The plug is isolated from the concrete slab by a cylinder of rubber down to a depth of 100mm. From there, both the plug and the slab are in contact with the ground. The pier is held down by six chemset bolts. The mount is a Paramount ME, so I'm assuming it's pretty good quality and vibration free. Movement in the dome will also be dampened by marine grade carpet/rubber backed. Do you see, in your opinion as an engineer, the need to fill the pier with sand? I can always retrofit this thing if needed, but it's going to be impossible to take out if I change my mind. The decision is an important one since it is entirely for public (high school/college) education, and hence there is a severe pressure to do a lot with a very limited budget. In other words, I need to get it right.
Cheers,
Geoff Mc
