National Development with regard to the repair of ceiling leaks in HDB flats (a) whether there is any update on the inclusion of overlay waterproofing membrane system as an offering under the Goodwill Repair Assistance (GRA) Scheme; and (b) whether the Ministry is considering the inclusion of chemical infusion as an offering under the GRA Scheme.
Answer:
Ceiling leaks that occur in HDB flats are generally a result of wear and tear over time. In such cases, the responsibility for repairs is shared jointly between the upper and lower-floor flat owners. Both upper and lower-floor flat owners should jointly investigate and carry out the necessary repairs. In most cases, ceiling leaks can be amicably resolved when flat owners exercise mutual understanding and cooperate with one another for investigation and repairs.
In cases where the leak is caused by wear and tear, HDB may offer assistance to residents via the Goodwill Repair Assistance (GRA) scheme, where HDB co-pays 50% of the repair cost, with the remaining 50% co-shared equally between the upper and lower-floor flat owners.
HDB has been exploring new technologies to improve current repair methods for toilet ceiling leaks, and has identified two new repair methods – nanotechnology waterproofing system, and overlaying waterproofing membrane system. These technologies provide alternative repair options for residents who do not wish to hack their toilet tiles or who prefer to keep their existing finishes in their toilets.
The nanotechnology waterproofing system is similar to chemical infusion, where the repair method involves an application of chemical solutions onto existing tiles to prevent the penetration of water. Such repair works are currently offered under the GRA scheme.
HDB is assessing the effectiveness of the overlaying waterproofing membrane system in resolving ceiling leaks, and whether it will be offered under the GRA scheme, to be completed by year end.
