Apartment balconies with concrete cancer, in St Lucia, South of Brisbane.
Balconies with concrete cancer. Identified by Peter Weddell Qld Home Buyers Inspection Service.
- Seepage through the concrete to the steel reinforcing causing concrete cancer (spalling).
- Reinforcing being too close to concrete surface or edges causing it to rust then expand which causes fracturing of the concrete.
- Remove all fractured concrete and rusted reinforcing
- Treat exposed reinforcing with anti-rust treatment that is suitable for hash conditions
- Apply a bonding compound to the original concrete slab edge.
- Secure additional reinforcing for new concrete. It must be correctly secured to the existing slab
- Refit new concrete.
- Seal and waterproof any joints (gaps) to avoid seepage and deterioration from recurring
Balconies with concrete cancer (spalling). Important points:
- Although this would be covered by the Body Corporate, it would still be very costly to the unit owners. Especially if the sinking fund is limited.
- Unfortunately the greater majority of building inspectors will not inspect the exterior of apartment blocks, even when they are easily accessible.
Limited access by inspectors can prove to be costly, for potential buyers!
