Steel Column Protection Below Grade

(OP)
Do steel columns below grade need to be protected when in contact with soil?

Normally we use a concrete diamond pour back/isolation joint down to the top of the footing, for the slab which by defalut protects the column from soil interaction.  However, we have a particualar job where we are being asked to place gravel around the column, instead of concrete.   Will this require any additional protection for the column?  

RE: Steel Column Protection Below Grade

We always galvanize any portion of the column below grade (that is not surrounded by concrete).  It seems like water could make its way to your column pretty easily with only gravel.

bituminous paint or concrete encase.

RE: Steel Column Protection Below Grade

We specify bituminous paint (or we usually call it "asphaltic based paint").

 

RE: Steel Column Protection Below Grade

bituminous paint coating is the standard way of dealing with this in th UK

RE: Steel Column Protection Below Grade

I can't see that placing compacted gravel would be much cheaper than pouring in some mass concrete.
