[Tower-Speak] One-Man Towers

[Robin Midgett]

Hi Dave,
The fact that it is split is a sign of a bug in the installation. There 
should be a bed of gravel in the bottom of the hole to allow the leg tubes 
to drain. If there is, then something else is clogging the passage.
As for repairing the torn section, the split can be beaten back together 
with careful application of a ball pein hammer, then welded, preferable 
with a small portable MIG (wire feed) welding rig or if the skills are 
available, a gas welding rig. After that, clean the new joint with a wire 
brush (in a drill chuck), and coat with cold galvanizing spray, available 
at Home Depot or Lowes, made by Rustoleum.
This procedure will restore the mechanical integrity of the leg and slow 
the rusting process, but there's probably still something causing the water 
to build up in the leg, which may lead to another failure.
