Rudy,

Sorry, I cannot agree with you re silica gel. That can become very
conductive if it has absorbed water, especially the blue-dry pink-wet
variety, which is ionic (contains cobalt chloride). However, if present
as a floor filling, it would probably be quartz sand which, if washed,
should not cause electrical problems (note some quartz sand deposits may
contain salt).
