Proper Waterproofing in Balconies

This is what we observed during a recent inspection of a 4 Bedroom villa with large balcony on top of the garage. Signs of moisture intrusion on the garage ceiling that was confirmed by the condition of the balcony on the 2nd. floor.
Make sure you do a "pre-handover" inspection of the water proofing to prevent damages like this, which can be costly !
