Currently working with a team on a multifamily project in South Florida that has concrete steel reinforced balconies with post aluminum railings.
Correct me if I am wrong but the two most common ways for installing balcony railings are:
1. Form and Pour the slab then core drill 4" hole for railing post
OR
2. Form and pour the slab with blockouts for the railing posts.
Then epoxy/grout the posts in place to install the railings.
In scenario 1, I imagine it is extremely common that rebar is cut/hit and if any water gets into these post holes when the grout/epoxy shrinks/expands due to changes in weather it leads to corrosion and concrete spalling - long term.
Scenario 2 probably less likely for long term spalling. Is this a common practice?
My post is to see if there are any recommendations on the design of the balcony steel for minimizing potential rebar corrosion issues long term due to balcony railing post installations.
