Drainage problem with a unit-balcony, Brisbane City,
Building inspection carried out by Peter Weddell identifying a Unit-balcony drainage problem, in the city of Brisbane.
Problems with this unit balcony:
Combination of concrete top below railings being higher than the inside floor levels and very little differences between the balcony and inside floor levels also inadequate floor drains fitted to balconies of this new unit.
Recommend rectification by fitting (before or as problems occur):
- Fit vertical gaps within concrete below railings, to avoid trapping of water and allow it to escape before it enters the unit interior (recommended).
- A larger drain to the restricted opening.
- An awning that can be pulled down when necessary, for protection.
- Additional or larger drains to the balcony floors.
- Increase sliding door sill height by fitting an aluminium right angle and seal.
Another balcony of the same unit with undersized floor drain.
Drain cover removed to show size of the small drain.
Very little differences between the balcony floor tile level and the inside floor. This is most likely to allow water entry to the unit interior in adverse weather conditions, due to the under-size floor drain also if it becomes blocked.
