This was my balcony after the tile was removed. You can see where rebar rusts, it expands popping cement and tile. You can also see where previous management, prior to my purchase) decided to caulk the cracks with in-house maintenance rather than do a proper repair.
I was part of a very vocal group during the few years prior to this project, demanding work done by properly per engineering reports. While our board of directors berated us they at first claimed it was all 'cosmetic' Then spent two years trying to find an engineer that would back them up. The final engineer actually deemed my balcony as uninhabitable, removed and replaced the whole thing.
The final cost was over 8 million, including balcony repair, waterproofing and refinishing the exteriors, and replacing and repairing many of the columns in the lower level parking. |
We have owned a ground floor condo in a 4 story building in Cocoa Beach Fl. for over 20 years. It was built in 1975. I don't believe post tension was used at that time. All floors and interior walls are poured concrete (not the roof). We do have balconies but they are individual and not the huge wrap around balconies as pictured. Our HOA board is very proactive about concrete deterioration and we have replaced walkways and balconies and have an annual engineered inspection. I've noticed that the balconies on the subject condo are tiled. Our engineers (many years ago) determined that tile was the main cause of the problem. Thus there is no tile or even welcome mats allowed on the balconies or even ground floor patios or walkways. Also, most building codes do not allow ground floors units anymore, thus most condos are built on posts and piers with huge openings for ground floor and even underground parking. That could prove to be part of the problem!
