condensation inside steel column
condensation inside steel column
(OP)
I am trying to find a solution to controlling condensation inside 4x4 steel post approximately 36" high used in the construction of railing on a project. These post have a 1 1/4" dia x 12" long piece of round stock welded to the bottom of them which is set into holes drilled in the concrete and grouted into the concrete. Drilling holes into the side of the post down low will only make rust run out all over the walk way and is not the preferred solution. A coworker suggested using 2 part expanding urethane foam and pouring it into the columns to prevent moisture from attaching itself to the inside of the steel. Any suggestions on how to solve this issue.

(Although you will get pumping of air in and out as the barometric pressure changes, precipitation usually comes with decreasing pressure, which means you will not draw moist air in by that mechanism.)
