Understanding Spalling Concrete: Causes and Symptoms

Few sights are more alarming to a Singapore homeowner than rust-stained patches or flaking pieces of concrete falling from the ceiling. This common issue, known as spalling concrete, is not just an aesthetic problem; it’s a structural warning sign caused by the corrosion of steel bars inside your ceiling slab—a frequent occurrence in older HDB flats exposed to our tropical humidity. Dealing with spalling requires immediate, expert attention and compliance with HDB standards.

HDB Compliance, Assistance, and Prevention Tips

As a responsible homeowner in Singapore, understanding your role in maintaining your flat—and knowing when to ask for help—is crucial for safety and compliance.

A. HDB Regulations and Owner Responsibility

For spalling concrete, the rules are clear:

1. Homeowner's Responsibility: The HDB states that spalling concrete is a maintenance issue, not a structural defect of the entire building. Therefore, the flat owner is responsible for the prevention and repair of any spalling within their unit.

2. Act Fast: If spalling is left untreated, the corrosion spreads, increasing the repair cost and potentially causing dislodged concrete to fall and cause injury.

3. Engage a Registered Contractor: While HDB may provide a list of contractors, the engagement is private. However, it is always advisable to engage an HDB Registered Renovation Contractor (RRC) like Handyman.sg to ensure the work is carried out to acceptable standards and safety precautions are followed.

B. Financial Assistance: The Goodwill Repair Assistance (GRA)

Did you know you might qualify for financial help?

• For owners of older HDB flats, the Housing & Development Board may offer the Goodwill Repair Assistance (GRA) scheme.

• Under this scheme, HDB may co-pay 50% of the repair costs, capped at a certain amount per flat.

• Actionable Tip: Always check with your local Town Council or HDB Branch office before starting the repair to see if your flat qualifies for the GRA scheme and to understand the subsidy limits.

C. Spalling Concrete Prevention: Your Maintenance Checklist

Since humidity and carbonation are the main culprits in Singapore, prevention relies heavily on managing moisture in your flat.
