Buried Steel Column Base Plate
Buried Steel Column Base Plate
(OP)
After exhausting all options, I am stuck placing steel column base plates below grade, directly on the footings.
My question is: What is the best method of protection?
I have previous, similar designs to my current project, as well as the more experienced designers in the office, and the best suggestion I am getting is to maintain the status quo, using the standard "Apply 2 coats of black asphaltum to below grade steel." I have made many design improvements over the previous projects, so I am not satisfied with this answer.
I understand this was the standard practice for many years and after doing some research I have not found any new innovations.
Does anyone have any suggestions?

That makes a massive turn down, might require formwork, and needs about 12 cy of extra concrete over the entire project. This leads to using a pedestal with surface mounted base plate instead. I have already eliminated this option.
I'll use the standard coating if I need to, it just seems to be an outdated practice.
Thanks for the quick posts, its appreciated.

What about a sacrificial zinc anode placed near the base of each column?

No asphalt, probably less concrete than turning down the slab.
Asphaltic coating may be antiquated, but the cost for other solutions make it a good choice.

Otherwise the solutions noted above are fine.

Change is not necessarily improvement nor innovation. Matching the cost-effective solution to a problem is still innovation, since so many times that doesn't happen!
