TT:
Regarding "bitumastic" on tower sections in concrete, I'd recommend
applying the material to only the top six inches or so within the concrete,
continuing the coating out of the concrete to six inches above the
foundation. This will provide corrosion protection to the tower legs
against standing water (from accumulated snow, rain puddles, etc.) on the
concrete pad. Covering up the deeply embedded tower does little to prevent
corrosion (no or little oxygen in the concrete). You also lose some
serendipitous grounding (unintentional Ufer ground) when you insulate the
tower from the conductive concrete mixture. (This is not my idea - credit
goes to N3RR who gave me an education at his tower farm last year.)
