Spalling Concrete Complaints Received after Defects Liability Period for Home Improvement Programme

Speakers

Summary

This question concerns the volume of spalling concrete complaints following the Home Improvement Programme’s (HIP) defects liability period and whether additional subsidies will be provided for aging flats. Mr Pritam Singh questioned the frequency of such reports and the impact of deteriorating structural materials, while Minister for National Development Mr Lawrence Wong responded that spalling is a maintenance issue caused by natural wear and tear. Minister for National Development Mr Lawrence Wong stated that an average of 13 cases per 1,000 units are reported annually after the one-year liability period. He highlighted that while HIP repairs are fully funded by the Government, subsequent cases are eligible for assistance under the Goodwill Repair Assistance scheme. Through this scheme, HDB facilitates the necessary repairs and co-pays 50% of the costs to assist flat owners with maintenance.

Transcript

24 Mr Pritam Singh asked the Minister for National Development (a) how many cases of spalling concrete happening after the defects liability period has the HDB received for flats that have undergone the Home Improvement Programme (HIP); and (b) whether HDB will consider additional support or subsidies for flat owners in such cases as flats age and the integrity of structural materials, such as ceiling reinforcement bars, deteriorate.

Mr Lawrence Wong: Spalling concrete is the flaking of concrete from the ceiling due to the corrosion of steel reinforcement bars in the concrete floor slab. The corrosion is caused by the ingress of moisture and acidic elements and can lead to cracking and bulging of the concrete cover over time. This is a natural wear and tear process and is generally a surface maintenance issue which can be mitigated through regular painting of the ceiling. With regular maintenance, spalling concrete is usually minor and can be easily repaired.

The repair of spalling concrete is one of the essential improvements carried out under the Home Improvement Programme (HIP), where it is fully funded by the Government. However, this does not preclude the re-occurrence of spalling concrete or occurrence in another area of the flat, as wear and tear will continue over time.

This is why there will be cases of spalling concrete even after the completion of HIP or its defects liability period (DLP). Based on experience, after the one-year DLP, an average of about 13 such cases per 1,000 dwelling units are reported to the Housing and Development Board (HDB) per year.

For all spalling concrete cases after DLP, flat owners can request for assistance under the Goodwill Repair Assistance scheme, where HDB will help to carry out the repairs and co-pay 50% of the repair cost.
