RE: Columns below grade line

[Subject Prev][Subject Next][Thread Prev][Thread Next]
The 3" cover applies only to concrete cast against earth.  If the column is formed and then soil is filled around it the required cover is 2" for #6 or larger and 1-1/2" for #5 or smaller.
There is a section of the commentary that addresses "Alternative methods of protecting the reinforcement" but I do not have any further information.

Columns below grade line needs at least  3" concrete cover. Will using 1.5" cover but apply epoxy
paint to the rebars be OK.
