Spalling of Reinforced Cement Concrete
I noticed that there is significant spalling of concrete slab above the parking lot at 229 Hotham St. There is a section which has already spalled off and more areas which are flaky and can spall off any time on the car parked below.
Spalling phenomenon is quite common in old reinforced concrete structures caused due to insufficient cover to reinforcement. There are multiple techniques to fix this like shotcreting.
