[TowerTalk] Pier-pad foundation, under a house?

[Joe Subich, W4TV]

Don't even think of undermining the house.  If you need to stick with
the 15' pad.move the appropriate distance away from your foundation.
The typical Florida home is slab on grade.  Your area has enough issues
with sink holes, etc.  I would not risk creating one artificially.
